Based on @owlygem‘s celestial body universe. Sirius B! (ty gemma for helping me hone his character down lol)

Twin brother of Sirius A, long ago they two were almost identical in personality and looks. Now a white dwarf star, he’s much smaller and more chill nowadays (Strong type B personality hurrhurrhurr), now much more open-minded. He doesn’t like making very many appearances in his star form anymore, preferring to fade in the background. He still loves his brother of course, though he can be a bit manipulative around him.

He spends much of his retirement time on earth’s beaches, and tends to call everyone “my dude.”
