Part of the show Naked Science Questions and Answers
Chris in Yorkshire asked:
I have question about meteors. If someone was to land on one, would they have to hold on like if they were on the edge of a car moving down the road or would you even notice you were moving like we don't notice on Earth?
You would have to hold on but not because it's moving but because the gravity is so low on an asteroid. In fact we've launched the Rosetta mission that's going to land on CG, which is its short name, and that's going to have harpoons on it to lock itself onto the asteroid. If it didn't then it would just float away.
