Asteroids. Illustration of a group of asteroids orbiting the Sun (at centre) which is surrounded by a halo. Asteroids are lumps of rock or small planets that have elliptical orbits around the Sun. Most of these lie between the orbits of the planets Mars and Jupiter, an area known as the asteroid belt. The asteroids here have an irregular shape, indicating that they have a diameter of less than 160 kilometres. This is the most common asteroid size range, although the largest asteroids can be over 1000 kilometres in diameter.
