How long does mercury take to complete a full day?
A whole day on mercury is 58 days, which is strange because a whole year for mercury is only 88 days. Improved answer: It's stranger than that. Mercury rotates in about 58 Earth days and that's called a sidereal day. However there is also the "solar day". That is to do with how long the Sun takes to, apparently, move round the sky. That depends on both the spin and orbital motion of a planet. For Mercury the solar day is about 176 Earth days. That's TWICE the length of the year.
