If the Hayden Sphere is the size of Saturn’s moon Janus, then this model is the relative size of Meteor Crater.

Meteor Crater is the scar from the impact of an iron meteorite that struck Arizona about 50,000 years ago. It is as wide as a dozen football fields and as deep as a 50-story building. The largest surviving impact craters on Earth are similar in diameter to Saturn’s moon Janus.
