Astronomers observe the best-known object in our solar system


Astronomers have identified the farthest object known in our solar system – and they have nicknamed the pink cosmic body of "Farout."

The Minor Planet Center of the International Astronomical Union announced the discovery Monday.

"Farout" stands at about 120 astronomical units, which is 120 times the distance between Earth and Sun, or 18 billion miles. The previous record holder was the dwarf planet Eris in 96 astronomical units.

Scott Sheppard of the Carnegie Institution says the object is so far away and moving so slowly that it will take a few years to determine its orbit. At this distance, it may take more than a thousand years to orbit the sun.

Astronomers saw the dwarf planet in November using a telescope in Hawaii.

It is estimated at 500 kilometers in diameter.
