Farout: Scientists spot solar system's farthest known object
Astronomers have spotted the farthest known object in our solar system - and they've nicknamed the pink cosmic body "Farout."
The International Astronomical Union's Minor Planet Center announced the discovery Monday.
"Farout" (pronounced far-out) is about 120 astronomical units away - that's 120 times the distance between Earth and the sun, or 11 billion miles. The previous record-holder was the dwarf planet Eris at 96 astronomical units.
The Carnegie Institution's Scott Sheppard says the object is so far away and moving so slowly it will take a few years to determine its orbit. At that distance, it could take more than 1,000 years to orbit the sun.
The astronomers spied the dwarf planet in November using a telescope in Hawaii.
It's an estimated 500 kilometers (310 miles) across.
