Identifying X in the sequence of planets

To identify the missing planet X in the given sequence of planets (Mercury, Venus, X, Mars), we need to analyze the order of the planets in our solar system and find the missing planet that fits between Venus and Mars.

Understanding the sequence of planets

1. Mercury: Mercury is the closest planet to the Sun and is the smallest planet in our solar system.

2. Venus: Venus is the second planet from the Sun and is known for its thick atmosphere and hot surface temperature.

3. X: This is the missing planet that we need to identify.

4. Mars: Mars is the fourth planet from the Sun and is known for its reddish appearance and the presence of ice caps.

Eliminating the incorrect options

a) Saturn: Saturn is the sixth planet from the Sun, so it does not fit between Venus and Mars. Therefore, option 'a' can be eliminated.

Evaluating the correct option

b) Earth: Earth is the third planet from the Sun and is known for its diverse ecosystems and the presence of liquid water. It fits perfectly between Venus and Mars in the sequence of planets. Therefore, option 'b' is the correct answer.

c) Jupiter: Jupiter is the largest planet in our solar system and is the fifth planet from the Sun. It does not fit between Venus and Mars, so option 'c' can be eliminated.

d) Uranus: Uranus is the seventh planet from the Sun and is known for its unique tilted axis of rotation. It does not fit between Venus and Mars, so option 'd' can be eliminated.

Conclusion

Based on the analysis of the sequence of planets and their order in the solar system, option 'b' (Earth) is the correct answer for the missing planet X between Venus and Mars.
