» Mercury planet has no gases like CO2, N2, H2 and O2 which can act as building blocks of life.
» Mercury planet has no protective blanket like Ozone around it to prevent us from harmful radiations.


» Venus is the second planet in distance from the Sun. This planet is nearest to the Earth and is also the brightest planet.
» Venus is known as the 'Evening Star' as well as 'Morning Star'.
» Venus is surrounded by a thick cloud cover, hence known as the Veiled Planet' ('veil' means unclear/cover).

» Venus is the hottest planet (even hotter than Mercury) of our Solar System, due to its veil of cloud.
» Venus has no water on it. There is no sufficient oxygen on the Venus.
