At the distance of Pluto, the Sun appears about 1000 times fainter than on Earth. Pluto has an eccentric orbit averaging some six billion kilometres from the Sun. After its discovery in 1930 Pluto was considered the ninth planet, but the discovery of numerous objects of similar or larger size led to its reclassification as a dwarf planet in August 2006..
