New evidence suggests a ninth planet lurking at the edge of the solar system

Washington Post:

Astronomers at the California Institute of Technology announced Wednesday that they have found new evidence of a giant icy planet lurking in the darkness of our solar system far beyond the orbit of Pluto. They are calling it “Planet Nine.”

Their paper, published in the Astronomical Journal, describes the planet as about five to 10 times as massive as the Earth.

Planet Nine! Sounds like a good name for a Pixar movie.

Sorry, Pluto, you’ve been replaced.
