WISE1810: An ancient brown dwarf in our cosmic neighbourhood


The recent study led by the Instituto de Astrofísica de Canarias (IAC) has revealed that the metal-poor brown dwarf WISE1810 (or WISE J181005.5-101002.3, according to International Astronomical Union standards) is only 29 light-years away, making it part of the immediate solar neighbourhood. The research has also determined that it has a cool surface temperature (525 °C), a luminosity a million times lower than that of the Sun, and a mass in the range of brown dwarfs. Its proximity and properties could suggest a possible overabundance of brown dwarfs formed in the early stages of the Milky Way.
