Earth
Earth is the third planet from the sun. Earth is the only planet known to man to consist of all the elements to support life. Earth is the perfect distance away from the sun, has a nearly circular rotation so liquid water can exist and the atmosphere consists of the perfect balance for living creatures to thrive. It also has a mild greenhouse effect so it is not to warm nor cold.
What is precession?- Precession is the wobble in Earth's axis. Earth is tilted at an angle. This tilt causes our seasons. It takes around 26,000 years for one cycle of precession to finish. The sideways pull on Earth comes from the Moon's gravitational pull.
