Others are believed to be fragments from a collision of large asteroids or protoplanets. Comets are known to be remnants of the early solar system but their numbers

Where are asteroids found?

Overview Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles []

Why are there so many asteroids in the Solar System?

The asteroids are thought to be the result of disrupted protoplanets from the beginning of the solar system, probably due to the fact that they are so close to giant Jupiter and its intense gravity. They come in all shapes, sizes, and compositions and may hold keys to the early formation of the solar system over four and a half billion years ago.

Comets: Facts

Comet Facts In the distant past, people were both awed and alarmed by comets, perceiving them as long-haired stars that appeared in the sky unannounced and unpredictably. Chinese astronomers kept extensive records for centuries, including illustrations of characteristic types of comet tails, times of cometary appearances and disappearances, and celestial positions.

Solar System

The rest of the Solar System is its eight major planets, five dwarf planets, hundreds of moons, and a large number of comets, asteroids, and other small bodies of rock and ice.
