#2 It is locally convex in the sense that it has no loops
Re: Orbit of the Moon around the Sun
#3It is locally convex in the sense that it has no loops Of course it has loops. But in the scale of the drawing , the loops are lost due to the vast distance from Earth/Moon system to Sun.
It doesn't have any "lost" loops.

Can you also add Earth's orbit to the drawing?

Dude. You downvoted me for pointing that out? Seriously?

anvay could not have downvoted you, as your comment was a reply to them, so no, they didn't downvote you for that.

In other words, the path of the Moon is convex. By any common usage of the language, that means it has no loops.

I can't downvote anything yet, I am new :)
Yes the wired article is a better explanation(which btw I posted in a comment below). I was however struck by just the no loops part which you rightfully mentioned. It is so counterintuitive. But later I found that the moon is slower around earth than I had assumed(~27days), that was causing the problem for me.

Compare the speed of the Moon in orbit, relative to the Earth, which is about 1km/sec, whereas the Earth in orbit around the Sun is about 30 km/sec.

Are you saying that retrograde motion would not be observed from the Sun's perspective?
