Summer's hotter because you're closer to the sun.
Ah, summer! That magical time of the year when your hemisphere reaches as close to the sun as it can go, yearning for a burning hug that's only slightly cooled by aloe vera. After a day at the beach with nothing more than one application of SPF 15, you might be cursing our planet for tipping you so close.
Because hey, we all know that's what summer is -- we're leaning closer to the sun! In the winter we're leaning away from the sun. Voilá! SCIENCE.
Totally inaccurate and misunderstood science.
We are right in one respect: The sun is super hot. Yet at 93 million miles (150 million kilometers) away, it's not so hot that a little lean this way or that matters to us beach or ski bums. It's not the proximity of your hemisphere to the sun that makes summer warm and winter cold; it's the angle that the sun's rays hit us. In the summer, the sun's rays hit right on us. In the winter, the sun's rays are slanted down, away from us [source: GEMS].
