How do we know how the earth revolves around the sun?

The Earth revolves around the Sun due to the force of gravity. This movement was first explained by Johannes Kepler in the 17th century and later confirmed by observations and calculations made by scientists like Galileo and Newton. Today, we know the Earth's orbit around the Sun is an elliptical path, with the Sun at one of the foci. This understanding is based on centuries of scientific research and observation.
