So what real-life/in-universe historical figures, deities, celestial bodies, physical phenomena, etc need a Starfleet starship (class) named for them? And although I can't and won't enforce such a rule, I mean that starships in random mass listings in RPG modules, video games, etc. can be used here but starships in novels, etc cannot. And let's try to limit the starships to about the late 24th century since there's a general like for Star Trek main cast characters and starships are generally not named for living persons. Here is my starting 5:
Amaterasu (the Japanese sun deity)
Edwin Hubble (the guy with the famous space telescope named for him)
James Webb (the guy whose eponymous space telescope will replace the Hubble telescope)
Quaoar (Kuiper Belt object in the Sol System; may qualify as a dwarf planet; named for a Native American deity)
Martin Luther King, Jr. (y'all should know who he is)
