Question

The hottest planet in the solar system is}

• A. Earth
• B. Mars
• C. Venus
• D. Jupiter

Hint:

Remember: Mercury is closest to the Sun, but Venus is the hottest due to the greenhouse effect—this is a common exam trap.

Answer 1

The Correct Option is C

Concept: The temperature of a planet depends not only on its distance from the Sun but also on its atmospheric composition and heat-trapping ability. Step 1:Compare planetary heating mechanisms.
Mercury receives intense solar radiation but lacks an atmosphere to retain heat, causing rapid cooling. In contrast, Venus has a very dense carbon dioxide-rich atmosphere that traps heat effectively.
Step 2:Understand the greenhouse effect.
The thick atmosphere of Venus prevents heat from escaping, leading to extreme surface temperatures around: \[ \sim 470^\circ \text{C} \]
Step 3:Evaluate other options.

• Earth → Moderate temperature due to balanced atmosphere
• Mars → Thin atmosphere leading to cold conditions
• Jupiter → Gas giant with no solid surface temperature comparison

Final Answer: Venus
