There are some amazing scientific experiments that happen everyday that you never hear about, I'm not sure if this is one of them but it's an interesting idea.
Scientists are thinking about capturing an asteroid out of space and dragging it into the orbit of the moon, giving the moon a moon. Don't worry though, the asteroid is only going to be about 20 feet in size. The guys from NASA say this:
A captive asteroid would be a lot easier to pick apart and study, not to mention land on. It wouldn't be astronomically expensive, either: at $2.6 billion, the plan's cost lands in the same ballpark as the Curiosity rover. All this could happen sometime in the 2020s, according to the plan.
This could be the beginning of some interesting space experiments...
