The Milky Way galaxy does not spin as a unit, but the best answer is probably this: It takes around 220 million years for the Sun to make a complete trip around the galactic core (obviously, that's an estimate, since we haven't actually been watching for even a millionth of that time yet).

What would happen to the length of the day if you had no atmosphere?
Nothing - the length of 'day' on any planet - is the time it takes to revolve once on its axis. Relating to the Earth - that's approximately 23 hours 56 minutes.
What is a planet period of rotation?
A planet's period of rotation refers to the time it takes for the planet to complete one full rotation on its axis. This is what determines the length of a day on that planet. For example, Earth's period of rotation is approximately 24 hours, which is why we have a 24-hour day.
Time of planet rotation?
The time it takes for a planet to complete one full rotation on its axis varies depending on the planet. For example, Earth takes approximately 24 hours to rotate once, while Venus takes about 243 Earth days. The length of a day on a planet is determined by its rotational speed and size.
What planet is the fastest rotating planet?
Jupiter is the fastest rotating planet int he solar system.
What event occurs once every 24 hours?
Planet Earth completely rotates on its axis once every 24 hours, thus making the appearance of the sun rising.
What is the name for the length of time it takes a planet to spin once on its axis?
Its rotational period.
What is the name for the length of time it takes a planet to spin once its axis?
Rotational Period .
What is the name for the length of time it takes a planet to spin once on it's axis?
Its rotational period.
Uranous- length of days and years?
Uranus rotates on its axis (its 'day') once every 17.2 hours.The planet revolves around the sun (its 'year') once every 84 earth years.

What causes a day on a planet?
A day is defined as the time it take a planet to revolve once on it's axis. So it is the time it takes for a planet to "spin" once.
What is the planet that rotates on its axis once in 243 earth days?
Venus
Length of one planetary day on Uranus?
The planet Uranus spins on its axis just a little slower than once every 17 hours. Because the axis of the planet is sideways in relation to its orbit, (Uranus spins on its side), daylight lasts for about earth 70 days, and darkness last for about earth 70 days.
What is the difference between a planet's period of rotation and period of revolution?
All planets in our solar system vary in the time it takes them to complete a revolution. This is due to their differing distances from the sun. As far as rotation goes, the time varies from nine hours and fifty minutes for Jupiter to 244 days for Venus to make a like rotation.
When does a planet complete a full circle?
It revolves around the sun once a year and rotates around its axis once a day.
What is the rotational period of the planet earth?
The Earth takes 23h56m to rotate once around its axis.
