Mercury is the smallest planet in our solar system.

It is the closest planet to the sun.

One day on Mercury (the time taken to rotate on its axis) = 59 Earth days.

One year on Mercury ( the time taken to go round the sun) = 88 Earth days.

So on Mercury one year is 1.5 days.

Day temperature (when Mercury faces the sun) is 430�C.

Night temperature (when Mercury faces away from the sun) is -180�C.
