What is the gravity on Comet 67P/Churyumov-Gerasimenko?
Comet 67P/Churyumov-Gerasimenko is so small that its gravitational pull is millions of times weaker than on Earth. For this reason, the Rosetta lander will touch down at no more than walking pace. It will need its ‘harpoon’ system to safely anchor it to the comet’s surface and prevent it from bouncing back into space.
