Earth's Motion Around the Sun and the Seasons
Earth orbits the sun in an elliptical path, taking 365 days to complete one orbit. Earth's axial tilt causes the sunlight to hit the Earth's surface differently during the year. This changing angle of sunlight causes the four seasons: winter, spring, summer, and fall.

Did you know?
Earth's tilt is responsible for the change of seasons. The tilt creates an angle that varies from about 22.1 to 24.5 degrees over a 41,000 year cycle. Earth's orbit around the Sun is not a perfect circle, but an ellipse that causes the amount of sunlight reaching the Earth to vary slightly. Earth's orbit around the Sun is constantly changing, becoming more circular and reducing the amount of time it takes for the Earth to complete one orbit.
