initial velocity for simulating planetary motion I was going to simulate planetary motion in blender and i have simulated the gravitational attraction between two planets with rigid body and force field.
but i don't have any idea about how to give one of them initial velocity with physical accuracy
If there is a way to do this with python that would be awesome!!
Here is my blender file :

There is a problem with the common trick of giving objects initial velocity because it suddenly disappears :
an initial velocity in a rigid body simulation is very easy to do:

check animated checkbox and keyframe a location

keyframe another location on another later frame (distance + keyframe distance will &quot;make&quot; the speed

one keyframe later: disable animated checkbox and keyframe it
