Capella Aa and Ab are both very formal and gentlemen like. They're close with the second pair of stars, Capella H and L. Both Capella Aa and Ab are bright yellow giant stars, being more massive and larger than the Sun, as well as more luminous. Capella H and L are both M-Type red dwarf stars, and they orbit about 10,000 AU from Capella Aa and Ab. They are also close with Capella Aa and Ab, often talking very highly of them. Both red dwarfs like to goof around a lot. All stars are females.
