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.)

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.
What is the ratio of the period of rotation between mercury and Neptune?
In the time it takes Mercury to complete one rotation, Neptune rotates 87.37 times.
What is Mercury's period of rotation and revolution?
Mercury's period of rotation, or the time it takes to complete one full rotation on its axis, is 58.6 Earth days. Its period of revolution, or the time it takes to orbit the Sun, is about 88 Earth days. This means that one day on Mercury (rotation) is longer than one year on Mercury (revolution).
Which planet's day is closest in length to its year?
The planet Mercury has a day that is almost the same length as its year. Mercury's rotation period is about 59 Earth days, which is very close to its orbital period around the Sun of about 88 Earth days. This means that one day on Mercury is almost as long as one year on Mercury.
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.
