I'm stunned that there is a dusty surface that looks like sand. How much gravity does the comet have?

- joezydeco 12y ago"The acceleration due to gravity on the surface of Churyumov–Gerasimenko has been estimated for simulation purposes at 10^(−3) m/s^2, or about one ten-thousandth of that on Earth." http://en.wikipedia.org/wiki/67P/Churyumov%E2%80%93Gerasimenko http://en.wikipedia.org/wiki/67P/Churyumov%E2%80%93Gerasimen...
- b_emery 12y agoSo it seems safe to say that a 'landslide' will not occur (as suggested by one of the captions). Instead, a boulder might break off and float away? The whole thing must be held together by the chemical bonds inherent to the material.
- joezydeco 12y agoHard to say. The whole point of sending a robot to the comet is to see what it's made of and how the surface is set up. It could be all loose snow, it could be rock, could be something else.
