- Earth’s axis is on a tilt relative to its orbital plane. This tilt is approximately 23.5 degrees.
- As the Earth orbits the sun, its tilt always points in the same direction – towards imaginary points known as the north and south celestial poles.
- Earth’s fixed tilt has two major consequences:
- It results in day and night with different lengths on different parts of the Earth and at different times of the year.
- It results in the seasons and is also why the seasons are different in opposite hemispheres.
Earth’s axis is on a tilt which is oriented in the same direction as it orbits the sun.
