Dutchman- Did you see the replies here? And my posting under this topic (BASIC Programs) ? (You indicated interest in it.)

As to simulation: The discussion reminds me of something i programmed years ago:
The simulation of "Four celestial bodies attracting each other"

Sounds interesting. Does it use the same “incremental changes” method? Or does it use actual equations? I have never tried 4, only 3 (Sun, Moon, & Satellite). I also made it work as Earth, Moon, & the Artemis II recent loop around the moon. I can post it if you’re interested.
