Question

On which planet, the sun sets in the east?
(A). Saturn
(B). Venus
(C). Mercury
(D). Pluto

Answer 1

Hint: To determine if the sun sets in the east or west, we need to find out the direction of rotation of the planet. It must be rotating opposite to the rotation of the Earth as the Sun sets in the west on Earth. i.e. the planet must be rotating in the clockwise direction.

Complete step by step answer:
Venus is the second planet from the sun and closest to us. We can see Venus as a star at the horizon at dawn. Venus is also called ‘Earth’s sister planet’ as it is closest in size to Earth. Venus completes its one revolution in 224.7 Earth days but completes one rotation in 243 Earth days and that too in opposite direction. Due to which its 1 year completes before its one day.
Venus is the only planet in our universe which revolves in the opposite direction as all the other planets. This means that in almost all the planets the sun sets in the west, in Venus and Uranus the sun sets in east.

So, the correct answer is “Option B”.

Additional Information: Mercury, Venus, Earth, Mars are made up of rocks and metals and hence called terrestrial planets while, Jupiter, Saturn, Uranus and Neptune are made up of gases.

Note: All planets in the universe rotate in the anti-clockwise direction except Venus which rotates in the clockwise direction. The rotation of Venus is very slow due to which its orbit is almost spherical. Venus has no moons or natural satellites. It is the hottest planet in the solar system.
