Tilted

Bonus Fun Fact: Next Monday, December 21st, will be the longest night of the year — the Winter Solstice. This may sound like some kind of dark prophecy, but it’s really just an astronomical fact. As the Earth hurtles through space, orbiting the sun, it does so in a tilted fashion. Specifically, 23.5 degrees of tilt. Incidentally, it’s this tilt that creates the seasons. The Winter Solstice is the point in orbit where the Earth’s axis is maximally tilted away from the Sun. It may be the longest night but, on the bright side (ha!), the nights will get shorter from here into summer.

As the Earth orbits the Sun, it’s axis tilts towards or away from the Sun. The point of maximum tilt is a Solstice, either away from the Sun (Winter Solstice) or towards (Summer Solstice). Figure credit MIT/Alissa Earle via NASA’s Pluto New Horizons Blog.
