Here's how it works:
* The Sun's Mass: The Sun is incredibly massive, meaning it has a lot of matter packed into a small space. This mass creates a strong gravitational pull.
* Gravitational Attraction: Gravity is a force of attraction between any two objects with mass. The more massive an object, the stronger its gravitational pull.
* Orbiting Path: Planets are constantly being pulled towards the Sun by its gravity. However, they also have their own momentum (a tendency to keep moving in a straight line). This combination of gravitational pull and momentum results in a curved path around the Sun, which we call an orbit.
Think of it like a ball on a string:
* The ball: The planet
* The string: Gravity
* The person holding the string: The Sun
The person swinging the ball creates a circular path, just like the Sun's gravity creates an elliptical path for the planet.
