Order of planets according to distance from the Sun is :

Question

Accepted Answer

The order of planets according to their distance from the Sun is crucial for understanding our solar system's structure. Let's examine why Option 3, "Mercury, Venus, Earth, Mars," is the correct order and why the other options are incorrect.

1. **Explanation for Option 3: Mercury, Venus, Earth, Mars**
   - **Mercury** is the closest planet to the Sun. It orbits the Sun at an average distance of about 57.9 million kilometers (36 million miles).
   - **Venus** is the second planet from the Sun, orbiting at an average distance of about 108.2 million kilometers (67.2 million miles).
   - **Earth** is the third planet from the Sun, with an average distance of about 149.6 million kilometers (93 million miles).
   - **Mars** is the fourth planet, orbiting at an average distance of about 227.9 million kilometers (141.6 million miles).

This sequence is based on the increasing distance from the Sun, making Option 3 the correct order.

2. **Explanation for why other options are incorrect:**

- **Option 1: Mercury, Venus, Mars, Earth**
     - This option incorrectly places Mars before Earth. Mars is actually farther from the Sun than Earth, making this order incorrect.

- **Option 2: Venus, Mercury, Earth, Mars**
     - This option incorrectly places Venus before Mercury. Mercury is closer to the Sun than Venus, so this order is incorrect.

- **Option 4: Mercury, Earth, Venus, Mars**
     - This option incorrectly places Earth before Venus. Venus is closer to the Sun than Earth, making this order incorrect.

In conclusion, Option 3 accurately reflects the order of planets based on their distance from the Sun: Mercury, Venus, Earth, Mars. This order is supported by astronomical observations and measurements of the planets' orbits.
