- On Mercury a day lasts twice as long as a year. NASA/JHUAPL. Technically, one Mercurian day lasts 59 Earth days, while a year lasts 88. However, due to Mercury’s very eccentric orbit and alignment with the Sun, the length of time from sunrise to sunrise, known as a ‘solar day’, is equal to 176 Earth days — twice as long as a Mercurian year.
