How many moons does Pluto have?

Answer 1

Phobos, the inner of Mars' two natural satellites, is in spin-orbit resonance, and

like Earth's moon, its axial rotation and orbital revolution periods are equal.

The period is 7hours 39.2minutes

Answer 2

Pluto has five known moons:

1. Charon, the largest one, Charon was discovered in 1978.
2. Hydra, very small
3. Nix, very small, and two more-newly discovered small moons. and Nix/Hydra were identified in 2005.
4. Kerberos (provisionally named P4 or S/2011-134340)
5. Styx (S/2012-134340). On July 11, 2012, it was announced that a team of astronomers, using NASA's Hubble Space Telescope, discovered a fifth moon orbiting Pluto. The moon is provisionally designated as S/2012 (134340) 1. The moon was discovered by astronomers using nine sets of images taken by the Wide Field Camera 3 fitted to the Hubble Telescope between June 26, 2012 and July 9, 2012. It is estimated to be an irregular shape and 6 to 15 miles across.

The largest moon, Charon, is proportionally larger compared to its primary than any other satellite of a known planet or dwarf planet in the solar system. In fact there is some discussion as to whether we should consider this a "binary system" instead of a dwarf planet with moons because Charon is so massive that the barycenter (center of gravity around which the bodies rotate) of the Pluto-Charon group is not inside either of those bodies.

Answer 3

The Moon's diameter is 3,474 km, just over a quarter that of the Earth.

Answer 4

Pluto has five known moons: Charon, Styx, Nix, Kerberos, and Hydra.

Answer 5

The Earth's moon is approximitaly 3,474 kilometers in diameter.

Answer 6

Phobos is one of the two moons of the planet Mars. It has the dimensions 27 x 22 x 17 km.

Answer 7

The adverage diameter of Mars's moon Deimos is 14Km.

Answer 8

Phobos and Deimos are the two moons of Mars.

Answer 9

The moon Phobos, along with the moon Deimos, orbit planet Mars.

Answer 10

Like many small objects, Phobos has an irregular shape. The Wikipedia lists its size as 27 x 22 x 18 km.
