The Earth’s Orbit
ES 2: I can explain that Earth is one of
several planets to orbit (revolve and circle)
the sun, and that the moon orbits Earth.
Earth’s Orbit (Revolution)
• Elliptical- oval
• Orbit is around the sun
• Takes 365 ¼ days to
complete its orbit
• Earth is traveling at 67,000
mph while it orbits
• Tilt of the axis makes
seasons
