Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z Dhillon and the team think Quaoar's ring formed similarly to other solar system rings: Collisions of moonlets orbiting the parent planet created debris that settled into a ring made of rock, ice and dust particles. 'Impossible' New Ring System Discovered at the Edge of the Solar System 2023-02-11T05:00:00Z Rather, astronomers found it indirectly, when distant stars happened to pass behind Quaoar, blocking the starlight. There’s a Ring Around This Dwarf Planet. It Shouldn’t Be There. 2023-02-08T05:00:00Z Yet while Pluto has been joined by objects that rival it in size—worlds such as Makemake, Haumea, Quaoar and Eris—nothing has yet been found that comes close to any of the planets. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Quaoar just happens to be located near the plane of the galaxy, says Fraser, so there are lots of field stars in the background. Probing the Solar System's Icy Fringes 2013-08-22T11:08:00Z Another occultation occurred on Aug. 9 last year, and astronomers again pointed telescopes, large and small, at Quaoar in hopes of learning more about the ring. Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z Elastic collisions may be possible if the ring particles have an icy outer coating, Dhillon said — something that is plausible, given Quaoar's location at the edge of the solar system. 'Impossible' New Ring System Discovered at the Edge of the Solar System 2023-02-11T05:00:00Z From 2018 through 2021, Quaoar passed in front of four stars, and astronomers on Earth were able to observe the shadow of the eclipses, also known as stellar occultations. There’s a Ring Around This Dwarf Planet. It Shouldn’t Be There. 2023-02-08T05:00:00Z And if so, why not Quaoar and Sedna, and several other worlds, which were smaller than Pluto, but not by much? Pluto Has a Twin Sister: Frigid Dwarf Planet Eris 2011-10-31T09:15:00Z The star marked by the red circle is actually a combined image of Quaoar and the star it nearly occulted. Probing the Solar System's Icy Fringes 2013-08-22T11:08:00Z “This event involves a bright star and will be useful to constrain the Quaoar shape better, in addition to being a good opportunity to obtain more details about these two remarkable rings,” Mr. Pereira said. Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z The researchers discovered the ring system while investigating whether Quaoar has an atmosphere. 'Impossible' New Ring System Discovered at the Edge of the Solar System 2023-02-11T05:00:00Z A potential explanation for Quaoar’s distant ring is the presence of Weywot. There’s a Ring Around This Dwarf Planet. It Shouldn’t Be There. 2023-02-08T05:00:00Z Even more exciting are the occultation results of Quaoar, a relatively large Kuiper Belt Object named after the creator god of the Tongva Native Americans. The Revelations of Planets' Shadows 2011-10-05T21:21:08Z Another, Quaoar, might be only 900 kilometers wide, compared with earlier estimates of 1,200 kilometers. The War of the Worlds, Round 2 2011-01-10T20:46:17Z A potential explanation for Quaoar’s distant rings is the presence of a moon, Weywot. Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z The ring became visible when it caused a roughly 5% to 10% dip in light from a background star, both before and after the main body of Quaoar passed in front of the star.

Brown, an astronomer at the California Institute of Technology who was a co-discoverer of Quaoar in 2002, said the discovery of the ring baffled him. There’s a Ring Around This Dwarf Planet. It Shouldn’t Be There. 2023-02-08T05:00:00Z Instead, at one side of Quaoar, there appears to be "a lack of object," as Braga Ribas describes it. The Revelations of Planets' Shadows 2011-10-05T21:21:08Z For Quaoar, the Roche limit is calculated to be 1,100 miles. Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z “This implies that Quaoar is a more complex system than we initially thought.” Why Have One ‘Impossible’ Ring Around Your World When You Could Have Two? 2023-04-27T04:00:00Z The ring of Quaoar is too small and too faint to be seen via direct imaging, even with an instrument as powerful as the Hubble Space Telescope. 'Impossible' New Ring System Discovered at the Edge of the Solar System 2023-02-11T05:00:00Z The second ring, at a distance of 1,500 miles from the center of Quaoar, is closer than the ring announced in February, which has a radius of about 2,500 miles.
