At the same time, the southern half of Earth is tilted away from the sun and catches its rays at an angle, causing the cooler, shorter days of winter.Įarth is bathed evenly in sunlight only twice a year, on the equinoxes. When the planet's Northern Hemisphere is tilted toward the sun, sunlight hits it head on, bringing summer’s heat and longer days. So if it’s not Earth’s changing proximity to the sun, what gives us seasons? It's all in the slant: Earth's axis isn’t straight up and down relative to the sun, but tilted at a slight angle of about 23.5 degrees.Īs Earth revolves around the sun, it maintains that tilt, and the sun’s light doesn't hit the entire surface directly. “So in the northern winter-in December-the sun is actually closest to the Earth by a small amount, and in the summer it’s actually farther away.” “The Earth’s orbit is about 3 percent out of round,” explains Jay Holberg, a senior research scientist at the lunar and planetary lab at the University of Arizona. The Harvard grads-captured forever in 1980s hair and their caps and gowns-were wrong. After all, Earth’s orbit isn’t a perfect circle.
