New moons of Pluto. Artwork of Pluto (brown, centre right) and its large moon Charon (right of Pluto), seen from the surface of one of its two smaller moons, discovered in late 2005. The other new moon is the bright object at lower left. The moons were discovered through observations with the ACS instrument on the Hubble Space Telescope. Initial views of Pluto and Charon did not have sufficient exposure time to detect the other, far fainter, moons. Longer exposure images revealed the moons in May 2005. Pluto has an eccentric orbit around the Sun, with its distance varying between and billion kilometres. The discovery of objects larger than Pluto beyond Neptune has cast doubt on its status as a planet.
