Herschel (/ ˈ h ɜːr ʃ əl /) is the largest impact crater on the Saturnian moon Mimas. It is located on Mimas's leading hemisphere, centered on the equator at 112° longitude . It is named after the 18th-century astronomer William Herschel , who discovered Mimas in 1789.
Mimas's most distinctive feature is a giant impact crater 139 km (86 mi) across, named Herschel after the discoverer of Mimas. Herschel's diameter is almost a third of Mimas's own diameter; its walls are approximately 5 km (3 mi) high, parts of its floor measure 10 km (6 mi) deep, and its central peak rises 6 km (4 mi) above the crater floor.
This is a list of named geological features on Mimas, a moon that orbits the planet Saturn. Mimantean features are named after people and places in Arthurian legend or the legends of the Titans . The sole exception to this is Herschel Crater , named after William Herschel , the astronomer who discovered Mimas in 1789.
There are several impact craters named Herschel in the Solar System, although the best known is the huge crater on Saturn's moon Mimas. Most are named after the eighteenth-century astronomer William Herschel. Herschel (lunar crater), on the Moon; Herschel (Martian crater), on Mars; Herschel (Mimantean crater), on Mimas
The most prominent of these is the crater Stickney, a large impact crater some 9 km (5.6 mi) in diameter, which takes up a substantial proportion of the moon's surface area. As with Mimas ' crater Herschel , the impact that created Stickney must have nearly shattered Phobos.

Juno (minor-planet designation: 3 Juno) is a large asteroid in the asteroid belt.Juno was the third asteroid discovered, in 1804, by German astronomer Karl Harding. [15] It is tied with three other asteroids as the thirteenth largest asteroid, and it is one of the two largest stony asteroids, along with 15 Eunomia.
