Here's how it works:
* The Sun's Mass: The Sun has an immense amount of mass, which creates a powerful gravitational field that extends far out into space.
* Attraction: This gravitational field attracts all objects, including planets, towards the Sun.
* Orbital Motion: Planets don't fall directly into the Sun because they are also moving forward, at a velocity that is just right to balance the Sun's gravitational pull. This creates a curved path called an orbit.
* Balance: Imagine a ball on a string being swung around in a circle. The string represents the Sun's gravity, and the ball's motion represents the planet's orbital velocity. If the string is too short or the ball is moving too slowly, it will fall inwards. If the string is too long or the ball is moving too quickly, it will fly away.
Essentially, the planets are constantly falling towards the Sun, but their forward motion keeps them from actually hitting it. This balance of gravity and motion keeps them in their orbits around the Sun.
