The earth takes 365 and ¼ days to complete one revolution around the sun.

Revolution of the Earth around the Sun:
The Earth revolves around the Sun in a path called an orbit. This revolution is responsible for the changing seasons, the length of the day and night, and the different positions of the Sun in the sky throughout the year. Let's explore the details of how long it takes for the Earth to complete one revolution around the Sun.

Duration of Earth's Revolution:
The time taken by the Earth to complete one revolution around the Sun is known as a year. This duration is approximately 365.25 days. However, to account for this extra quarter day, we have a leap year every four years, where an additional day, known as February 29th, is added to the calendar. This helps to synchronize our calendar year with the Earth's revolution around the Sun.

Factors influencing the duration:
The Earth's revolution around the Sun is influenced by two primary factors:

1. Distance from the Sun: The Earth's orbit around the Sun is not a perfect circle but rather an elliptical shape. This means that the distance between the Earth and the Sun varies throughout the year. When the Earth is closer to the Sun, it moves faster, and when it is farther away, it moves slower.

2. Gravitational Force: The gravitational force between the Sun and the Earth also affects the duration of the revolution. The Sun's gravitational pull keeps the Earth in its orbit, and this force helps to maintain the Earth's path and speed as it revolves around the Sun.

Conclusion:
In conclusion, the Earth takes approximately 365.25 days to complete one revolution around the Sun, resulting in a year. This duration is influenced by the Earth's distance from the Sun and the gravitational force between them. It is important to understand the Earth's revolution as it plays a crucial role in the changing seasons and the variations in daylight hours throughout the year.
