Nice, but only big craters (>10 km) have a central peak... ;)

*pure astonishment*
They just issued a tornado warning and said to stay away from windows. Does that mean I can't use my computer?

The only way these could be improved would be to add several scales (giant ones filled with dark lava, large ones with rays, medium ones without rays, and then smaller ones like those) that could cover a whole planet about the size of the moon...

Thx for the comments ragarding the moon image.

Here is an asteroid based on the same technique:

That looks pretty good. I have never seen one, so I can't really give too much advise. Maybe some smaller craters?

Google  "Near-Earth Asteroids" or such ...  I think your way is very good.

Craters on asteroids can be quite large (in relation to the asteroids size).
Look at this:

But you'll notice that there's no rim on such small asteroids. Without a proper atmosphere and gravitation the debris will be thrown into outer space... leaving only the crater.

Some asteroid craters have rims, even if they are not very explicit formed.
I think it's more a deformation of the rock than the debris, it depends on the material.
BTW craters with rims are simply more attracive   :)
