Incredible work! My son really had a blast scrolling around and exploring last night.
Did you take any inspiration from Celestia (https://celestiaproject.space)? It's been over 15 years since I last really used it (and starts with defaults not geared towards visualizing just our local solar system) but seems to have a lot of the features others have suggested. Might be useful to poke around and see how they solved things like time adjustments, selecting POIs, etc.
Hey, thanks! I hadn't seen Celestia until another commenter mentioned it. Cool project, definitely some UX cues to take from it like the progressive hiding of labels and ellipses as you zoom out.
