A day on the planet Mercury is twice as long as its year.

 

Mercury rotates very slowly but orbits the Sun at 180,000 km/h

 

Mercury orbits the Sun in slightly less than 88 days

 

 

Its interesting to compare: 

 

The Earth orbits the Sun in 365 days at an average speed of 107,220 km/h

 

The fastest known Neutron star rotates over 700 times in one second.
