Jarnsaxa

Jarnsaxa, designated as an irregular moon of Saturn, holds membership within the Norse group of satellites. Discovered in 2006 by astronomers using the Subaru Telescope in Hawaii, its name derives from Norse mythology—a reference to a giantess who was a notable figure as the mistress of Thor and mother to his offspring. Jarnsaxa's irregular orbit, characterized by eccentricity and inclination, sets it apart from Saturn's larger regular moons that adhere to orbits closer to the planet's equatorial plane. As part of the Norse group, alongside moons like Bergelmir and Greip, Jarnsaxa shares comparable orbital traits, suggesting a possible common origin, likely linked to the fragmentation of a larger moon. Nevertheless, due to its substantial distance from Earth and the limited availability of observational data, significant details about Jarnsaxa's physical attributes, encompassing aspects such as size, composition, and surface features, remain concealed. It is believed that Jarnsaxa, akin to other irregular moons, was captured by Saturn's gravitational pull, signifying an origin from the outer solar system.
