Below: the frozen mud-planes of Pluto. Charon is visible in the sky. Charon is Pluto's largest moon and although much smaller than Earth's Moon it is also much closer to its parent planet and so appears about 6 or 7 times as large in Pluto's sky as the Moon does on Earth. Above...
1，charon，冥府渡神，卡隆；卡隆星，英 [ˈkɛːrən]，美 [ˈkɛrən]，Astronomers were excited by the discovery of Charon.天文学家们对冥卫一的发现兴奋异常. What about the scale of other solar system objects? Well, here are Pluto and Charon compared to the Earth and the Mo...
Finally, recent observations of the surface composition of Charon are discussed and compared with observations of other similarly sized icy bodies in the outer Solar System.BrownMichaelE.EBSCO_AspAnnual Review of Earth & Planetary SciencesBrown, M.E. 2002, Pluto and Charon: Formation, Seasons, ...
Figure 1: An approach movie I made comprised of LORRI images of a number of Charon rotations about Pluto, in the Plutocentric reference frame. The regions informally named Cthulhu Regio (dark region at the “bottom” of the Pluto image) and Tombaugh Regio (bright feature next to Cthulhu) co...
A giant impact origin for Pluto's small moons and satellite multiplicity in the Kuiper belt The two newly discovered satellites of Pluto (P1 and P2) have masses that are small compared to both Pluto and Charon-that is, between 5 x 10(-4) and 1 x 1... SA Stern,HA Weaver,AJ Steffl...
Astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface of Pluto's largest moon, Charon, using observations from the James Webb Space Telescope. These discoveries add to Charon's known chemical inventory, previously identified by ground- and space-based observations, that...
The images included all of the New Horizons LORRI observations between about 3.6 hours prior to closest approach and closest approach; the longest change detection search interval for both Pluto and Charon was about 3.2 hours. Each image was compared to all lower resolution images of the same ...

These solids populate a circumbinary disk in the Pluto-Charon orbital plane; a large fraction of this material lies within a "satellite zone" that encompasses the orbits of Styx, Nix, Kerberos, and Hydra. Compared to the narrow rings generated from the debris of a collision between a trans-...
