In the time it takes Mercury to complete one rotation, Neptune rotates 87.37 times.
Mercury has the shortest rotation period, taking about 59 Earth days to complete one rotation. Venus has an unusual rotation period of about 243 Earth days, which is longer than its orbital period around the Sun. Earth rotates once every 24 hours, while Mars has a rotation period of approximately 24.6 hours. Thus, the sequence from shortest to longest rotation periods is Mercury, Earth, Mars, and then Venus.
Mercury takes about 59 Earth days to complete one rotation on its axis. This is longer than its orbital period around the sun, which is about 88 Earth days.
There are 59 (Earth) days in a day on Mercury. That is 1416 hours. * * * * * If you are going to go down to the level of hours, make sure the figure for days is sufficiently precise. A mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours. However, because of Mercurys slow rotation, one full day - sunrise to sunrise takes two Mercury years. So a full day is 87.9691 x 2 = 175.9382 Earth days or 4,222.5168 hours A daylight day is one Mercury year or 2,111.2584 Hours ravenjaja:there are 1416 hours in a day on mercury.believe us. :)
Ceres' period of rotation is approximately 9 hours, which is significantly shorter than Earth's rotation period of about 24 hours. This means that Ceres completes one full rotation on its axis much faster than Earth does.

A Mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours.
The smallest planet, Mercury, has a period of rotation of about 59 Earth days. Its slow rotation speed means that a day on Mercury (from one sunrise to the next) is much longer compared to a day on Earth.
It is 1408 hours.

Venus spins the slowest among these planets, taking around 243 Earth days to complete one rotation. Mercury is next, with a rotation period of about 59 Earth days. Earth and Mars have relatively similar spin rates, with Earth taking about 24 hours and Mars around 24.6 hours to complete one rotation.
24 hours
Mercury has a rotation period of 58.646 days.
Ceres' period of rotation is approximately 9 hours, which is significantly shorter than Earth's rotation period of about 24 hours. This means that Ceres completes one full rotation on its axis much faster than Earth does.
9.9 Earth hours
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.)
