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... - Source: Hacker News / over 1 year ago

There are of course notable exceptions like Barnard's Star, whose movement is pretty obvious on photographs taken over several decades. If you want to explore how space changes over time, I recommend you look into... - Source: Hacker News / about 2 years ago
