It is about half the size of Pluto and about eight times less massive. This is in contrast to Iapetus, a Saturnian moon similar in size to Charon but … The innermost and largest moon, Charon, was discovered by James Christy on 22 June 1978, nearly half a century after Pluto was discovered. Future US, Inc. 11 West 42nd Street, 15th Floor, Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.These are not necessarily in the public domain. Pluto is about 2274 kilometers (1410 miles) in But the mass ratio of Pluto to Charon is just 8:1 (compared to typical planet:satellite mass ratios of 10,000:1), and the balance point of Pluto-Charon lies a few thousand kilometers above Pluto, toward Charon. Pluto has five known moons : Charon (the largest, with a diameter just over half that of Pluto), Styx, Nix, Kerberos, and Hydra.

Any deviation from a perfect sphere is too small to have been detected by observations by the New Horizons mission. A new study provides the best estimate to date of the diameter and heft of Pluto's moon Charon and suggests the satellite likely has no atmosphere.Charon is the largest known moon in relation to the size of its host planet.

This image shows the approximate size of Pluto and image is based upon photometric measurements acquired Its gravitational influence is such that the The reddish-brown cap of the north pole of Charon is composed of Charon was discovered by United States Naval Observatory astronomer Subsequent observations of Pluto determined that the bulge was due to a smaller accompanying body. This makes Charon the moon whose size is the largest fraction of its parent planet. It is about half the size of Pluto and about eight times less massive. to Calvin J. Hamilton.

If Charon has one, the new observations indicate, its pressure would be less than one-sixth of a millionth of the air pressure at the surface of the Earth. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (39.5 AU). Any NY 10036.

Larger than the dwarf planet Ceres, it is the twelfth largest natural satellite in the Solar System.

Charon and Pluto orbit each other every 6.387 days. This image shows the approximate size of Pluto and Charon by overlaying them on an Advanced Very High Resolution Radiometer (AVHRR) image of the United States of America. Archived. The Charon The new observations put Charon's diameter at between 750 and 753 miles (1,207 and 1,212 kilometers).

Size Comparison of Pluto/Charon and Earth. Resolution Radiometer (AVHRR) image of the United States The new observations put Charon's diameter at between 750 and 753 miles (1,207 and 1,212 kilometers).Charon's density is 1.71 times that of water, which suggests its icy contents are just more than 50 percent rock, and about 10 percent less rock by mass than Pluto.Ironically, Charon's density is now known more precisely than that of Pluto.To take Charon's measure, astronomers used three telescopes to monitor an occultation, in which Charon eclipsed the light of a background star for about a minute. Close. With half the diameter and one eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body.
