According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. It is only planate where people live. It is the third planet from the Sun and the only astronomical object known to harbour life. Its gravity interacts with other objects in space. The Sun and the Moon are the, its satellite. It revolves around the Sun in 365.26 days. This period of time is known as an Earth year.
Earth’s axis of rotation is tilted. This nature of earth produces seasons on Earth. The gravitational interaction between Earth and the Moon causes ocean tides, stabilizes Earth’s orientation on its axis, and gradually slows its rotation. This planate is the densest planet of the Solar System.
