Mercury rotates once in its axis once every 58 days 15 hrs and 30 min. In terms of earth hours that's 1407.5 hrs.
9.9 Earth hours
One day (or one rotation around its axis) takes 1407.6 Earth hours.
The rotation period of Neptune is 16.1 earth hours.
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. :)
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.)
A Mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours.
It is 1408 hours.
24 hours
Mercury has a rotation period of 58.646 days.
9.9 Earth hours
A mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours.
its revolution period is 687 (Earth) days.And its rotation period is 24 hours, 39 minutes
16.1 hours
One day (or one rotation around its axis) takes 1407.6 Earth hours.
The rotation period of Neptune is 16.1 earth hours.
Rotation means the planet spinning about it axis. (Orbit the the path of the planet round the Sun). The planet Mercury has a rotational period of 58.646 Earth days. The planet Venus has a (retrograde) rotational period of 243.0185 Earth days. The planet Mars has a rotational period of 1.025957 Earth days. The planet Jupiter has a rotational period of 9.925 hours. Obviously Earth has a rotational period of 1 Earth day.
The period of earth's rotation on its axis is 23hours56minutes4seconds of mean solar time.
