It s the hottest planet in our solar system even though mercury is closer to the sun. Venus has been called earth s twin because of the similarities in their masses sizes and densities and their similar relative locations in the solar system. From the surface of mercury the sun would appear more than three times as large as it does when viewed from earth and the sunlight would be as much as seven times brighter.

The images used to create this view were acquired by mariner 10 on feb. It has a solid surface that is covered with craters like our moon.

Because they presumably formed in the solar nebula from the same kind of rocky planetary building blocks they also likely have similar overall chemical compositions early telescopic observations of the planet revealed a perpetual veil.

Temperatures go up to 500 c when it faces the sun and 150 c on its dark side. It takes mercury about 88 days to go round the sun once and one mercury day is about 58 earth days long. Mercury is the first planet in the solar system only about 60 million km away from the sun.
