NASA’s Hubble Discovers Another Moon Around Pluto July 20, 2011 09:00 AM (EDT) Hubble Space Telescope’s keen vision has found yet another moon orbiting the distant, icy dwarf planet Pluto. This discovery expands the size of Pluto’s known satellite system to four moons. The tiny, new satellite — temporarily designated P4 — was uncovered in a Hubble survey searching for rings around the frigid dwarf planet.

This image provided by NASA combines two labeled images of the Pluto system taken by the Hubble Space Telescope’s Wide Field Camera 3 ultraviolet visible instrument with a newly discovered fourth moon P4 circled. NASA announced Wednesday, July 20, 2011 that the Hubble Space Telescope has found a fourth moon circling Pluto, which had been demoted from full planet to dwarf planet.

Percival Lowell founded the observatory in 1894 to look at Mars and other objects, and it has been the site of some major astronomical discoveries, including the first evidence the universe is expanding, Pluto and the rings of Uranus.
