Earth is a little tilted, like a spinning top leaning to one side.

Northern summer Northern winter
Earth travels around the Sun once a year. Its tilt keeps pointing the same way:
- Summer: The northern half of Earth leans toward the Sun. Sunlight hits it more directly, and the days are longer.
- Winter: The northern half leans away from the Sun. Sunlight comes in at more of a slant, and the days are shorter.
The southern half has the opposite seasons: when it’s summer in the north, it’s winter in the south.
🔦 You can try this with a flashlight: shine it straight at your hand, then tilt your hand. The tilted light spreads out more, so it warms any one spot less.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
