What is Thrymr (moon)?
'''Thrymr''' or '''Saturn&nbsp;XXX''', is a [[Satellite (natural)|moon]] of [[Saturn (planet)|Saturn]]. It was found by [[Brett J. Gladman|Gladman]], et al. in 2000, and given the designation '''S/2000&nbsp;S&nbsp;7'''. Thrymr is about 5.6 kilometres in diameter, and orbits Saturn at an average distance of 20,810,000&nbsp;km in 1120.809 days, at an [[inclination]] of 175° to the [[ecliptic]] (151° to Saturn's equator), with an [[Orbital eccentricity|eccentricity]] of 0.453. Thrymr may have formed from [[debris]] knocked off of [[Phoebe (moon)|Phoebe]] at some point in the past. Its name comes from [[Norse mythology]], where [[Thrymr]] is a [[Jotun]] or frost giant. The name was said as '''Thrym''' in [http://cfa-www.harvard.edu/iauc/08100/08177.html IAU Circular 8177]. However, the [[International Astronomical Union|IAU]] [[Working Group on Planetary System Nomenclature]] later decided to add the [[nominative case]] ending ''-r'' to the root ''Thrym''. == References == * [http://cfa-www.harvard.edu/iauc/07500/07538.html IAUC 7538: ''S/2000 S 7, S/2000 S 8, S/2000 S 9''] 2000 December 7 (discovery) * [http://cfa-www.harvard.edu/mpec/K00/K00Y15.html MPEC 2000-Y15: ''S/2000 S 1, S/2000 S 2, S/2000 S 7, S/2000 S 8, S/2000 S 9''] 2000 December 19 (discovery and ephemeris) * [http://cfa-www.harvard.edu/iauc/08100/08177.html IAUC 8177: ''Satellites of Jupiter, Saturn, Uranus''] 2003 August 8 (naming the moon ''Thrym'') * [http://cfa-www.harvard.edu/iauc/08400/08471.html IAUC 8471: ''Satellites of Saturn''] 2005 January 21 (correcting the name) {{Moons of Saturn}} {{sci-stub}} [[Category:Saturn's moons]]
