Solstice Animations

  • Released Tuesday, June 20, 2023

Earth orbits at an angle, so half the year, the Northern Hemisphere is tilted toward the Sun — this is summer in the Northern Hemisphere, and winter in the Southern Hemisphere. The other half of the year, the Northern Hemisphere is tilted away from the Sun, creating winter in the north and summer in the south.

Solstices happen twice per year, at the points in Earth’s orbit where this tilt is most pronounced. These days are the longest (in the summer hemisphere) and shortest (in the winter hemisphere) of the year, and mark the change of seasons to summer and winter, respectively.
