  1. Asteroids are formed when you sit on cold concrete steps... No wait that's hemorrhoids.


  2. Asteroids are simply rocks made when the solar system formed out of a condensing cloud of dust and gas.

    They were not accreted by planets and they did not have sufficient gravity to form into a round mass. There were many following the creation of the solar system as planetoids and smaller orbs crashed into one another. Most of those have since crashed into the planets and moons which exist today. The ones which are left are mainly located in the asteroid belt between Mars and Jupiter. Gravitational perturbations can cause them to carreen out of their normal orbital paths and collide with each other. This is the only way that any new asteroids can form. The bits and pieces leftover from the collision of two asteroids which already exist.

    Comets which collide with planets and moons can throw materials into space but this material would mostly be composed of smaller matter than the larger asteroids. These would become meteoroids instead of asteroids.

  3. they are formed by moving dust and are then merged as one(asteriods). the asteriods are formed in a similiar way of how the earth was first formed...

  4. Asteroids were formed at the same time as the planets, roughly 4-5 billion years ago. They are leftover debris that was never swept up by accretion during the formation of planetoids. Asteroids in our solar system are no longer being formed, unless they happen to collide, and new ones are split off of a parent body. This process will obviously always result in smaller objects than the parents.

  5. Asteroids, also called minor planets or planetoids, are Solar System bodies smaller than planets but larger than meteoroids (which are commonly defined as being 10 meters across or less),[1] and that are not comets. The distinction between asteroids and comets is made on visual appearance when discovered: comets must show a perceptible coma (a fuzzy "atmosphere"), while asteroids do not.

    Asteroids vary greatly in size, from a few hundreds of kilometres in diameter down to rocks just tens of metres across. A few of the largest are roughly spherical and are very much like miniature planets. The vast majority, however, are much smaller and are irregularly shaped. The physical composition of asteroids is varied and in many cases poorly understood. Some are solid rocky bodies, with a greater or lesser metallic content, while others are piles of rubble held together loosely by gravity. Only one asteroid—Vesta—is visible to the naked eye, and this only in very dark skies when it is favourably positioned.

    The first named minor planet, Ceres, was discovered in 1801 by Giuseppe Piazzi, and was originally considered a new planet.[2] This was followed by the discovery of other similar bodies, which with the equipment of the time appeared to be points of light, like stars, showing little or no planetary disc (though readily distinguishable from stars due to their apparent motions). This prompted the astronomer Sir William Herschel to propose the term "asteroid", from Greek αστεροειδής, asteroeidēs = star-like, star-shaped, from ancient Greek Aστήρ, astēr = star.

    The vast majority of known asteroids are found within the main asteroid belt, between the orbits of Mars and Jupiter, generally in relatively low-eccentricity (i.e., not very elongated) orbits. This belt is estimated to contain more than 750,000 asteroids larger than 1 kilometer across, and millions of smaller ones.[3] It is thought that these asteroids are remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the solar system was prevented by large gravitational perturbations by Jupiter. Some asteroids have moons or are found in co-orbiting pairs known as binary systems. Minor planets have more recently been found to cross the orbits of planets, from Mercury to Neptune—with hundreds of trans-Neptunian objects (TNOs) now known to exist well past Neptune's orbit. (Using indirect methods, the total number of TNOs has been estimated in the hundreds of millions or even billions.)

    Asteroids are given a provisional designation by year in the order of discovery, and a designation (a sequential number) and name if their existence is well established and an orbit has been determined.

  6. There is no theory about asteroids, they are rocks which come of wondering comets
