3 days ago10 solstice facts for everyone to know
This December, like every December, will include a single moment - often marked by a particular day, which is December 21st here in 2025 - where our planet's axial tilt is perfectly aligned with the invisible line connecting the Earth to the Sun. In December, it's the northern hemisphere's pole that's tilted away from the Sun, while the southern hemisphere's pole is tipped towards it; in June, the opposite situation is true.
