I find a lot of "space" names very clunky. Nebula,
Vega,
Andromeda,
Nova,
Lyra,
Carina,
Orion .... they all just thump along, like something falling down the stairs. They're so blunt and unmusical.
My favourite astronomy name is probably
Adhara, which is still pretty thump-y, but I find it satisfying.
