A and B, the brown behemoth's legacy
The Luhman 16 is no might of nature.
Not in relativity. The mass of A is only .03 Solar Mass, while B is .04 Solar Mass.
Its temperature is also relatively low due to the lack of solar fission, at 1210 kelvin.
Along with everything else, it gives no new light or luminosity.
The origin of Luhman 16 dates back to Eric E. Mamajek.
And among everything, its original name is much longer than you'd expect, being named firstly WISE J104915.57−531906.1
But why a brown dwarf?
Stars like these closely resemble planets because they undergo fission, but instead of exploding or compressing further, they reach stability and stay in that state.
