mercury, it only takes 88 days. The closer the planet is to the parent star (sun in our case) the less time it takes to complete one orbit. Mercury is the closest planet to the sun and the planet to take the shortest time to orbit it.
The moon takes about 27.3 days to spin around its axis once, which is the same amount of time it takes to complete one orbit around Earth. This synchronous rotation is why we always see the same face of the moon from Earth.
Mercury has the longest "solar "or apparent day. Mercury takes 88 Earth days to go around the Sun, so its year is 88 Earth days. It spins very slowly on its axis though, once every 58.6 Earth days days relative to background stars. A solar (apparent) day on Mercury takes 176 Earth days, because of this slow spin relative to the time taken to orbit.The spin of Venus relative to the background stars is slower, taking 243 Earth days to spin once on its axis. But since its spin is retrograde (clockwise as viewed from above the north pole) and in the opposite direction of orbit around the sun, the apparent solar day is less, at 116.75 days.So, Mercury has the longest "Solar day". However Venus has the longest "sidereal day", because that's defined as the rotation period.
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.
Mercury has a shorter year than Earth, since it orbits the sun in less time. Mercury takes 88 days to go around the sun, so its year is 88 solar days. It spins very slowly on its axis though, once every 58.6 days relative to background stars. An `apparent day` on Mercury takes 176 days in total though, because of this slow spin relative to the time taken to orbit.
Mercury does not spin as fast as Earth, so a Mercurian day (the time it takes a planet to rotate once) is 59 Earth days.
the answer is 88 days ,making 88 earth days 1 mercury year
88 days
Mercury to orbit around the Sun; a typical year on Mercury would take 88 Earth days. Because of Mercury's ever changing distance from the sun and its 3:2 spin-orbit resonance the temperature on Mercury's surface is complex and varied.
It takes Mercury about 59 Earth days to complete one full rotation on its axis. This means that a day on Mercury (one full rotation) is equivalent to 59 Earth days.
A Mercurian "day" the (time it takes it go spin once on it's axis) is equal to 58.65 earth days. Mercury turns on it's axis very, very slowly.
27.32 days
The answer is 58.646 day.
It takes one month for the moon to spin on it's axis.
Mercury is weird. It circles the sun every 88 days, and takes 58.6 days to rotate once on its axis !That's 1,406 hours .
It takes Mercury much longer than planet Earth to make a complete spin on its axis. Mercury rotates once every 1407 hours or 58 days.
Because of the periods of Mercury's orbit and spin, a year (complete orbit around the sun) on Mercury is about 88 Earth days long, while a day (time for the Sun to appear in the same place in the sky) is twice that length, at about 176 Earth days long.
