Catholic Churchmen in Science "Yes," Deering said quietly, "and I have been trying a long time to forget what we did to that planetoid." The Huddlers All knew without asking that the baron was born in space, his birthplace one of the planetoid city-states of the Michea Dwarf. The Ties That Bind The Gnii," the Manager of Trade, a large, red-faced man said, "demand that we remove our trading planetoid from their system. Mr. President "In the light of what I have learned, the losses of time, life, and treasure—even the loss of the planetoid—are completely insignificant." Triplanetary I had to visit briefly hundreds of the lateral worlds, hovering over primordial swamps, limitless oceans, insect kingdoms and radioactive planetoids, before I found the one that was truly parallel. Back to Julie They were like nothing he had ever seen on either Earth or Mars or any of the planetoids between. The Golden Amazons of Venus Diogenes actually scraped her superstructure, with a noise that made every hair on her captain's neck stand upright; the others missed the planetoid by no more than a foot or two. The Giants From Outer Space "I don't recall any alien trading planetoids in our system." Mr. President The surviving scientists of the planetoid, expert gunners and ray-men all, destroyed many of the projectiles, but it was not humanly possible to cope with them all.

Anything You Can Do! Almost immediately after he had landed in the darkness that blanketed the surface of the planetoid, a big space yacht settled down near him. The Planetoid of Peril As the years passed, the air pump began to labor a little as it converted the oxygen in the planetoid's rock into a breathable atmosphere. Beside Still Waters Still, considering that there remain probably an immense number of planetoids to be discovered, it is quite possible that among these there may be some having orbits answering to the requirement. Essays: Scientific, Political, & Speculative, Vol. I If we had encountered even a planetoid at that enormous rate, we would probably have been annihilated in white-hot death.

Essays: Scientific, Political, & Speculative, Vol. I It's a dead, airless pip-squeak planetoid, just a big mile-thick rock, probably. Shipwreck in the Sky The men inside the planetoid certainly should not have been able to pick up any more than the beginning of the conversation, before it had been cut off by solid rock. Anything You Can Do! According to its orbit and location, and the spectroscopic table of its mineral resources, it was a choice planetoid indeed. The Planetoid of Peril As later estimates, however, considerably exceed this, it will, perhaps, be not far from the truth to state that they are each roughly about the size of the planetoid Eros. Astronomy of To-day A Popular Introduction in Non-Technical Language The argument set forth in the foregoing note, is in part designed to introduce a question which seems to require re-consideration—the origin of the minor planets or planetoids.

The Astronomy of Milton's 'Paradise Lost' The relative positions of planetoids in the Belt just keep on shifting. The Risk Profession In point of view, however, of its small size, it can hardly be considered as a true planet, and the name "planetoid" seems much more appropriate to it. Astronomy of To-day A Popular Introduction in Non-Technical Language As a preliminary to closer consideration, let us ask what may be inferred from the rate of discovery of the planetoids, and from the sizes of those most recently discovered. Essays: Scientific, Political, & Speculative, Vol. I The question of separate Primitive Impulses for separate bodies becomes more and more incongruous and inadmissible, as we consider it in its application to such small bodies as meteors and planetoids. Aether and Gravitation The planetoid they were on—or rather, in—was known throughout the Belt simply as Threadneedle Street, and was nowhere near as large as Ceres. Anything You Can Do ... I had to break his story somehow, and in order to do that I had to do some nosing around on this planetoid. The Risk Profession The really big babies had to be parked in an orbit and loaded by shuttle; they'd break up of their own weight if they tried to set down on anything bigger than a good-sized planetoid. The Highest Treason The apparent brightness, as expressed in equivalent star-magnitudes, is the only index we have to the probable comparative sizes of by far the largest number of the planetoids: the exceptions being among those first discovered. Essays: Scientific, Political, & Speculative, Vol. I Now if the orbits of the planetoids be such an entangled mass, what must be the orbits of these meteors? Aether and Gravitation The man who called himself Stanley Martin had carefully plotted the orbit of this particular planetoid and had let his spaceboat coast in without using any detection equipment except the visual. Anything You Can Do ... It was silly of course—there was some gravity on that planetoid, after all—but I just don't seem to get used to low-gee. The Risk Profession Ceres has a pretty respectable gee pull for a planetoid: Three per cent of Standard. A Spaceship Named McGuire That is to say, nearly all of them frequent the same region as the planetoids. Essays: Scientific, Political, & Speculative, Vol. I Somewhere on the surface of that tiny planetoid racing in toward the Sun they knew they would find Roger Hunter's secret. Gold in the Sky If their paths were exactly circular, then no two of that vast number of planetoids would ever collide. Anything You Can Do ... The next three levels have all been burned into the bowels of the planetoid. The Risk Profession The field was about the size of a football field, a bright, shiny