Pluto is a dwarf planet beyond the orbit of Neptune. It was discovered in 1930, the first space object in the Kuiper belt. It was instantly called the 9th planet of the Solar system.

A Map of Every Object in our Solar System

Solar System appeared 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast bulk of the Solare system’s mass is in the Sun, with most of the remaining mass contained in Jupiter. This planet and Saturn are gas giants, mainly formed of hydrogen and helium; Uranus and Neptune are ice giants. The four smaller innermost planets, Mercury, Venus, Earth, and Mars, are terrestrial, being principally formed of rock and metal.
