Charon, Pluto, TNOs

TNOsEightTNOsCharon compared with Eris, Pluto, Makemake, Haumea, Sedna, Orcus, 2007 OR10, Quaoar, their moons and Earth. All to scale.

The center of mass (barycenter) of the Pluto–Charon system lies outside either body. Because neither object truly orbits the other, and Charon has 11.6% the mass of Pluto, it has been argued that Charon should be considered to be part of a binary system. The International Astronomical Union (IAU) states that Charon is considered to be just a satellite of Pluto, but the idea that Charon might be classified a dwarf planet in its own right may be considered at a later date.

New Horizons Reveals Ice Mountains on Pluto

By JONATHAN CORUM JULY 15, 2015

A day after its successful flyby, NASA’s New Horizons spacecraft sent back the first close-up photographs of Pluto, revealing a young surface dotted with ice mountains. The piano-size spacecraft traveled nine years and three billion miles to study the dwarf planet and its five moons.

Ice mountains up to 11,000 feet high — comparable to the height of the Rockies — cast shadows across a relatively smooth plain. The lack of craters indicates that the surface is quite young, no more than 100 million years old. This photo was taken early on Tuesday morning and shows an area just under the bright heart shape on Pluto’s surface.