expanse of rough-polished metal, carved and smoothed flat from the nickel-iron of the planetoid itself. A Spaceship Named McGuire Then St. Simon launched himself out the open door toward the surface of the planetoid. Anchorite They stared at the ragged surface of the planetoid. Gold in the Sky Granted, the chance of any given metallic planetoid's being selected was very small—but they had not wanted to take even that chance. Anything You Can Do ... Nat had barely raised his ship from the Asteroid Moira when he saw the small planetoid lurch suddenly, bounding off its orbit at almost a right angle. The Beast of Space It not only served as a landing field, but as a reflector beacon, a mirror that flashed out the sun's reflection as the planetoid turned slowly on its axis. A Spaceship Named McGuire St. Simon again matched the velocity of the Nancy Bell with that of the planetoid, which had been accelerated by the drill's action. Anchorite Not to mention the Iscariot which Le Verrier and Adams calculated into existence, there is more than a septuagint of new planetoids. A Budget of Paradoxes, Volume I He climbed out of the little grotto where he had concealed himself and moved toward the spot where he knew the airlock to the caverns underneath the planetoid's surface was hidden. Anything You Can Do ... As clothing it was superfluous on this tropical planetoid. The Devil's Asteroid But a planetoid is in a different class altogether. A Spaceship Named McGuire It grated a couple of times, but between the power of the ship and the mass of the planetoid, there was enough pressure to push it past the obstacles. Anchorite I take it for granted that you know as well as I do that when it comes to roads, there are as many different kinds of roads as there are planetoids in the solar system. The House An Episode in the Lives of Reuben Baker, Astronomer, and of His Wife, Alice He moved silently and with assurance in the fractional-gee field of the planetoid. Anything You Can Do ... In a few moments the space launch was blasting away from the freighter and heading for a tiny planetoid in the distance. On the Trail of the Space Pirates When you're carving an office and residence out of a nickel-iron planetoid, importing wood from Earth is a purely luxury matter. A Spaceship Named McGuire The tugs would be able to find the planetoid by following the beeps. Anchorite His laboratory was a power-house; at his command were the stupendous forces of a battery of planetoid accumulators, and added to these were the fourth-order, ninth-magnitude forces of the disintegrating copper bar. Skylark Three The boy, held prisoner for more than ten weeks on a small planetoid, was reported in good health. Anything You Can Do ... Soon they felt the unmistakable jar and bump of the small space vessel touching the surface of the planetoid. On the Trail of the Space Pirates On Ceres, as on most of the major planetoids, a man's home is his castle, even if it's only a hotel room. A Spaceship Named McGuire The planetoid was turning under him, which made the ship appear to be circling slowly around his worksite. Anchorite With a ship like that, you could run through a planetoid without hurting the hull. Islands of Space "I was just going to suggest that we clean up that planetoid Roger started, but I see that the local boys are attending to it." Triplanetary Then the young cadet saw the invading spaceship move away from the area around the tower toward the horizon not too far away on the small planetoid. On the Trail of the Space Pirates It was standing upright on the surface of the planetoid, a shining needle in the shifting sunlight, limned against the star-filled darkness of space. A Spaceship Named McGuire When the drill was firmly based on the surface of the planetoid, St. Simon hauled his way back to his ship along his safety line. Anchorite We now know that it contains about nine hundred "planetoids," or small globes of from five to five hundred miles in diameter. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told The surviving scientists of the planetoid, expert gunners and ray-men all, destroyed many of the projectiles, but it was not humanly possible to frustrate them all. Triplanetary Moving toward them under full rocket thrust, the Venusian cadet remembered fleetingly stories of survivors of space wrecks, reaching the airless little planetoids, only to die when help failed to arrive. On the Trail of the Space Pirates I had every executive on the planetoid jumping before I was through. A Spaceship Named McGuire The drill began to sink into the surface, and the planetoid began to move ever so slowly. Anchorite A plane of artificial matter formed just beneath it, and sheared it from its bed on the planetoid, cutting through the heavy cosmium anchors. Invaders from the Infinite For this vast planetoid was no feeble warship, depending solely upon the limited power available in its accumulators. Triplanetary The young Solar Guard officer was aware that at any moment after reaching the celestial jungle of small planetoids he could be fired on without warning. On the Trail of the Space Pirates One by one the white puffs of dust from the reactor units were exploding on the surface of the planetoid. Danger in Deep Space The upper one, which tried to push the drill into the surface of the planetoid, developed nearly forty per cent more thrust than the lower one. Anchorite Then a tremendous plane of matter formed, and neatly bisected the planetoid, two great flat pieces of rock were left where one had been—miles across, miles thick—planetary chips. Invaders from the Infinite Instantly the fleet abandoned the attack upon the planetoid and swung its cone around, to bring