Whereas Venus is the second planet from the Sun and it orbits the Sun after every 224.7 Earth days which means the rotation period of this planet is more than the revolution period. It is the brightest natural object in the night sky as well. Venus is classified as a terrestrial planet and it is sometimes called Earth’s “sister planet” due to the similar size, gravity, and bulk composition.
