I am open for suggestions, what are you looking for!
A few suggestions: quasars, dark matter, pulsars, gamma-ray bursts, space stations (similar in size to existing moons so you can connect to a planet). And maybe another color variations of the previous celestial bodies :)
Good ideas, I will see what I can do!
Some quasars/pulsars and space stations have been added!
Wow thank you, you are awesome I really appriciate it ;)
