Detailed explanation-1: -The period of rotation of Venus on its own axis is about 243 Earth days, while the period of revolution of Venus around the Sun is about 225 Earth days. Moreover, Venus spins in backwards direction when compared to most other planets. This means that the Sun rises in the West and sets in the East at Venus.
Detailed explanation-2: -An explanation for the backward, or retrograde, rotation is not certain. A long-held theory is that Venus once rotated as the other planets do, but was struck billions of years ago by a planet-size object. The impact and its aftermath caused the rotation to change directions or flipped the planetary axis.
Detailed explanation-3: -The rotation of planets Venus and Uranus on their axes, is somewhat unusual. They rotate from the East to the West, while all other planets rotate from the West to the East.
Detailed explanation-4: -Assertion :Sun rise and Sun set as seen from the planet Venus will be in the West and East direction respectively. Reason: Venus rotates from East to West.
Detailed explanation-5: -Venus is the hottest planet with a temperature of about 450 degrees to 500 degrees Celsius. Venus is not only close to Mercury but also has a similar temperature (Mercury’s temperature ranges from 400 to 450 degrees C). Venus repels Mercury away due to like charges. This makes Venus rotate from East to West.
