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)

Data that needs added, and verified[edit]

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.

Suggested merge with Arctic Circle[edit]
