They were like nothing he had ever seen on either Earth or Mars or any of theplanetoids between.
They are divided by theplanetoids into an inner and an outer band.
If the planetoids were born of a single small ring, might not several planets be condensed from a large one?
About 400 planetoids have been discovered up to now, but we are always catching more of them.
The planetoids are apparently the rubbish of a ring which has failed to condense into one body, perhaps through its uniformity or thinness.
If their paths were exactly circular, then no two of that vast number of planetoids would ever collide.
It was a solid, roughly spherical mass of nickel-iron, nearly two thirds of a mile in diameter and, like the other inhabited planetoids of the Belt, honeycombed with corridors and rooms cut out of the living metal itself.
What is the distance of these planetoids from the sun?
When and by whom were the four planetoids discovered?
This would be the fifth mapping expedition to the planetoids of Yancy-6 in three generations.
You wouldn't need much more than a jet plane to get from one of these planetoids to another.
Some animals have developed with the power to travel from one of these planetoids to another--like a squid jetting out water.
It also includes a number of moons or satellites revolving around the planets, a number of small bodies, called planetoids or asteroids, together with numerous comets and meteorites.
It is, however, admitted that the mutual perturbations of the planetoidsthemselves would suffice, in the course of some millions of years, to destroy all traces of a place of intersection of their orbits, if it once existed.
Moreover, considering the general relation between the inclination of planetoid orbits and their eccentricities, it is probable that among the orbits of these undetected planetoids are many of the most eccentric.
Nor when we consider the inclinations of the orbits do we meet with obvious verifications; since the proportion of highly-inclined orbits among the smaller planetoids does not appear to be greater than among the others.
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.
How happens this close kinship--how happens there to be this family of comets so much like the planetoids and so much like one another, but so unlike comets at large?
And they name themselves after the planetoids and other heavenly bodies," interjected Elodia, "because they live so near the stars.
I learned that nearly all Caskians are named after the planetoids or other heavenly bodies,--a very appropriate thing, since they live so near the stars!
After all, we have a million trading planetoidsout in the Galaxy--if we retreat here, we set a dangerous precedent.
I don't recall any alien trading planetoidsin our system.
No really satisfactory and final explanation of the present state of the planetoids has ever been given.
It is now thought probable that in the original nebula the matter forming the planetoids might have been prevented from condensing into a planet by the powerful gravitative influence of Jupiter.
At one time they had probably constituted a single planet, but some unimaginable explosion far back in time had scattered the great ball broadcast, and the largest of the resulting planetoids was now no more than 440 miles across.
We want to stay in the same relation to the planetoids till we decide where to look for Fawcett.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "planetoids" in a variety of sentences. We hope that you will now be able to make sentences using this word.
