Here's how it works:
* The Sun's Gravity: The Sun is incredibly massive, and its immense gravity acts like a giant invisible tether, pulling all the planets towards it.
* Orbital Velocity: The planets are also moving at a high speed, constantly orbiting the Sun. This forward motion acts against the Sun's pull, preventing the planets from falling directly into the Sun.
* Balance: The planets' orbital speed and the Sun's gravity are perfectly balanced. Think of it like a ball on a string being swung around. The tension in the string (gravity) keeps the ball from flying off, while the ball's speed (orbital velocity) keeps it from falling inwards.
This delicate balance is what keeps the planets in their orbits around the Sun, preventing them from flying off into the vastness of space.
