Earth’s revolution around the sun
Earth's revolution around the sun, also known as its orbit, is the movement of the Earth around the sun in a slightly elliptical path. This revolution takes approximately 365.25 days to complete, which is why we have leap years every four years to account for the extra quarter day.
The Earth's orbit is not a perfect circle but rather an ellipse, with the sun located at one of the two foci. This means that at certain times during the year, Earth will be closer to the sun (perihelion) and at other times, it will be farther away (aphelion).
The tilt of the Earth's axis is another important factor in its revolution around the sun. This tilt is approximately 23.5 degrees, and it causes the changing of seasons as different parts of the Earth are exposed to varying amounts of sunlight throughout the year.
Earth's revolution around the sun is responsible for the cycle of seasons, as well as the length of a year. It also affects the distribution of sunlight and the Earth's climate.