the flame-erupting axis to bear upon the inchoate something dimly perceptible to the ultra-vision of the Secret Service observers. Triplanetary Almost immediately, a spaceship appeared over the small planetoid and began systematically pounding the surface installations with atomic blasters. On the Trail of the Space Pirates It shot up in a pretouchdown maneuver, and then began to drop slowly to the surface of the planetoid. Danger in Deep Space A drill of that type could be built which would burrow its way right through a small planetoid, but that was hardly necessary for planting an anchor. Anchorite To them life on a planet like Earth was as life to a terrestrian on a planetoid such as Ceres, Juno or Eros would have seemed. Invaders from the Infinite He shut off his offensive beams and surrounded the entire planetoid with the peculiarly rigid and substantial shield which had so easily warded off Costigan's fiercest attacks. Triplanetary All eyes were on the tiny rocket scout as its jets, roaring into life, lifted free of the pirate planetoid. On the Trail of the Space Pirates On the surface of the planetoid, giant mushrooming clouds appeared climbing into the airless void. Danger in Deep Space Then he nudged the Nancy Bell sideways, pushing the bolt down into the planetoid. Anchorite Venone had planetoid stations, that projected molecular rays of an intensity I wonder at, with their system of projecting. Invaders from the Infinite And was there, or was there not, a lesser eruption upon the other side--an almost imperceptible flash, as though something had shot from the doomed planetoid out into space? Triplanetary Later, when a fine boy baby arrived in the Herschel solar system, Caroline forgave all and came to take care of what she called "the Herschel planetoid." Little Journeys to the Homes of the Great - Volume 12 Little Journeys to the Homes of Great Scientists The asteroid he was on was so small and the horizon such a short distance away that the base of Miles' giant black ship was half-covered by the curvature of the planetoid. Treachery in Outer Space He locked the door of his boat and walked down the yellow-painted safety lane toward the nearest air lock leading into the interior of the planetoid. Anchorite Rings of laser arrays along the edge of the Extractor's hopper flashed alive and focused their beams on a large, slowly tumbling planetoid hundreds of kilometers across its minor dimension. The Universe — or Nothing The heavy cruiser Chicago hung motionless in space, thousands of miles distant from the warring fleets of space-ships so viciously attacking and so stubbornly defending the planetoid of the enemy. Triplanetary It was reserved for Guiseppe Piazzi, an Italian astronomer at Palermo, to make known by actual observation the first member of the planetoid group. Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World The middle region between Jupiter and Mars yielded the little planetoid Ceres in 1801, Pallas in 1802, and one hundred and ninety others since. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work "If the planetoids were born of a single small ring, might not several planets be condensed from a large one?" A Trip to Venus Sensors, analyzers, siphons and beam-guides paralleled the lasers' signals along an incandescent column of plasma from the dissolving planetoid into the Extractor's processes and, when ready, into the hopper. The Universe — or Nothing A beam behind which was every volt and ampere that the gigantic generators and accumulators of the planetoid could yield. Triplanetary So they continued the search, and in a little more than a year Olbers himself was rewarded with the discovery of the second of the planetoid group. Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World I embrace the earth with my eyes, the whole of it, the entire little planetoid, and I can find nothing more terrible on it than man and human life. Savva and the Life of Man Two plays by Leonid Andreyev Thus, if we take Mercury as ¾ inch from the sun, Venus is about 1¼ inches, the Earth 2¼, Mars 2, the planetoids 5¼, Jupiter 9¾, Saturn 14, Uranus 36, and Neptune 60 inches. A Trip to Venus One alive, the other void, Double, whirling planetoid. The Little Daisy Girl and Other Poems Mr. Roumann hurried into the pilot house, gave a quick glance at the indicator, and exclaimed: "We are nearing a planetoid, or, as some call them, an asteroid!" Through Space to Mars Or the Longest Journey on Record Perfect bodies group into constellation, called sun's planets, planetoids, and moons. ABC's of Science Thus might be explained the hundreds of planetoids, or minor planets, which we find between Mars and Jupiter. The Story of Evolution Eight large or major planets, with their satellites, and a flock of minor planets or planetoids, are revolving round him as their common centre and luminary at various distances, but all in the same direction. A Trip to Venus Giant ball of green and blue, Lost a planetoid or two. The Little Daisy Girl and Other Poems The planetoids are apparently the rubbish of a ring which has failed to condense into one body, perhaps through its uniformity or thinness. A Trip to Venus I will call the currents carrying constellation sun currents, planet currents, planetoid currents, moon currents, and comet currents, respectively. ABC's of Science About 400 planetoids have been discovered up to now, but we are always catching more of them. A Trip to Venus They are divided by the planetoids into an inner and an outer band. A Trip to Venus If a constellation is formed its current is called sun current, and here it continues to whirl with all its subordinate currents, planet, planetoid, and moon. ABC's of Science |
