Sorry if this doesn't belong in the AT forums, I just think it sounds advanced
I would like to know how to do an elliptical orbit for a circular object orbiting around another object.

If the ellipse can be stretched only on the x or y axis, try:

forever
    set [i v] to [1]
    repeat (360)
        go to x:((center-x) + ((x-radius) * ([cos v] of (i)))) y:((center-y) + ((y-radius) * ([sin v] of (i))))
        change [i v] by (1)
    end
end

If you need something more complicated than that, you could try looking up “parametric equation of an ellipse,” although I'm sure I've seen some orbit projects around here and you could probably steal the code from there.

Okay, I'll test it out soon.

Like so: https://scratch.mit.edu/projects/56127958/

(Literally a 2 minute hack to remix)

I won't be on the computer again for about 14 hours.

Here's one that lets you change the orbit parameters mid-orbit: https://scratch.mit.edu/projects/56143060/

You might check out my orrery project here.

(Is this still relevant?)

Sure
