Most asteroids orbit the sun within a broad belt located between the orbits of Mars and Jupiter: the asteroid belt. Millions of asteroids are under 0.6 mile (1 kilometer) in diameter, but there are many that are larger.
Phobos has the closest orbit to its primary of any moon in the solar system, but still only appears a third as wide as Earth's full moon. Phobos orbits only 3,700 miles (6,000 km) from the Martian ground. Its surface is marred by debris that may have come from impacts on Mars.
