A mysterious Mars-sized planet may be hiding at the edge of our solar system 2017-06-27T04:00:00Z A new study reveals that a group of icy bodies in the solar system’s Kuiper belt may not, as previously thought, indicate the presence of a ninth planet, according to a report by Nature. Planet Nine may not exist after all 2017-06-27T04:00:00Z There is another part of the Kuiper belt called the kernel, a narrow stream of icy fragments whose orbits are not currently synced to Neptune’s. Orbital Forensics Hint at Sun's Long-Lost Planet 2018-10-05T04:00:00Z And it could be rockier than expected, as a recent astronomical campaign focused on the Kuiper belt object hinted, says Wesley Fraser, an astronomer at Queen’s University Belfast in Northern Ireland. NASA spacecraft readies for New Year's rendezvous with primordial object far beyond Pluto 2018-12-27T05:00:00Z The bodies that piqued the astronomers’ interest dwell in the outer reaches of the Kuiper belt. Solar System survey casts doubt on mysertious 'Planet Nine' 2017-06-21T04:00:00Z Most Centaurs orbit in the general direction of planetary motion, pointing to an origin in the Kuiper belt — a reservoir of remnants from the Solar System's formation that is situated beyond Neptune's orbit.

Not so lonely sea in the sky 2016-11-17T05:00:00Z Even with the new data, the best explanation for the odd grouping of Kuiper belt objects is a planet, he says. Solar System survey casts doubt on mysertious 'Planet Nine' 2017-06-21T04:00:00Z She said these clues suggest similar activity on Eris, another dwarf planet in the Kuiper belt, the distant ring of the solar system where Pluto orbits. Nasa findings hint of clouds on Pluto during New Horizons mission 2016-10-18T04:00:00Z As New Horizons sails on to its next target, a body in the Kuiper belt provisionally called 2014 MU69, it is continuing to beam data back to Earth. 5 Amazing Things We’ve Learned a Year After Visiting Pluto 2016-07-14T04:00:00Z But there are a slew of additional Kuiper belt objects larger than Mimas. Astronomers Discover New Likely Dwarf Planet 2016-07-13T04:00:00Z “This object is probably about a top-20 Kuiper belt object,” says astronomer Scott Sheppard of the Carnegie Institution of Washington, who wasn’t involved with the discovery. Why We Missed This Nearby Mini-Planet for So Long 2016-07-12T04:00:00Z Yet the question remains, if the formation of the solar system prevented an Earth-size planet from being in the Kuiper belt, why didn’t it prevent the still larger Planet Nine? 2006: a space oddity – the great Pluto debate 2016-05-01T04:00:00Z Scientists sometimes call it the outermost Kuiper belt or the innermost Oort cloud — the next region of the Solar System, which is thought to extend to at least 100,000 AU. On the hunt for a mystery planet 2016-03-14T04:00:00Z According to his simulations, a large planet in such a bizarre orbit would send some Kuiper belt objects into orbits that ran perpendicular to the planets in the solar system. Evidence suggests huge ninth planet exists past Pluto at solar system's edge 2016-01-20T05:00:00Z Dr. Brown’s computer keeps track of large Kuiper belt objects, and currently, 96 of them appear to be larger than Mimas and thus likely to be round dwarf planets.

On the hunt for a mystery planet 2016-03-14T04:00:00Z The researchers found that six of the 13 Kuiper belt objects moved on orbits that headed in the same direction. Evidence suggests huge ninth planet exists past Pluto at solar system's edge 2016-01-20T05:00:00Z That range would put it far beyond Pluto, in the realm of icy bodies known as the Kuiper belt. Evidence grows for giant planet on fringes of Solar System 2016-01-19T05:00:00Z While the team hasn’t determined 2015 RR245’s composition, it’s probable that, like Pluto and other Kuiper belt dwarf planets, the object is a frozen wonderland of volatile ices, perhaps with a dash of rock. Why We Missed This Nearby Mini-Planet for So Long 2016-07-12T04:00:00Z The Kuiper belt extends outward from Neptune’s orbit, about 2.8 billion miles from the sun, to a bit less than twice Neptune’s orbit, about five billion miles. Ninth Planet May Exist Beyond Pluto, Scientists Report 2016-01-20T05:00:00Z They worked together to hunt Kuiper belt objects, and then started a systematic survey to search for still more-distant worlds. On the hunt for a mystery planet 2016-03-14T04:00:00Z The astronomers wondered whether the Kuiper belt might hold enough rocky debris from the birth of the solar system to nudge the objects into the same orbits. Evidence suggests huge ninth planet exists past Pluto at solar system's edge 2016-01-20T05:00:00Z The spacecraft is now heading off past the edge of the solar system, into a zone called the Kuiper belt, and should reach its next destination, a body called 2014MU69, in 2019.

