Question

Which planets rotate from east to west?
A. Venus, Uranus
B. Uranus, Jupiter
C. Mercury, Mars
D. Neptune, Earth

Answer 1

Hint: The planets in our solar system are rotating from west to east, whereas only two planets have rotation from east to west. Scientists say that one major reason behind this rotation is the gravitational pull on these planets due to the moon and another one reason is strong asteroid hit.

Complete step by step solution:
The planet Uranus had a large moon in the past, the gravitational pull from that moon on the planet caused the planet to fall on its side. After that, the moon moves to another planet like a pinball. As for the planet Venus, scientists explained that initials start to rotate counter-clockwise and tend to be static for a period then rotates in the direction as of now.
This will explain that the very slow rotation of the planet today – the planet Venus takes $243$ Earth days to complete one full rotation, but only $225$ Earth days to revolve the Sun. So, if you are living on the planet Venus, your days must be longer than your years (and the Sun might rise in the west direction). The Sun's strong gravitational pull acts on the dense atmosphere of Venus; the atmospheric tides that will create around the planet, that tidal force could all have combined to reverse the planet's rotation.
The phenomenon of tidal torque – where the compact atmosphere on the hot, Sun-forced side of a planet is back away from the cold side – is one of the clearest explanations for Venus' reverse rotation, in addition to the planetary collision. Till now, no scientists are clear about the reverse rotation of the planets Venus and Uranus.

$\therefore$ Venus and Uranus are the planets that rotate from east to west. Hence the option (A) is correct.

Note:
Venus is the planet that is closer to the sun than the Earth. So, the gravitational tidal force of the sun on the planet Venus, slows down the planet rotation. In addition, the atmospheric tidal forces on Venus also drive, so it turns very slowly in the reverse direction. The pole points at the sun of the planet Uranus is tilted. That involves the planetary collision. Hence, it tends to the reversal rotation of planet Uranus.
