how to add planet ceres in astronomy.js? #349

Closed testori1972 closed 2 months ago

testori1972 commented 3 months ago

I want to modify astronomy.js and astronomy.ts, I want to know how to calculate the planet Ceres and what various websites?

There is probably an algorithm for the 4 major asteroids somewhere. I would start by looking at Stellarium to see how they do it.

Yes, don't forget to include a tutorial on how to calculate the formula for 4 asteroid bodies so you can make more planetary bodies, and now I have to learn a lot about Blender to render to ThreeJS then render to HTML, CSS and JS
