Asteroids
Asteroids are star like heavenly bodies lying between Mars and Jupiter. The main asteroid belt lies as more than two or half times away from earth as the sun is away from our earth. Their sizes vary from small boulders to few thousand feet in diameter.
Asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. Near the beginning, the birth of Jupiter barred any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment them into the asteroids seen today. The main asteroid belt once contained enough material to form a planet that could be 4 times greater than the size of our earth but Jupiter gravity not only stopped the creation of such planet but kept them away to form planet. Composition indicates that majority of asteroids are formed of rock and stone containing iron and miracle and remaining asteroids are mixture of rock, stone and carbon containing material. These asteroids have atmosphere. The largest asteroid is Vesta. The main asteroid belt also contain planet Ceres which is the quarter of the size of our moon. These asteroids are irregular in shape and resemble lumpy potato. Asteroid216 Kleopetra resembles dog bone.
Mega asteroid is so big that it could trigger earthquake to skim past earth-volcanoes. Occasional collisions and gravitational pull send asteroids towards the sun on highly elliptical orbits and somewhat close enough to Earth to pose as a risk of impact. Astronomers are constantly on the lookout for bodies on such a terrible path. Most asteroids, fortunately, are too small to cause any damage. Instead they burn up in the atmosphere and appear to us as a shooting star.
