Not very convincing... most asteroids are darker, and their crater rims 
aren't as pronounced as on your picture, instead, they are more or less 
subdued by erosion because of billions and billions of micro-impacts. 
And at least the large crater facing the camera is elongated - which 
almost never happens in reality!

Here is what I put together after Mark's last posting (still WIP)... 
note the scale bars included!

My asteroid is far from being finished, as I noted two strange effects: 
firstly, even though I provided also a few larger craters in my 
13-partite combined crater function, after averaging it with small-scale 
noise (for simulating micro-impact erosion), these larger ones 
disappeared completely, and secondly, when I use a crater function 
consisting of more then 13 individual crater "layers" (i. e. single 
crackle <x, 0, 0> functions), no craters are rendered at all!

In the future, I also plan to add several 10,000 random boulders to be 
placed on the surface of the asteroid, a view from "pedestrian 
perspective", perhaps even a surface sampling probe just landed (like 
Japanese-made Hayabusa)...

See you in Khyberspace!
