The inner planets are :

Question

Accepted Answer

The inner planets are defined as those planets that are located between the Sun and the Belt of Asteroids. This is why Option 4 is the correct answer. Let's delve into the reasoning:

1. **Explanation for Option 4 (Correct Answer):**
   - The inner planets, also known as terrestrial planets, include Mercury, Venus, Earth, and Mars. These planets are situated between the Sun and the Asteroid Belt, which lies between Mars and Jupiter. This region is characterized by rocky planets with solid surfaces, distinguishing them from the outer planets, which are primarily gaseous. The Asteroid Belt serves as a boundary separating the inner planets from the outer planets in our solar system.

2. **Why Option 1 is Incorrect:**
   - Option 1 suggests that the inner planets are satellites of planets. This is incorrect because satellites, or moons, are natural bodies that orbit planets. The inner planets themselves are not satellites; they are independent planets orbiting the Sun.

3. **Why Option 2 is Incorrect:**
   - Option 2 describes the inner planets as gaseous planets. This is incorrect because the inner planets are terrestrial, meaning they have solid, rocky surfaces. In contrast, gaseous planets, such as Jupiter and Saturn, are part of the outer planets and are composed mainly of gases like hydrogen and helium.

4. **Why Option 3 is Incorrect:**
   - Option 3 states that the inner planets are those between the Sun and Earth only. This is incorrect because it excludes Venus and Mars, which are also considered inner planets. The definition of inner planets includes all planets from Mercury to Mars, not just those between the Sun and Earth.

In conclusion, Option 4 accurately describes the inner planets as those located between the Sun and the Belt of Asteroids, encompassing Mercury, Venus, Earth, and Mars. This definition aligns with the established understanding of our solar system's structure.
