Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.

When New Horizons arrived at Pluto, it measured the diameter of the world to be 1,473 miles (2,370 kilometers) across, about two-thirds the diameter of Earth's moon. This makes it larger than the dwarf planet Eris, once thought to be larger than Pluto. Eris is 1,445 miles (2,326 km) in diameter. "This settles the debate about the largest object in ...
Although all of the planets beyond Mars are gas giants, Pluto is small and rocky. The tiny body has a mass of only 1.31 x 1022kilograms, about two-tenths of a percent of Earth's. It has a volume of 1.5 billion cubic miles (6.4 billion cubic km). Pluto's small size and low mass mean that it has a density of 1.86 grams per cubic centimeter according ...
Since its discovery in 1930, Pluto's status as a planet has been debated. It is less massive than seven of the moons in the solar system — Earth's moon, the four Galilean moons of Jupiter, Neptune's moon Triton, and Saturn's moon Titan. [Infographic: Pluto's 5 Moons Explained] In 2003, the icy body of Eris was found far beyond the Kuiper Belt. Orig...
Pluto's surface is characterized by mountains, valleys, plains, and craters. The temperature on Pluto can be as cold as -375 to -400 degrees Fahrenheit (-226 to -240 degrees Celsius). Pluto's tallest mountains are 6,500 to 9,800 feet (2 to 3 kilometers) in height.
