Freebase

  1. Asteroid

    Asteroids are minor planets that are not comets, especially those of the inner Solar System. They have also been called planetoids, especially the larger ones. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids. Thus the term asteroid has come increasingly to refer specifically to the small bodies of the inner Solar System out to the orbit of Jupiter. They are grouped with the outer bodies—centaurs, Neptune trojans, and trans-Neptunian objects—as minor planets, which is the term preferred in astronomical circles. In this article the term "asteroid" refers to the minor planets of the inner Solar System. There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter or co-orbital with Jupiter. However, other orbital families exist with significant populations, including the near-Earth asteroids. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, S-type, and M-type. These were named after and are generally identified with carbon-rich, stony, and metallic compositions, respectively.

Examples of Asteroid in a Sentence

  1. Ed Lu:

    There is about to be an awful lot more data and observations on asteroids, we're preparing for this flood of data. Together with our partners, we are working to understand how well we are going to be able to determine if an asteroid is going to hit the Earth. More observations means less uncertainty.

  2. Professor Fitzsimmons:

    We will get a serious asteroid impact sometime, it may not be in our lifetime, but mother nature controls when that will happen.

  3. Ian Miller:

    Were it not for the asteroid, humans would never have evolved, one message I would like people to take from this is that their earliest ancestors - and by ancestors we're talking fuzzy little squirrel-like critters - had their origins in the wake of the extinction of the dinosaurs.

  4. Felipe Alves:

    We see two compact sources that we interpret as circumstellar disks around the two young stars, the size of each of these disks is similar to the asteroid belt in our Solar System and the separation between them is 28 times the distance between the Sun and the Earth.

  5. Paul Chodas:

    I suspect this newly discovered object 2020 SO to be an old rocket booster because it is following an orbit about the Sun that is extremely similar to Earth's, nearly circular, in the same plane, and only slightly farther away the Sun at its farthest point, that's precisely the kind of orbit that a rocket stage separated from a lunar mission would follow, once it passes by the Moon and escapes into orbit about the Sun. It's unlikely that an asteroid could have evolved into an orbit like this, but not impossible.
