Explain why the planets in our solar system revolve around the Sun in their orbits.

Explanation

To explain why the planets in our solar system revolve around the Sun in their orbits, we can break down the explanation into several key steps:

### Step 1: Understanding Mass
The first thing to note is the mass of the Sun compared to the planets. The Sun contains about 99% of the total mass of the solar system. This significant mass means that the Sun has a strong gravitational pull.

### Step 2: Gravitational Force
The gravitational force is the force of attraction that exists between two masses. In our case, the Sun (with mass \(M_S\)) and each planet (like Earth with mass \(M_E\)) exert a gravitational force on each other. This force is what keeps the planets in orbit around the Sun.
