Palauan , a few years back there was a mod that added a few more satellite galaxies of the milky way, have you thought about doing something similar that includes all the milky way satellites up to 2018 like Carina II and III?
don't forget Canis major dwarf! (which i'm surprised it's not already in spaceengine.)
I'm good when it comes to Physics, Algebra, Relativity, Space, and SpaceEngine. But I could still use a LOT of help on the things I still don't know. So I hope I get a lot of help on how all that works, here!
