Earth Around the Sun
Age 10 · Astronomy
Earth travels around the Sun once every year. Its axis always leans the same way, so the length of daylight and the height of the Sun in the sky change through the year.

- Globe at the left of the lamp: its northern half leans toward the bright lamp.
- Tilted rod through the globe: the axis stays parallel to the other rods.
- Bright half of the globe: the side facing the lamp is in daylight.
- Dark half of the globe: the side facing away from the lamp is in night.
Examples
- Summer at the beach has longer days and a higher Sun than winter.
- A shadow at noon is shorter in summer than in winter.
Key takeaways
- Earth’s tilt stays pointed the same way as it orbits the Sun.
- Changing daylight hours and Sun height cause the seasons.
