Here what forest said Earth is the third planet from the sun and the only object in the known universe for the harbor of life. According to radiometric dating and other sources of evidence, the earth formed over 4 billion years ago. [24] [25] [26] Earth's gravity interacts with other objects in space, especially the sun and the moon, only a natural satellite of the earth. The earth revolves around the sun in 365.26 days, a period known as the year of the earth. At this time, the Earth rotates about its axis about 366.26 times. [No. 5] The axis of the Earth's rotation is tilted, producing seasonal variations on the surface of the planet. [27] The gravitational interaction between the Earth and the Moon causes ocean tides, stabilizes the orientation of the earth around its axis and gradually slows its rotation. [28] The earth is a dense planet in the solar system and the largest of the four earth-like planets.
