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

An asteroid is a minor planet —an object larger than a meteoroid that is neither a planet nor an identified comet —that orbits within the inner Solar System or is co-orbital with Jupiter (Trojan asteroids)

Asteroid, any of a host of small bodies, about 1,000 km (600 miles) or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt Hundreds of thousands of asteroids are known

What are asteroids? Asteroids are rocky objects that orbit the Sun just like planets do In fact, sometimes asteroids are called “minor planets ” These space rocks were left behind after our solar system formed about 4 6 billion years ago Asteroids are found in a wide range of sizes For example, one small asteroid, 2015 TC25, has a diameter of about 6 feet – about the size of a small

Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across

The objects in the asteroid belt never had the chance to be incorporated into planets They are leftovers from that time long ago when planets formed Are all asteroids the same? No way! Because asteroids formed in different locations at different distances from the sun, no two asteroids are alike Here are a few ways that they differ:
