Beautiful. Reminds me of Stellarium, also open-source: <a href="https://github.com/Stellarium/stellarium">https://github.com/Stellarium/stellarium</a><p>As I kid I spent <i>hours</i> pretending to be Sulu at the helm of the Enterprise while flying through a field of stars. :) Good times.
Wow, I am truly impressed. Great work! I'll be donating to help this effort.
This has already been incredibly helpful to me and my son who is learning about the solar system. Being able to see the orbits of each planet in such a fantastic UI makes it a cinch to understand why Pluto takes turns being the most outer planet.<p>It's a Progressive Web App, uses Godot, so there's nothing to install; it's just a web page!
Very cool. Some small criticism/feedback:<p>- Pluto is shown as if it is spinning around itself, but in reality Charon (its largest moon) is so heavy (12.2% of Pluto) that their barycentre (<a href="https://en.wikipedia.org/wiki/Barycenter_(astronomy)" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/Barycenter_(astronomy)</a>) is actually outside of Pluto's surface.<p>- All the planets and moons are shown as perfectly spherical, but for the smaller ones (e.g. Charon) that's not accurate. Not sure if there is a practical way to fix this though.<p>- Zooming using the scrollwheel is backwards -- rolling the scroll wheel up zooms out, but in all other applications on my system it zooms in.<p>- The panels are very annoying. They can be hidden by unticking in the top right corner, but they still come back on mouseover (getting in the way when trying to click on a planet). I can't find a way to completely close them; they can be moved around, but they refuse to go offscreen. "Options > GUI Size> Small" helps a little.
Great project. I loved the idea of Visible Solar System on the Commodore VIC-20, but the execution was a bit limited by the technology 40 years ago to say the least.

Lovely! Learnt about the Hildas.<p>One possible bug (??): when looking down on the system (press the system button on the bottom centre panel, 90 degrees to the ecliptic) the orbit of pluto will be projected to cross or not cross that of neptune depending on which side of the system you look down from.
Not on desktop, but is this similar to NASA's Eyes?<p><a href="https://eyes.nasa.gov/" rel="nofollow noreferrer">https://eyes.nasa.gov/</a>