On the hunt for a mystery planet 2016-03-14T04:00:00Z New Horizons continues to move deeper into the Kuiper belt, or what astronomers call the third zone of space. New Horizons probe beams back sharpest ever images of Pluto 2015-12-05T05:00:00Z New Horizons is now on course for its next rendezvous in 2019, with an object called 2014MU69 in the Kuiper belt, which lies beyond the orbit of Neptune. Pluto as we know it now: Nasa report unwraps enigma of dwarf planet 2015-10-15T04:00:00Z New Horizons is now venturing farther into the Kuiper belt, a region of dwarf planets and ancient debris that rings the solar system’s farthest edge. New Horizons images show Pluto has blue skies and red water ice 2015-10-08T04:00:00Z Dr. Batygin, a theorist, tried placing a planet among them using computer simulations, which scattered some Kuiper belt objects, but the orbits were not sufficiently eccentric. Ninth Planet May Exist Beyond Pluto, Scientists Report 2016-01-20T05:00:00Z The Kuiper belt seemed to extend neatly from about 30 AU to 50 AU, with most objects following stately orbits around the Sun. On the hunt for a mystery planet 2016-03-14T04:00:00Z The spacecraft is now more than 3bn miles away from Earth and heading into the Kuiper belt, toward an object dubbed PT1 – “potential target one” – on the edge of the solar system.

Watching the Pluto flyby with the New Horizons team 2015-07-16T04:00:00Z Another strange result in the simulations: A few Kuiper belt objects were knocked into orbits perpendicular to those of the planets. Ninth Planet May Exist Beyond Pluto, Scientists Report 2016-01-20T05:00:00Z Anything slower than that must be beyond the main Kuiper belt and is something that interests the search team. On the hunt for a mystery planet 2016-03-14T04:00:00Z The mountains—and their implication of mountain-building activity—runs counter to the expectation that Kuiper belt objects are cold, pristine relics. Pluto is alive—but where is the heat coming from? 2015-07-15T04:00:00Z The Kuiper belt is the source of some comets - those with orbits that bring them around the sun every 200 years or so. Editorials from around New England 2015-07-18T04:00:00Z If all goes well, New Horizons will continue traveling outward to encounter other denizens of the Kuiper belt, the vast zone of icy wreckage beyond the known planets. A Window Into Pluto, and Hopes of Opening Other Doors 2015-07-15T04:00:00Z Adding that one of the biggest surprises was the discovery that “there are mountains in the Kuiper belt”, the solar system’s mysterious “third zone” where Pluto sits amid around 100,000 smaller icy objects. Pluto pictures: Nasa reveals first high-resolution images of planet's surface 2015-07-15T04:00:00Z But Sedna and other objects beyond the main Kuiper belt probably weren't born where they are today, because there simply wasn't enough gas and dust available at those great distances to create sizeable worlds.

Editorials from around New England 2015-07-18T04:00:00Z “You’re simply moving it from the smallest of planets to the king of the Kuiper belt.” Who you calling a dwarf? Pluto flyby reopens debate about its 'planet' status 2015-07-15T04:00:00Z Scientists hope that the objects in the Kuiper belt, including Pluto, will offer us a window back in time, potentially helping to explain the Earth’s own origins. Pluto pictures: Nasa reveals first high-resolution images of planet's surface 2015-07-15T04:00:00Z They found that the closest it ever gets to the Sun — a measure known as its perihelion — is 80 AU, beyond the bulk of the Kuiper belt. On the hunt for a mystery planet 2016-03-14T04:00:00Z But Lunine says it could be that the dynamics of the Kuiper belt are different from those in the rest of the solar system. Pluto is alive—but where is the heat coming from? 2015-07-15T04:00:00Z New Horizons is alive and on its way to the inner Kuiper belt, according to NASA. Pluto probe is alive and healthy 2015-07-14T04:00:00Z His initial impression is that Pluto is far more cratered than Triton, the moon of Neptune that is about the same size as Pluto and is thought to be a captured Kuiper belt object. Pluto's icy face revealed as New Horizons flyby occurs 2015-07-14T04:00:00Z This applies to Pluto, Eris and a few other Kuiper belt objects, and also to the largest asteroid, Ceres. NASA Mission Brings Pluto Into Sharp Focus — But It's Still Not a Planet 2015-07-14T04:00:00Z Malhotra's team uses four extreme Kuiper belt objects to suggest that an unseen planet moves around the Sun every 17,000 years. On the hunt for a mystery planet 2016-03-14T04:00:00Z The new measurements confirm it as the reigning king of the Kuiper belt, outsizing Eris by about 30 kilometers. At Pluto, the End of a Beginning 2015-07-14T04:00:00Z With New Horizons weighing in, “that settles the debate about the largest object in the Kuiper belt,” Dr. Stern said. A Close-Up for Pluto After Spacecraft’s 3-Billion-Mile Trip 2015-07-13T04:00:00Z “Why can’t we call Pluto a planet and a Kuiper belt object?” he asks. Pluto's icy face revealed as New Horizons flyby occurs 2015-07-14T04:00:00Z There are more than a thousand objects now documented in what is called the Kuiper belt, a region beyond Neptune where it seems no large objects were able to form. NASA Mission Brings Pluto Into Sharp Focus — But It's Still Not a Planet 2015-07-14T04:00:00Z Do you think we'll send another mission to Pluto or the Kuiper belt?

