I have a bit of a strange request. I am trying to create a scene to simulate double and multiple star systems - and i’m trying to find an easy way to position the stars in the scene.

The data for these stars is given relative to the primary star. That is - you have a parent star assumed to be at the origin - and any secondary, tertiary stars are given a distance and angle from the parent.

What I therefore need is to rig a sphere at the origin. Then I need 2 or 3 more spheres that I can position based on distance and angle from the origin (the spheres will represent the stars)

I’m imagining it almost like a clock face - with the primary at the centre and the other stars at the ends of the hour and minute hands…but I need to be able to vary the angle and length of the hands precisely (i.e. using numeric input) without scaling the spheres.

Can anyone help. Thanks
