Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).
Dwarf planet Pluto is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds, which formed early in the history of our solar system about 4.5 billion years ago.
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.
25 wrz 2019 · Pluto’s surface is quite varied, with large differences in both brightness and color. It is one of the most contrastive bodies in the Solar System, similar in contrast with Saturn’s moon Iapetus.
It was named by 11-year-old Venetia Burney of Oxford, England. Pluto nearly fills the frame in this image from NASA’s New Horizons spacecraft taken on July 13, 2015, when the spacecraft was 476,000 miles (768,000 kilometers) from the surface.
Pluto, along with it's largest moon Charon, are considered a double dwarf planetary system, and is sometimes referred to as the Pluto-Charon system. Charon is 51% the size of Pluto. Pluto's surface consists of 98% nitrogen ice with ice mountains, ice volcanoes, and has a thin atmosphere consisting of nitrogen and trace gases.
