Here's why:
* Gravity is a fundamental force: It's an attractive force that exists between any two objects with mass.
* The Sun's massive gravity: The Sun is incredibly massive, which means it exerts a strong gravitational pull on everything around it, including Venus.
* Venus's orbital motion: Venus is constantly moving, and this motion creates a balance between its inertia (tendency to move in a straight line) and the Sun's gravitational pull. This balance keeps Venus in a stable orbit around the Sun.
Think of it like a ball on a string:
* The ball represents Venus.
* The string represents the Sun's gravity.
* The force of the string (gravity) keeps the ball (Venus) from flying off in a straight line.
