Does the World Revolve Around the Sun?

A Scientific Explanation of the Earth's Orbit

The Earth's Orbit

The Earth revolves around the Sun in an elliptical orbit, meaning that its distance from the Sun varies throughout the year. At its closest point to the Sun, called perihelion, the Earth is about 147 million kilometers away. At its farthest point from the Sun, called aphelion, the Earth is about 152 million kilometers away.

The Earth's orbit takes 365.25 days to complete, which is why we have a leap year every four years to account for the extra quarter day.

The Sun's Gravity

The Sun's gravity is what keeps the Earth in orbit. The Sun's gravity pulls on the Earth, and the Earth's gravity pulls back on the Sun. These two forces are equal, which is why the Earth stays in orbit around the Sun.

The Sun's gravity is also what causes the Earth's seasons. As the Earth orbits the Sun, different parts of the Earth are tilted towards or away from the Sun. This causes the amount of sunlight that reaches different parts of the Earth to vary, which in turn causes the seasons.

The Earth's Axis

The Earth's axis is tilted at an angle of 23.5 degrees. This tilt is what causes the Earth's seasons. As the Earth orbits the Sun, different parts of the Earth are tilted towards or away from the Sun. This causes the amount of sunlight that reaches different parts of the Earth to vary, which in turn causes the seasons.

The Earth's axis also causes the Earth's day and night cycle. As the Earth rotates on its axis, different parts of the Earth are facing towards or away from the Sun. This causes the parts of the Earth that are facing the Sun to experience daylight, while the parts of the Earth that are facing away from the Sun to experience night.

Conclusion

The Earth revolves around the Sun in an elliptical orbit. The Sun's gravity is what keeps the Earth in orbit. The Earth's axis is tilted at an angle of 23.5 degrees, which causes the Earth's seasons. The Earth's axis also causes the Earth's day and night cycle.
