Pluto System: February 15, 2006
About the Object
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.Although its orbit is highly eccentric, Pluto's average distance from the Sun is 39.44 Astronomical Units (A.U.) or roughly 3.6 billion miles (5.9 billion kilometers).
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.Pluto has a diameter of roughly 1,416 miles (2,280 km) at the equator.

Hubble's Latest Look at Pluto's Moons Supports a Common Birth
This pair of NASA Hubble Space Telescope images shows the motion of Pluto's satellites between February 15th and March 2nd, 2006. Both images were taken through a red filter (F606W) using the High Resolution Channel (HRC) of the Advanced Camera for Surveys (ACS). During this...
Hubble Color Images of Pluto's Moons Support a Common Birth
These NASA Hubble Space Telescope images of Pluto were taken on March 2, 2006, using the High Resolution Channel (HRC) of the Advanced Camera for Surveys (ACS). The image on the left was taken through a blue filter (F435W), and the one on the right was taken through a red filter...
Schematic of the Pluto System
The new HST/ACS observations made on March 2nd reveal that all three of Pluto's satellites are neutrally colored, unlike reddish Pluto itself. Pluto's reddish color is believed to be due to reddening agents created by the effects of sunlight acting on its nitrogen and methane...
