Question

A spacecraft cannot land on Venus because it is the ___________.
     A) Smallest planet
     B) Coldest planet
     C) Hottest planet
     D) Densest planet

Answer 1

Hint: The planet Venus has a very thick atmosphere which traps the sun’s heat and does not let it escape. This makes Venus the hottest planet in the solar system. For a spacecraft to land properly on a planet and be operational, all the electronics must work properly.

Complete answer:
The planet Venus is the hottest planet in our solar system even though it is not closest to the sun. This is because Venus has a thick atmosphere which traps the heat of the sun and does not let it escape.
If a spacecraft were to land on Venus, the high temperatures would burn up the rocket and damage the electronics inside the rocket within seconds. Hence, the rocket would not remain operational and would get destroyed within seconds of the hypothetical landing on Venus.
Therefore, the spacecraft cannot land on Venus because it is the hottest planet.

Therefore, the correct option is C) Hottest planet.

Note:
Students must be thinking that since Venus is a very small planet, that is why some complications might arise during landing of spacecraft. However, they must realize that the size of the spacecraft is negligible in comparison to the size of the planet and thus has no considerable effect on the landing of a spacecraft. In fact, human made spacecraft have already landed on the moon which is about six times smaller in terms of the diameter than Venus.
