hi , how earlier scientist figure out that Earth has elliptical motion rather than circular around sun?
The Earth revolves in an elliptical path because of the gravitational pull from the sun. As the Earth moves around the sun, the force of gravity causes it to follow an elliptical path rather than a perfect circle.
The Earth takes approximately 365.24 days to complete one revolution around the sun in its elliptical path. This is why we have leap years every four years to account for the extra 0.24 days.
Yes, the Earth's distance from the sun does change during its elliptical orbit. At its closest point, called perihelion, the Earth is about 91 million miles from the sun. At its furthest point, called aphelion, the Earth is about 94.5 million miles from the sun.
The shape of the Earth's elliptical path is an elongated circle called an ellipse. This shape is created by the gravitational pull of the sun and the Earth's own motion.
The Earth's elliptical path does not directly affect our seasons. The tilt of the Earth's axis is actually what causes our seasons. However, the changing distance between the Earth and the sun does have a small impact on the intensity of the seasons. When the Earth is closer to the sun, the seasons may be slightly warmer, and when it is further away, the seasons may be slightly cooler.
