    Well this does move the particle in a circular orbit, but they're moving away bit by bit over time, which ends up like a ripple-like spiral. The result I'm looking for is a perfect round orbit. Is there a way to make it?

    Hi @Happy_Face ,

    You can use the Rotate2D or Rotate3D nodes to do something like this:

    * Please note that the angle is in radians.

    The result would be something like this:


    Hope this helps!

    Back when the forum gods thought all VFX graph questions were best organised via a single 2 trillion page mega-thread there was some discussion of orbital velocity. You can probably find it via search.
