Question

The coldest planet is:

• A. Neptune
• B. Jupiter
• C. Uranus
• D. Saturn

Answer 1

The correct option is A

Neptune

1. The intensity of solar radiation decrease as we move away from the sun.
2. Therefore planets that are away from the sun receive less solar energy.
3. Neptune is the farthest from the sun, as a result, it receives the least amount of solar radiation from the sun due to which temperature plummets to$-200°C$.

Hence, option D is correct.
