Discovery

Narvi was discovered on April 8, 2003 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna, from photos taken from Feb. 5 to 3 April 3.

Overview

Narvi has a mean radius of 2.2 miles (3.5 kilometers), assuming an albedo (a measure of how reflective the surface is) of 0.04. It orbits Saturn at an inclination of about 143 degrees and an eccentricity of about 0.4. At a mean distance of 12.1 million miles (19.4 million kilometers) from Saturn, the moon takes about 1,004 Earth days to complete one orbit.

Narvi is a member of the Norse group of moons. These "irregular" moons have retrograde orbits around Saturn -- traveling around in the opposite direction from the planet's rotation. Narvi and the other Norse moons also have eccentric orbits, meaning they are more elongated than circular.

Like Saturn's other irregular moons, Narvi is thought to be an object that was captured by Saturn's gravity, rather than having accreted from the dusty disk that surrounded the newly formed planet as the regular moons are thought to have done. Narvi appears to be a member of a subgroup with Bestla.

How Narvi Got its Name

Originally called S/2003 S1, Narvi was named for a son of Loki in Norse mythology.
