Capture a large asteroid and tow it into orbit around the Moon, so we can see a moon orbiting a moon, orbiting a planet, orbiting a sun, orbiting a galactic core. We can name it Matryoshka.

Methinks you have created a Three Body Problem

Wait until you hear about the Lunar Reconnaissance Orbiter. The moon already has something orbiting it!

A natural satellite orbiting a larger natural satellite is called a [moonmoon](https://en.wikipedia.org/wiki/Subsatellite)

That's awesome

We should also put a small asteroid in orbit around the large asteroid and then put a satellite in orbit around the small asteroid.

I don't think physics would let it happen, but I like the spirit!
