Dwarf star lurks in close proximity to the sun

Dimly glowing, unseen in the interstellar void lurks a newly discovered Dwarf star.  A Y dwarf that is much cooler than most known stars, it barely reaches room temperature.  It is 9 light-years distant from us – meaning that the dim light we receive from it is less than a decade old.

It was discovered by NASA’s Wide-field Infrared Survey Explorer (WISE) mission – which has also revealed many more Y dwarfs further afield.
