A little-known oddity in the universe are ‘brown dwarfs’ – astronomical objects that are not quite stars or planets.
Brown dwarfs are called ‘failed stars’ since they’re more massive than planets but unlike stars they don’t have sufficient mass to sustain nuclear fusion in their cores.
Now, researchers have found the hottest known brown dwarf yet, hotter even than our own sun and located 1,400 light years away.
Called WD0032-317B, the object reaches around an impressive 8,000 Kelvin (7,727°C or 13,940°F) because it orbits so close to its star.
As a comparison, the surface temperature of our sun is approximately 5,778 Kelvin (5,498°C or 9,930°F).
A brown dwarf is a mysterious object that sits somewhere between a gas giant planet and بول ماشین a small star, but without the size to fuse hydrogen like a star would
Brown dwarf WD0032-317B is also up to 88 times the mass of Jupiter – making it one of the most massive brown dwarfs known, as well as the hottest.
