Speaking of planet lore
Sirius is Venus destroyed by global warming
Bellatrix I can see being Saturn, losing its rings
Regulus was to an heir, he failed too just as Jupiter failed to be a star
James, alone, carries the burden of providing life, SUNny boy
Like Pluto, Peter is too small to be part of the group
Earth(Remus) is slowly destroying itself.
Even mars once had water on its surface. McGonagall at 60 with white hair ):
Mercury, the forgotten planet/Mary MacDonald who obligated herself
The moon needs the sun to shine, it's dark without it. Wolfstar
Neptune is slowly moving away from the solar system, Andromeda
Uranus used to be closer to the sun but with the arrival of the other planets, moved away. James and Peter
Owl nebula thought she was just a planet but she was so much more than that. Dorcas Meadows scared Voldemort so much, he personally had to kill her
When the sun can't hold its weight, it explodes. War James
This is entertaining though, I could do candy lore-
