Luyten b
Distance: 12.2 Lightyears
Star: Luyten’s Star
Constellation: Canis Minor
Luyten b was discovered on March 17, 2017, using the radial velocity method, by Nicola Astudillo-Defru. This is a Super-Earth, but only about 2.89 times the mass of Earth. It also only sees around 6% more starlight compared to Earth. Thus, it is not too hot like other planets. Of course, its host star, Luyten’s Star, is a medium-sized red dwarf.
It’s essentially a very inactive star, making it less of a threat compared to other red dwarf stars. The spin rotation is on point with the planet, it likely contains water, and there does not seem to be any runaway greenhouse effect known. It is not shocking why it was listed as one of the most likely planets that could house human life one day. Luyten b is so well-liked that in October of 2017 & 2018, the organization Messaging Extraterrestrial Intelligence or METI sent a message containing several short musical compositions. They even sent a scientific tutorial that essentially gave our coordinates. If intelligent life is present on Luyten b, we’ll surely know one day.
