Mercury
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.
