Which of the following is a group of inner planets ?

Question

Accepted Answer

Option 2, "Venus, Earth, Mercury, Mars," is the correct answer because it accurately lists the group of inner planets in our solar system. The inner planets, also known as terrestrial planets, are those that are closest to the Sun and have solid, rocky surfaces. Let's explore why Option 2 is correct and why the other options are incorrect:

1. **Explanation for Option 2:**
   - **Mercury, Venus, Earth, and Mars** are the four inner planets. They are located between the Sun and the asteroid belt, which separates them from the outer planets.
   - These planets are characterized by their rocky surfaces and are smaller in size compared to the gas giants of the outer solar system.
   - They have relatively shorter orbits around the Sun and lack the extensive ring systems found in the outer planets.

2. **Why the other options are incorrect:**
   - **Option 1: Mercury, Venus, Earth, Jupiter**
     - Jupiter is not an inner planet; it is a gas giant and part of the outer planets. It is located beyond the asteroid belt, which disqualifies this option from being a correct list of inner planets.
   - **Option 3: Earth, Mars, Venus, Jupiter**
     - Similar to Option 1, this option incorrectly includes Jupiter, which is not an inner planet. The presence of Jupiter makes this option incorrect.
   - **Option 4: Earth, Mars, Jupiter, Saturn**
     - Both Jupiter and Saturn are gas giants and part of the outer planets. Their inclusion in this option makes it incorrect for identifying the group of inner planets.

In conclusion, Option 2 is the only option that correctly lists all the inner planets: Mercury, Venus, Earth, and Mars. The other options include planets that are not part of the inner solar system, which is why they are incorrect.
