The correct option is A is a planet that does not orbit the Sun and instead orbits a different star or brown dwarf.
Asteroids are rocky, airless worlds that orbit our sun, but are too small to be called planets. Tens of thousands of these minor planets are gathered in the main asteroid belt, a vast doughnut-shaped ring between the orbits of Mars and Jupiter. Asteroids that pass close to Earth are called near-earth objects. Superior planets are the planets whose orbits lie outside Earth's orbit around the Sun: Mars, Jupiter, Saturn, Uranus, Neptune, and, historically, the former planet Pluto.
