Final answer:
Saturn's satellite Mimas looks like the Death Star from Star Wars, mainly due to the large Herschel crater, which gives it a similar appearance.
Step-by-step explanation:
One of Saturn's satellites bears a striking resemblance to the Death Star from the Star Wars movies, and this satellite is known as Mimas. Mimas has a distinctive feature that contributes to its Death Star-like appearance: a large impact crater named Herschel, which measures about 130 kilometers across. The scale of the crater compared to the size of Mimas is such that it gives the moon an appearance similar to the iconic space station from the Star Wars saga, including the concave shape and central peak reminiscent of the Death Star's superlaser.
