what about Eccentricity (mathematics) ? there's other equation, which is wrong ?

[edit] Checking Facts After Reverting to Older Version

I just reverted the article to an earlier version because of inserted vandalism. The value of the eccentricity of Earth's orbit was also changed in the same vandalism. I assume the previous value was correct but I'm uncertain so it should be checked by someone who knows better than I. --Pigman (talk • contribs) 21:17, 26 November 2006 (UTC)

[edit] Ice Age?

Is that part about eccentricity and longer winters "favorable for triggering the next ice age" actually true? It set my bogometer off, so I thought I'd ask if anybody else has heard that theory. The only reference in the paragraph is that AOL page, which seemed a little un-scientific and POV. --W0lfie 20:26, 8 December 2006 (UTC)

pet peeve: please don't use "theory" to mean "conjecture" in a science talk page. a theory doesn't just mean some random idea in science. —Preceding unsigned comment added by 99.233.20.151 (talk) 05:05, 19 March 2008 (UTC)

[edit] Only known or only one?

I reckon that this formulation is somewhat wrong: "Planet Neptune's largest moon Triton is believed to be the only astronomical body that has a perfectly circular orbit with an eccentricity of 0." Is it not quite harsh to claim that Triton is the only body in the entire universe to have a perfectly circular orbit? Either it should be stated that it is in our Solar system or it should state that it's the only know body... or both. --Bilgrau 11:46, 23 June 2007 (UTC)
