The length of a day on a planet is how long it takes to spin on its axis. The length of a day on Mercury is 58 days and 15 hours in Earth time. A day on Venus is 243 Earth days, Mars is 24 hours 39 minutes and 35 seconds, Jupiter's day is 9.9 Earth hours, Saturn is 10 hours and 47 minutes, Uranus is 17 hours 14 minutes and 24 seconds, and Neptune's day is 16 hours 6 minutes and 36 seconds.
The length of time it takes to complete one full rotation
each planet has a different amount of time i takes to rotate around the sun so all i can say is that the closer you are te shorter and the farther you are the longer:)
One rotation
It depends on which one. Ours is 24 hours, but a day is different elsewhere dependant on size & rate of rotation
The period can refer to one of two things: the planets rotation about its axis (how long its day is) and the rotation around its star (how long its year is).
One day
one day
The Earth rotates on its axis in one day. Strictly speaking that's the "sidereal day" not the "solar day". Also, by definition, each planet rotates once in a period that's the "sidereal day" for that particular planet.
59 day noy are uahppy
This is planet Earth, so one Earth day is one day on this planet.
30.5 the same as deimos30.5 what?Phobos and Deimos are both moons of the planet Mars.
The length of time it takes to complete one full rotation
one to two pounds each day.
Yep! All planets do, one day happens after each individual planet spins around completely while orbiting the sun! Each day for each planet is different! Some other planets have days that are 243 Earth days to 10 hours! Hope that helps!!
It is 9 months
The length of a day on the planet Mars is 24 hours and 37 minutes. One year on the planet is equal to 680 days on Earth.
It depends on which planet your talking about, for example if your talking about Earth its about 24 hours.