Nasa's New Horizons probe in final countdown to Pluto flyby 2015-07-10T04:00:00Z While Pluto is now the biggest in the Kuiper belt, Eris remains the heavyweight — 27 percent more massive than Pluto. A Close-Up for Pluto After Spacecraft’s 3-Billion-Mile Trip 2015-07-13T04:00:00Z What New Horizons will not discover is what might lie beyond the Kuiper belt; its camera is not designed to scan the sky for dark objects. Almost Time for Pluto’s Close-Up 2015-07-06T04:00:00Z No longer the smallest of the planets, Pluto is the king of the Kuiper belt. Feature: How Alan Stern’s tenacity, drive, and command got a NASA spacecraft to Pluto 2015-06-25T04:00:00Z We began planning this mission back in 1989, after Voyager 2's encounter with Neptune, and back then hardly anyone even knew the Kuiper belt existed. Pluto Lover Alan Stern Discusses Historic July Flyby [Q&A] 2015-07-13T04:00:00Z Pluto is the largest known object in the Kuiper belt. Nasa's New Horizons probe in final countdown to Pluto flyby 2015-07-10T04:00:00Z The discovery in 2005 of Eris, a more distant Kuiper belt object, set off the events that led to Pluto’s demotion to dwarf planet, a new category. A Close-Up for Pluto After Spacecraft’s 3-Billion-Mile Trip 2015-07-13T04:00:00Z At its closest point to the sun, it is still beyond the Kuiper belt. Almost Time for Pluto’s Close-Up 2015-07-06T04:00:00Z The ring is about the same distance from its parent star as the Kuiper belt is from the Sun, and receives roughly the same amount of light. Nearby star hosts Kuiper belt twin 2015-05-27T04:00:00Z The portion of the disk where the chemicals were observed is roughly analogous to our solar system’s Kuiper belt, the realm of comets and icy bodies that lies beyond Neptune. Organic molecules found circling nearby star 2015-04-08T04:00:00Z The largest structure in our planetary system, the Kuiper belt is home to comets and more than 100,000 miniature worlds less than 62 miles across. Nasa's New Horizons probe in final countdown to Pluto flyby 2015-07-10T04:00:00Z Pluto — just one among many objects in the Kuiper belt — fails this test, effectively demoting it from planet to dwarf planet. Pluto's long, strange history — in pictures 2015-02-17T05:00:00Z Once there it will explore the dwarf planet and its moons before moving on to travel through the Kuiper belt — the massive asteroid belt that fringes our Solar System. The CPU from the original PlayStation is guiding a probe to Pluto 2015-01-15T05:00:00Z The Kuiper belt, a remnant of that era, contains leftover material from the formation of the icy outer planets. Nearby star hosts Kuiper belt twin 2015-05-27T04:00:00Z And K2 will look closely at sections of our own solar system, particularly the objects in the Kuiper belt. This is how NASA rescued its planet-hunting telescope 2014-12-30T05:00:00Z Given what Herschel found at Hartley 2, it appeared that Kuiper belt comets are chemically different from those that hail from the Oort cloud. Dying for a Drink: How the Earth Got its Water 2014-12-11T05:00:00Z It is the first Kuiper belt object known other than Pluto, and its existence confirms that Pluto is not alone in the outer Solar System. Pluto's long, strange history — in pictures 2015-02-17T05:00:00Z Halley is from a more distant region. 67P, which is from the Kuiper belt as well, changed that thinking. New Data from Rosetta, Comet 67P, Back Theory of Cataclysm That Flung Planets Around the Solar System 2014-12-10T05:00:00Z Nobody would realize until the 1980s, however, that such a thing as the Kuiper belt even existed. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z The spacecraft was meant to fly first past Pluto and then past another object in the cluster of icy bodies known as the Kuiper belt.

