Pluto
Pluto is a dwarf planet located in the Kuiper Belt, a region of the outer solar system beyond the orbit of Neptune. It was discovered in 1930 by Clyde Tombaugh and was considered the ninth planet in our solar system until 2006 when it was reclassified as a dwarf planet by the International Astronomical Union (IAU). Pluto has a diameter of approximately 1,470 miles (2,370 kilometers) and is composed mainly of rock and ice. It has five known moons, the largest of which is Charon, which is about half the size of Pluto. Pluto has a highly elliptical orbit that takes it as close as 4.4 billion miles (7.1 billion kilometers) and as far as 7.4 billion miles (11.9 billion kilometers) from the Sun, and it takes about 248 Earth years to complete one orbit.
