Most asteroids can be found
WebAsteroids are rocky and metallic objects that orbit the Sun, and that come in all kinds of shapes and sizes. Ceres, the biggest, contains about one-third of the mass of all the asteroids in our solar system. The smallest asteroids are larger than 1 meter (a little over 3 feet). Objects smaller than 1 meter are called meteoroids. WebApr 5, 2002 · The ISO Deep Asteroid Search indicates that there are between 1.1 million and 1.9 million 'space rocks' larger than one kilometre in diameter in the so-called 'main asteroid belt', about twice as many as previously believed. However, astronomers think it is premature to revise current assessments of the risk of Earth being hit by an asteroid.
