Pretty good so far! If I were to make improvements, I'd add terrain on all objects with rocky surfases and perhaps find high quality textures for the planets.

where is the rocks on moon?

i made the textures in gprojector so if i add more celestial bodies then you know, and no moons on the moon cuz if they were there then they would be useless cuz i dont know how to code with thyme, so yeah its still good yet rough at the same time

rocks on the moon*

For the terrain, use the brush tool (autoglue off), adjust the slider, hold left mouse to draw, fill the geometry up using the same tool, use the erase tool if you want to add more detail and use the cut tool to separate layers (like glaciers) and glue it to the planet (using glue to ____, not fixjoint).

Otherwise, pretty understandable.
