Could Pluto Have 15 Moons?

Today is the 83rd anniversary of the announcement of Pluto's discovery by the Lowell Observatory. The date was chosen because it is the birthday of Percival Lowell, who first started the search for a Trans-Neptunian planet and founded the Lowell Observatory, and because it is the anniversary of the discovery of the planet Uranus by William Herschel in 1781. Significantly, Herschel first thought his discovery was a comet because no one could conceive of the idea of planets beyond Saturn.

This anniversary is an especially appropriate time for the latest research on Pluto, which shows that the small planet may have up to 10 more moons, which could bring its total number of moons to 15! More information can be found here: http://www.space.com/20181-pluto-moons-new-horizons.html
