This article could really use a diagram or animation demonstrating the eccentricity of Nereid's orbit.
Not sure what pronunciation "NER ay id" was supposed to represent. Sources (Bulfinch's, Columbia Encyclopedia, JPL/NASA) agree on [NEER-ee-id], so I changed it. --kwami 00:58, 13 Aug 2004 (UTC)
- Other sources with neer'-ee-id: Morford & Lenardon, Tripp. Gayley has ni-ree'-i-deez for the plural.
The OED has neer'-ee-id for the US & UK, and nair'-ee-id as an alternate pronunciation for the UK. I'll put that in the article. Adjectival forms in the OED: older 'Nereidean' (no pronunciation), more recent 'Nereidian' (neer'-ee-id'-ee-un, nair'-). kwami 2005 June 30 07:50 (UTC)
JPL says the mass is 2 x 10^19, but this article says it's 3.1 x 10^19 Bill Arnett (http://seds.lpl.arizona.edu/nineplanets/nineplanets/) says it is unknown I would love to know where someone got this 3.1 x 10^19 and whether it is a reliable estimate --220.127.116.11 04:44, 18 December 2006 (UTC)
- I think someone assumed(?) a density of 1.5g/cm^3. Most unexplored moons appear to assume a density of 1.3g/cm^3. With a radius of 170km you get the volume of a sphere of 20579526 km^3. Using a density of 1.3g/cm^3 yields a mass of 2.6e19 kg (1.3*20579526*10^12). Using a density of 1.5g/cm^3 yields a mass of 3.08e19 kg. -- Kheider (talk) 17:57, 22 January 2008 (UTC)
This page says the inclination to ecliptic is 5.07 degrees but NASA gives 27.6 degrees: http://solarsystem.nasa.gov/planets/profile.cfm?Object=Nep_Nereid&Display=Facts&System=Metric. Sergey feo (talk) 20:43, 29 March 2009 (UTC)
