Did you know? - Mercury

January 1, 2018


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.
