The dwarf planet Pluto has at least 10 known satellites. There is also a small system of rings of debris that has been recently detected.
Of the eight planets in our solar system, only Mercury and Venus have no known satellites. Furthermore, Pluto has at least four of them.
No, it is not true that Pluto has 7 satellites. Pluto actually has five known satellites which are Charon, Styx, Nix, Kerberos, and Hydra.
Mercury, Venus, Earth, Mars, Neptune and Pluto.
As of 2012, there are 4 known natural satellites (moons) of Pluto.Charon was discovered in 1978, Nix and Hydra in 2005, and the fourth moon, provisionally called S/2011P1, was found in 2011. Charon's diameter is over half that of Pluto, and the Pluto-Charon pair actually represent a co-orbiting binary system. Nix and Hydra are both much smaller, having diameters estimated at between 5% and 7% of Pluto's.There are no artificial satellites orbiting Pluto. The unmanned NASA probe "New Horizons" will pass near Pluto in 2015.
