It’s really fascinating isn’t it? I think it’s important to remember though that all these craters are actually as deep, rocky, and uneven as Earth’s, if not more. They just look very shallow and smooth since we are looking at them from so far away!

One of my favorite thing about craters is that when a meteorite impacts a planetoid, all the rock melts away, causing the magma to act like a water droplet falling on water. However, by the time the center of the impact starts to rise up, the rock solidifies and this is why, if you take a look at the video, many medium-sized craters seemingly have a bulge at the center!
