Washington, DC—Carnegie’s Scott Sheppard and his colleagues—Northern Arizona University’s Chad Trujillo, and the University of Hawaii’s David Tholen — are once again redefining our Solar System’s edge. They discovered a new extremely distant object far beyond Pluto with an orbit that supports the presence of an even-farther-out, Super-Earth or larger Planet X.

The planet’s name was Pluto and its discovery culminated the search begun by Percival Lowell for Planet X — a theoretical new member of our solar system. Last week, a team of astronomers including NAU’s Chad Trujillo announced their own startling discovery while carrying out a modern Planet X… Read more
