A polar projection would be nice. OverMyHead 07:55, 28 February 2007 (UTC)

I suggest "northern solstice" and "southern solstice" or "solstice of Cancer" and "solstice of Capricorn". The only great circle mentioned is the equator; the rest are small circles. -phma

Why are you suggesting these terms when they're not the terms that the circles are known as? -- Zoe
It seems to me that "The other great circles are:" is the part that needs to be changed here, not the circles that are referenced. --Brion VIBBER

will major circles suffice? Lir 17:38 Nov 4, 2002 (UTC)

Lir, see great circle. --Ed Poor
On second thought, the circle of latitude really could be re-written for clarity. If I didn't already know what they were, I would hardly have understood any of them. --Ed Poor

What's wrong with circle of latitude? COuld you explain on that talk page, Ed? -- Tarquin 19:43 Nov 4, 2002 (UTC)

[edit] Data that needs added, and verified

There's an apparent error in the Arctic_circle article. This ambiguity needs corrected (whichever article is in error) and the relevant data duplicated to Antarctic_circle.

This line "The main long-term cycle has a period of 41000 years and an amplitude of about 0.68°, or 76 km on the surface." does not jibe with this info "The Earth's axial tilt varies between 21.5° and 24.5° with a 41,000 year periodicity" from Axial_tilt.

That's a 3 degree difference, not .68 degree. If the 3 degree figure is correct, this article needs corrected. It would be nice to add the distance range for the Arctic and Antarctic circles to the Axial tilt article.

[edit] Suggested merge with Arctic Circle
