This looks really good.
I would appreciate a close button on the docking screen, and a button to return to the galactic view instead of having to press the ESC key.
Also maybe try to make the planets have a certain radius around them, in which other planets can't spawn, I got a couple of clusters of very close planets.
The animation and of the ship looks smooth and the planets and stars also have good variance but also a good level of detail.
Overall I really like it! Congrats on the release and keep it up.
