Scientists may have discovered the speed limit for a brown dwarf rotation

Brown dwarfs are also known as failed stars and can spin at extremely high velocities. Scientists know that a brown dwarf can spin as fast as 200,000 mph, but researchers believe there may be a limit to how fast they can rotate. NASA scientists have used data from the Spitzer Space Telescope to identify the three fastest-spinning brown dwarf stars ever discovered.
The three brown dwarfs are believed to be approaching a spin speed limit for all brown dwarfs. If they spun any faster, researchers believe they would break apart. The trio of fast rotating brown dwarfs are all roughly the same diameter as Jupiter but between 40 and 70 times more massive. Each of them rotates completely once each hour.
