What are the primary factors that influence the Earth's orbit and rotation?

The Earth's orbit and rotation are influenced by a variety of factors, including:

• The gravitational pull of the Sun: The Sun's gravity is the main force that keeps the Earth in its elliptical orbit. The gravitational pull of the Sun also affects the Earth's rotation by creating tidal bulges.
• The gravitational pull of the Moon: The Moon's gravitational pull causes the Earth's tides, which can affect the rotation of the Earth.
• The Earth's axial tilt: The Earth's axis is tilted at an angle of approximately 23.5 degrees, which causes the seasons as different parts of the Earth receive different amounts of sunlight throughout the year.
• The Earth's shape: The Earth is not a perfect sphere, but rather an oblate spheroid, which causes slight variations in its rotation.

In addition to these factors, there are other smaller influences on the Earth's orbit and rotation, such as the gravitational pull of other planets and asteroids, and the effects of solar wind and cosmic radiation.
