What planets have an asteroid belt?
There aren't any planets within our solar system that have an asteroid belt themselves. There is, however, an asteroid belt located between the orbits of Mars and Jupiter.
The solar system can be divided in two parts, by the asteroid belt. The planets that are closer to the sun than the asteroid belt are Mercury, Venus, Earth, and Mars. These are the inner planets. The planets more distant from the sun than the asteroid belt are Jupiter, Saturn, Uranus, and Neptune. Those are the outer planets. And even farther out are the dwarf planets and comets.
