For the first time, scientists have been able to measure the wind speed on an object outside of our solar system, according to a new study. The object, known as a brown dwarf, is 33.2 light-years away from Earth.
Brown dwarfs aren't quite stars, but they're not planets either. These so-called"failed stars" are too big to be planets. The brown dwarf in this study is the size of Jupiter, the largest planet in our solar system, but it has 40 times the mass of Jupiter. On the nearby cool brown dwarf 2MASS J1047+21, scientists clocked wind speeds reaching 1,450 miles per hour. The study published Thursday in the journal Science.
'Failed star' displays powerful auroras, experts say"Even though brown dwarfs are completely covered in clouds, they're too far away for us to pick out individual clouds like we do on planets within our solar system. But we can still measure how long it takes for a group of clouds to do a lap around the atmosphere; as clouds come in and out of view they change the brightness of the planet," Williams said.
