Bergelmir is about 6 kilometers (4 miles) in diameter,[3] and orbits Saturn at an average distance of 19,338,000 km in 1006.659 days, at an inclination of 157° to the ecliptic (134° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.152. Its rotation period is 8.13±0.09 hours.[2]
It was named in April 2007 after Bergelmir, a giant from Norse mythology and the grandson of Ymir, the primordial giant. Bergelmir and his wife alone among their kind were the only survivors of the enormous deluge of blood from Ymir's wounds when he was killed by Odin and his brothers at the dawn of time. Bergelmir then became the progenitor of a new race of giants.
^The 'g' has a 'y' sound in Norse (indeed gelmir sounds like what it means in English, 'yeller'), but a spelling pronunciation would have it as 'g', as 'Aurgelmir' does in Merriam-Webster's Encyclopedia of Literature (1995).
^The oblique stem of the name is Bergelmi, as in Modern Norwegian Bergelme. The -r is the nominative case ending.
