Bergelmir

Bergelmir, an irregular moon of Saturn, belongs to the Norse group of satellites. Discovered in 2004 by astronomers using the Subaru Telescope in Hawaii, its name originates from Norse mythology—a reference to a giant who was a descendant of the primordial giant Ymir. Bergelmir's irregular orbit, marked by eccentricity and inclination, distinguishes it from Saturn's larger regular moons. As part of the Norse group, alongside moons like Gridr and Hyrrokkin, Bergelmir shares similar orbital characteristics, hinting at a possible common origin, potentially stemming from the fragmentation of a larger moon. Essential details about Bergelmir's physical attributes, including size, composition, and surface features, remain concealed due to its significant distance from Earth. It is believed that Bergelmir, like other irregular moons, was captured by Saturn's gravitational force, likely originating from the outer solar system.
