With this Blueprint, you can create different Orbits, including Moons.
The Speed of each Actor in a orbit is calculated by the Mass Parameter of its Parent Object. This also applies to elliptical Orbits, where the Object changes it speed, depending on the distance to the Parent.
Orbits are created as Splines.
