Astronomers have discovered a "failed" star that can't sustain nuclear fusion in its core, but is 3,600 degrees Fahrenheit (2,000 degrees Celsius) hotter than the sun thanks to its proximity to a stellar companion.
The failed star, also known as a brown dwarf, sits about 1,400 light-years from Earth and orbits an entity called a white dwarf. White dwarfs are cooling remnants of sun-like stars that ran out of fuel at the end of their stellar lives.
