The exoplanets of TRAPPIST-1 are rocky worlds that orbit close to their red dwarf star, and at least three are in the habitable zone. Could they support life?
(−1.46 apparent magnitude), Canopus (−0.86) and Alpha Centauri (−0.27). However, Alpha Centauri is a binary star, whose unresolved components to the naked eye are both fainter than Arcturus. This makes Arcturus the third-brightest individual star, just ahead of Alpha Centauri A, whose...
