I have an idea for a new block called Orbit. It is a bit complicated, though. Here is a link to a slideshow explaining the whole block:
View in Present mode for reading the small text.
A quick note: I am still thinking about what the orbit editor would look like inside the block. Maybe it could show your game level, with a highlight around the orbiter and orbitee? It could have a tool to increase and decrease the radius, a pen tool, and let you pick from the orbit presets. Any suggestions or ideas on this block?
