NASA’s Hubble Helps Find Moon Around Third Largest Dwarf Planet In The Solar System

The largest unnamed body in the solar system, a dwarf planet provisionally called 2007 OR10, has been found to have a moon of its own. The discovery was made using data from three space telescopes, including Hubble, NASA’s Kepler and the now inactive Herschel Space Observatory (HSO) which was operated by the European Space Agency (ESA).
