That’s No Space Station. It’s a Moon.

Tethys with craterOdysseus is the name of the huge crater on Saturn’s moon Tethys. Tethys is a bit more than 1000 km in diameter, and the crater is roughy 450 km across. To put that into scale, a crater that covered the same percentage of the Earth’s surface would be about the size of Africa.
