Kerberos

Wednesday, November 20, 2019

Astronomers using the Hubble Space Telescope discovered a fourth moon orbiting the icy dwarf planet Pluto in 2011 while searching for rings around the dwarf planet. The moon was temporarily designated S/2011 (134340) 1 (and sometimes called P4) and was officially named Kerberos by the International Astronomical Union (IAU) in 2013.

Kerberos has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto's largest moon, is 648 miles (1,043 km) across, and two other moons of Pluto, Nix and Hydra, are in the range of 20 to 70 miles in diameter (32 to 113 km).

Kerberos is located between the orbits of Nix and Hydra, which Hubble discovered in 2005. Charon was discovered in 1978 at the U.S. Naval Observatory and first resolved using Hubble in 1990 as a separate body from Pluto.
