Mimas: The Real-Life Death Star

The video explores Mimas, Saturn's smallest major moon, known for its resemblance to the Death Star. Discovered by William Herschel in 1789, Mimas features the Herschel Crater, which was formed by a massive impact. The crater's central peak is similar in size to Mount Everest. Mimas is composed mostly of water ice, possibly receiving fresh ice from Enceladus. Despite its small size, Mimas is larger than the first Death Star. Its gravitational pull affects Saturn's rings, creating the Cassini Division. The video concludes with a nod to the scientific intrigue surrounding Mimas.
