Herschel (/ˈhɜːrʃəl/) is the largest impact crater on the Saturnian moon Mimas.

[3] It is so large that astronomers have expressed surprise that Mimas was not shattered by the impact that caused it.

Large chasms (termed chasmata) that may be stress fractures due to shock waves from the impact traveling through it and focusing there can be seen on the opposite side of Mimas.

The impact is also suspected of having something to do with the current "Pac-Man"–shaped temperature pattern on Mimas.

[6][7] This is a coincidence, however, as the crater's similarities were not discovered until 1980 after Voyager 1 gained line of sight, three years after the film was made.
