Hermippe, also known as Jupiter XXX, is a retrograde irregular-shaped satellite belonging to the outer planet of Jupiter. This satellite was discovered by Scott S. Sheppard, David C. Jewett, and Jan T. Kleyna at the Mauna Kea Observatory on December 9, 2001. This satellite is part of the Ananke group, a group of retrograde irregular satellites with Ananke being the largest of the group.

FormationEdit

Hermippe was formed by the fragments of the Ananke group. After Ananke was pulled into Jupiter's gravitational pull, it suffered numerous collisions and the debris became the moons of the Ananke group. Hermippe was one of those moons.

DescriptionEdit

SurfaceEdit

Hermippe has a grey surface, odd due to it being an Ananke grouped moon. The grey surface must come from the ions located in the outer regions of Jupiter, or it is possible that Hermippe was the asteroid that in fact caused the formation of Ananke group, and it was, in fact, a D-type asteroid with a dark grey surface.

Non-Spherical ShapeEdit

None of the Ananke moons are massive enough to maintain hydrostatic equilibrium, with Hermippe just being another example of this trait.

NamingEdit

Hermippe was once given a provisional name. It is named after the mother of Orchomenos. She was one of the many lovers of the Greek god Zeus, or the Roman god Jupiter.
