Praxidike, also known as Jupiter XXVII, is a retrograde irregular shaped satellite belonging to the outer planet of Jupiter. This satellite was discovered by Scott S. Sheppard, David C. Jewett, Yanga R. Fernandez, Eugene A. Magnier on November 23, 2000 at the Mauna Kea Observatory. This satellite belongs to the Ananke group, a group of irregular shaped retrograde satellites.

FormationEdit

Praxidike formed when a D-type asteroid, from possibly the Jupiter Trojans or the Hilda family, and was pulled into Jupiter's gravitational pull after being launched into deep space. The D-type asteroid, later named Ananke, suffered several collisions. The leftover debris from the asteroid became the other satellites of the Ananke group, with Ananke being the largest of the group.

SurfaceEdit

Praxidike, common in the Ananke group, has a brownish grey surface. Praxidike has no visible mountainous areas yet for the ones seen by the infrared spectrum given off by Praxidike. Craters are clearly visible on the surface, yet these geographical features are not common in the Ananke grouped moons. They could have possibly been from the formation of the Ananke grouped satellites.
