NASHVILLE, Tenn. (CNN) — Scientists have determined that a distant dwarf planet is much bigger than initially thought.
According to NASA, it’s known as “2007 or10,” and astronomers say new data shows it is the third largest dwarf planet on a list of a half a dozen worlds.
Finding dwarf planets is a difficult task, but NASA’s planet-hunting space telescope, Kepler, helped astronomers revise the size of the planet.
Scientists also used data from the European Space Agency’s Herschel Space Observatory mission.
“2007 or10” is 955-miles in diameter, about one-third Pluto’s size.
Scientists say it is a very dark world, likely left over from when the sun and solar system first formed.
The astronomers who discovered the planet will give “2007 or10” a name.
