Mercury spins very slowly on its axis, only once every 58.6 Earth days (relative to background stars).
However, the comparatively short Mercury "year" (just 88 Earth days) has dramatic consequences for the length of the "solar day" -- sunrise to sunrise -- on the planet. A solar (apparent) day on Mercury takes 176 Earth days, which is effectively twice the length of the year. Basically, as the planet is turning, the motion around the Sun is counteracting the effect. (We see something similar on Earth, where the Moon's west-to-east orbit keeps it in the night sky longer than any of the stars.)

Actually, astronomers call this the "period of revolution".

What planet has the second shortest day?
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
What is the time for mars to spin once?
The sidereal rotation period of Mars - one spin on its axis relative to background stars, is 24.623 hours. This is very similar to the earths sidereal rotation period.
Mercury rotation on its axis?
Period of rotation is about 58.65 Earth days.
Compare the period of revolution between mercury and plutowhat is the ratio between their period of rotation and why?
IT IS not The same Period of rotation Because tthe mercury have rotation g9 days and the pluto have a rotation 6.4 days so it is not the same BY:JULLIA TUTANES :P
