PLUTO

Pluto has long been considered the Solar System's 9th planet, but recent research allowed it to be named more as a "dwarf" planet rather than an official planet. There exists a belt much like the asteroid belt between Mars and Jupiter, called the Kuiper Belt outside Neptune, in which Pluto resides. Its makeup consists of ice, rock, methane, and nitrogen. It also rotates in retrograde motion like Uranus and Venus. Its looks suggest a likeness to early Roman views of the underworld, and hence got its name from the appropriate god, Pluto.
