Earth's Wonky Tilt
Why are there seasons on Earth?
Why does summer feel like the sun is hugging you, while winter makes you want to hide under three blankets? It's not because Earth scoots closer to the sun in June and runs away in December. Nope. The real reason is way cooler — and it has to do with Earth doing something a little wonky as it spins through space.
Earth takes a whole year to orbit around the sun — that's one big loop through space. But here's the thing: Earth doesn't stand up straight as it goes. It's tilted, like someone nudged it and it never bothered to straighten up. That tilt is about 23.5 degrees, which might not sound like much, but it changes everything.
