Harpalyke
Harpalyke is one of Jupiter's irregular moons. It was discovered on September 9, 2000, by a team of astronomers led by Brett J. Gladman. Harpalyke is part of the Ananke Group, a collection of irregular moons with similar orbital characteristics. Harpalyke's small size and distant orbit around Jupiter limit the available information about its physical characteristics, composition, and surface features. It follows a retrograde, highly inclined orbit around Jupiter, moving in the opposite direction of the planet's rotation and at an angle to the plane of Jupiter's equator. Irregular moons like Harpalyke are believed to have originated from captured asteroids or fragments resulting from collisions.
