Mercury is the second smallest planet in our Solar System after pluto. It’s a dry, rocky and barren world with extreme temperatures.Its surface is marked with craters heavily just like moon. As its closest to the Sun, so it has the fastest orbit, taking just 88 days to complete on revolution around the Giant star. Despite its such fast orbit, surprising Mercury moves very slowly on its axis, taking 59 days to make one full revolution ( giants as Jupiter take under 10 hours !! ) This means that two thirds of the way through its orbit, Mercury has only completed one revolution on its axis. This effect, combined with Mercury’s very thin atmosphere, produces dramatic temperature ranges on its surface. Here are some of its figures :-

Diameter	4878 km
Average Distance from Sun	57.8 million km
Size compared to Earth	0.4x
Gravity compared to Earth	0.38
Surface Temperature	Max Day Side 467°C Min Night Side -183°C
Length of day	58 (Earth) days 16 hours
Length of year	87.9 days
Eccentricity of Orbit	0.206
Density	5.43 g/cm³
Atmosphere	Oxygen - 56% Sodium - 35% Helium - 8% Potassium & Hydrogen - 1%
