[QUOTE="Shemjaza, post: 75447108, member: 146291"] The difference between rocks on an asteroid and rocks on a cliff or the side of a plane is that there are other forces in operation in those instances. On the cliff there is the gravity of the Earth pulling downwards and on the plane there is both that gravity and the friction of the air acting against you. On an asteroid the minuscule gravity of the objects will be the biggest force around. As to how a lander can "land" on an asteroid, yes, bouncing off is a real concern. A term that conjures a clearer mental image would have been "docking", the lander would have to match velocities with the asteroid and gently touch down. [/QUOTE]
