The average distance between Earth and the Sun is approximately 149.6 million kilometers, also known as one astronomical unit (AU).

Earth takes approximately 365.24 days, or one year, to complete one orbit around the Sun.

Earth's rotation refers to the movement of Earth on its axis, which causes day and night.

Earth completes one rotation on its axis in approximately 24 hours, which is equivalent to one day.

Earth's revolution refers to the movement of Earth around the Sun, which causes the seasons.

Earth completes one revolution around the Sun in approximately 365.24 days, which is equivalent to one year.

Earth's axis is tilted at an angle of approximately 23.5 degrees, which causes the seasons.

Earth's precession refers to the movement of Earth's axis around the Sun, which causes the gradual shift in the position of the equinoxes and solstices.

Earth's precession takes approximately 26,000 years to complete one cycle.

Earth's nutation refers to the small, irregular variations in the orientation of Earth's axis.

Earth's nutation takes approximately 18.6 years to complete one cycle.

Earth's obliquity refers to the tilt of Earth's axis, which causes the seasons.

Earth's obliquity is approximately 23.5 degrees.

Earth's eccentricity refers to the variation in Earth's orbit around the Sun, which causes the difference in the length of seasons.

Earth's eccentricity is approximately 0.0167.
