Narvi Template:IPAc-en or Saturn XXXI is a natural satellite of Saturn. It was discovered by a team of astronomers led by Scott S. Sheppard in 2003, and given the temporary designation S/2003 S 1.

Description

Narvi is about 7 kilometres in diameter, and orbits Saturn at an average distance of 19,371,000 km in 1006.541 days, at an inclination of 136.8° to the ecliptic (109° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.2990, very similar to Bestla's orbit.<ref name="Denk2018">Template:Cite book</ref> Narvi's rotation period is Template:Val hours, and its light curve has three minima like Siarnaq and Ymir. Unlike the other triangular moons, however, one minimum is much higher than the others, and the maximum that is a half-period ahead is much lower.<ref name="LPSC2654">Template:Cite conference</ref>

Naming

It was named in January 2005 after Narfi, a giant in Norse mythology. The name was approved by the IAU Working Group on Planetary System Nomenclature on 21 January 2005.
