Trying to move static mesh in matinee

I have a static mesh I want to move, it says I need an interp actor and I dont know what that is.

It is just a sphere and I want it to orbit around another sphere and probably have it trail some particles as well.

v=THCR9p5mIz0

This helped me a ton, and will show you how to move the object like you want, as far as particles go I’m not sure on that one.
