What kids don't always know.

From A Private Universe:

www.learner.org/resources/series28.html#


We know seasons are about the tilt and its influence of the angle of the rays

http://www.astronomy.ohio-state.edu/~pogge/Ast161/Unit2/seasons.html


They think there is a large ellipse that causes the seasons

http://www.astronomy.ohio-state.edu/~pogge/Ast161/Unit2/seasons.html


What we know is that isn't THAT elliptical

difference is only 5 million kilometer currently

Current difference of approximately

5 million kilometers

This does influence solar radiation by about 6%*
