A brown dwarf that’s as frosty as the Earth’s North Pole has been discovered lurking incredibly close to our Solar System. Astronomer Keven Luhman from Pennsylvania State University used NASA’s Wide-field Infrared Survey Explorer (WISE) and the Spitzer Space Telescope to pinpoint the object’s temperature and distance. This is the coldest brown dwarf found so far, and it’s a mere 7.2 light-years away, making it the seventh closest star-like object to the Sun.

“It is very exciting to discover a new neighbor of our Solar System that is so close,” said Luhman in a press release.

Brown dwarfs emerge when clouds of gas and dust collapse. But unlike stars, they never grow dense enough or burn hot enough to ignite nuclear fusion in their cores. They live their lives less massive than stars, but more massive than gas giants. So they burn hot at first, then cool over time. And this newly discovered brown dwarf is as cold as ice. Literally.

"Luhman found the brown dwarfs temperature to be between –54° and 9° Fahrenheit (–48° to –13° Celsius).

So how do we warm it up? And how bad is the gravity going to be.

With a mass of only 3-10 Jupiters, it may not even qualify as a brown dwarf. There are exoplanets larger than that. But no one has really set any rules yet.

Seventh closest at 7 light years distant? What are the other six? (Are they counting the gas giants in our system?)

>> Brown dwarfs emerge

When they emerge from their burrow if they see their shadow there’s six more weeks of winter.

The proper plural form of dwarf is dwarves.

Yep. Look what they did to Pluto. Will always be a planet in my heart.

Wondering how long they’ll be able to keep that icon, what with all this PC and stuff. Just need one dwarf to complain.

I think these would be the 6 mentioned.

Luhman 16 A&B - 6.5 LY
WISE 0855–0714 - 7.2 LY
WISE 1506+7027 - 11.1 LY
(Epsilon) Indi A&B - 12 LY

There will likely be more found closer as time goes by.

The article was referencing Brown dwarf ‘stars’.
