Astronomers have discovered one of the sun's neighbors - a brown dwarf star which is as frosty as Earth's Arctic.
Penn State University astronomers believe the brown dwarf is the coldest of its kind, writes Science World Report.
The star, named WISE J085510.83-071442, was found 7.2 light years away making it the fourth closest neighbor to our Sun.
It was discovered using NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes.
"It is very exciting to discover a new neighbor of our solar system that is so close," said Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State and a researcher in the Penn State Center for Exoplanets and Habitable Worlds.
