The point is this
http://www.windows.ucar.edu/tour/link=/ ... stics.html
at its closest distance to the sun, in January (northern winter) the earth is 91 million miles from the sun,at its farthest from the sun (northern summer) the earth is 94.5 million miles from the sun. During the hotter northern hemisphere months, the earth is 3.5 million miles farther from the sun than during the colder ones.

I remember seeing the answer to that question. The position adds an additional 2*C to the average temperature swing.frozen wrote:Does the sun being closest in the summer & farthest in the winter in the southern hemisphere, result in warmer summers & colder winters overall than in northern hemisphere?

9 July 2007; small grammatical error & sunspot?
Thanks for a great picture to show my non-scientist friends when trying to explain that it's the tilt of the earth (and not the eccentricity of our orbit) that gives us our seasons! By the way, what is the black dot in the second image?
The text contains a grammatical error. "If the Earth's orbit was perfectly circular," should read "If the Earth's orbit WERE perfectly circular," as the verb is in the subjunctive case.

I love APOD; what a fantastic site! [/i]

The black spot in the second image is a sunspot that was visible when the image was taken in July 2006.

In 12000 years from now, as the Earth precesses, It will be absolutely false down under.gadieid wrote:It is not a misconception. It is absloutly true provided that you are in the southern hemisphere![u]APOD[/u] wrote:A common misconception is that the Sun is most distant during the winter,

thanks for info, now I get where "if I were you" comes from.cricket wrote:The text contains a grammatical error. "If the Earth's orbit was perfectly circular," should read "If the Earth's orbit WERE perfectly circular," as the verb is in the subjunctive case.
