Close to the Sun, but still cold? January 3, 2011

Posted by Marie in 365 Days of Astronomy, Meteorwatch, Sun.

I have discovered that at 7pm today (January 3rd), the Earth will be the nearest to the sun that it gets all year.

So why is it so cold??!!

I won’t even begin to explain in any detail, because I’m not capable, but thanks to the links below, I can understand that it is because up here in the frozen north, we are tilted away from the sun and being as close as we are going to be for the year doesn’t warm us up any 😦

This first link helped me understand a little, and suggests an experiment with a left-over Christmas satsuma to provide a visual aid to explain.

This one has a good image which helped me, too.