New Dwarf Planet Has Most Distant Trajectory Known 2014-03-26T21:00:00Z Admittedly, there's an even farther frontier out in the Kuiper belt, not to mention the Oort cloud beyond, but ... Me and my flying saucer 2014-01-29T18:51:59.174Z Something must have happened early in the solar system's history to snuff out the largest members of the Kuiper belt. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z There are citizen scientists out very late at night, to size up the Kuiper belt. Physics Week in Review: January 25, 2014 2014-01-25T05:52:03Z According to his theory, the large Kuiper belt objects formed first. Astronomers Surprised by Large Space Rock Less Dense than Water 2013-11-15T18:15:11.370Z Another possibility is that a massive rogue planet passed through at some point, kicking objects from the Kuiper belt outwards into the inner Oort cloud. New Dwarf Planet Has Most Distant Trajectory Known 2014-03-26T21:00:00Z The record holder is also easy to find, it’s the New Horizons mission to Pluto and the Kuiper belt. The Fastest Spacecraft Ever? 2013-02-25T16:45:07.763Z Ejection Model By the time the Kuiper belt was discovered, physicists had already established how the solar system came to be. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Currently Makemake is near aphelion, the point farthest from the sun along its 307-year orbit in the Kuiper belt, a ring of comets and other icy objects beyond Neptune. Rare Apparition of Dwarf Planet Makemake Reveals a Largely Airless World 2012-11-21T19:45:00.177Z If large bodies in the Kuiper belt were made by the merging of small ones, the densities of the small and big bodies should be related. Astronomers Surprised by Large Space Rock Less Dense than Water 2013-11-15T18:15:11.370Z A Kuiper belt Tokyo would get brighter and dimmer with that motion, and it would do so according to Newton's inverse-square law. Cities on Pluto? Solar System Speculation 2011-11-10T09:30:00Z Jupiter family comets most likely formed in the Kuiper belt on the outer fringes of the Solar System and migrated inwards. Comets May Have Supplied The Earth's Ocean Water 2011-10-06T23:04:19Z The very existence of the Kuiper belt therefore appears inconsistent with how theorists believe it must have formed. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Pluto was the first object to be found in what’s now known as the Kuiper belt, a region that’s also full of asteroids. Find An Asteroid To Visit 2011-06-25T04:45:00.240Z This process ultimately built dwarf planets in the Kuiper belt, such as Pluto, as well as Earth and the other rocky planets in the inner Solar System. Astronomers Surprised by Large Space Rock Less Dense than Water 2013-11-15T18:15:11.370Z OK, the fact is it's vanishingly unlikely that there's some thriving Manhattan or Minneapolis stuck on an ice-ball in the depths of the Kuiper belt. Cities on Pluto? Solar System Speculation 2011-11-10T09:30:00Z Kuiper belt comets also orbit the sun much faster. Comets May Have Supplied The Earth's Ocean Water 2011-10-06T23:04:19Z The other problem is that there is not enough matter in the Kuiper belt to account for the existence of any objects of any size. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z “You can compare those two,” Stern says, “and find out how the impact history has changed, what the size range of projectiles is today versus what it was in the ancient Kuiper belt.” Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z The body, dubbed 2002 UX25, lies in the Kuiper belt, a reservoir of dwarf planets, comets and smaller frozen bodies beyond the orbit of Neptune. Astronomers Surprised by Large Space Rock Less Dense than Water 2013-11-15T18:15:11.370Z Many objects in the Kuiper belt — the ring of comets and other bodies that surround the solar system — are in highly elliptical orbits, meaning they get closer and farther away as they orbit the sun. Cities on Pluto? Solar System Speculation 2011-11-10T09:30:00Z Pluto's Close-up Models and remote observations have told planetary scientists an enormous amount about the structure and likely history of the Kuiper belt. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z “The consensus solution,” Jewitt says, “is that in the beginning there was far more material—30, 40 or even 50 Earth masses' worth” in the Kuiper belt. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Just a bit more than 20 years ago, in fact, nobody even knew that the Kuiper belt existed. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z The object's low density and size — it is 650 kilometers wide — seem to conflict with a leading model for the formation of large solid bodies in the Kuiper belt and throughout the Solar System. Astronomers Surprised by Large Space Rock Less Dense than Water 2013-11-15T18:15:11.370Z What Tombaugh had actually found was the brightest member of the Kuiper belt. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z “For every asteroid in the main asteroid belt,” Jewitt says, “there are 1,000 objects in the Kuiper belt. It's staggering to me.” Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z In this view, the Kuiper belt is like a snapshot, frozen in time, of what the rocky inner solar system looked like just a few million years after the planet-formation process had gotten under way. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z If the reshuffling of the giant planets really happened, it could explain why the Kuiper belt has no truly large objects: the material that would have built them was prematurely swept away. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Many astronomers, however, are more shocked by what isn't in the Kuiper belt. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Each of these observations has served as a narrow window into the origin and evolution of the Kuiper belt.
