In a rotating solid body, regions that are adjacent at one point in time will remain adjacent as the body rotates. This means that points further from the rotation centre will travel at greater speeds than those closer in. If the rotating body is not solid, however, regions that are adjacent at one point in time do not necessarily maintain that configuration. This is known as 'differential rotation'.
Examples of differential rotation are found throughout astronomy. In stars (including the Sun) and the gas giant planets, the equatorial regions rotate faster than regions closer to the poles, meaning that equatorial sunspots and cloud formations will move across the face of the object faster than their polar cousins.In the Solar System, the outer objects feel less of a gravitational pull from the Sun. They must therefore orbit at slower speeds than the inner objects in order to maintain their orbital radius. This is known as Keplerian Rotation and results in the inner objects overtaking and racing ahead of the outer objects.In the disks of spiral galaxies, all of the material orbits at roughly the same speed. However, the outer stars have further to travel in their orbit around the galactic centre than the inner stars. The result is that the outer stars lag behind the stars in the inner reaches of the galaxy.All objects in the disk of a spiral galaxy are moving at roughly the same orbital speed. Since the outer objects have further to travel in their orbits than the inner ones, they lag behind.
What else can I help you with?
What kind of rotation does Mercury have?
Mercury has a oval rotation because of the suns gravity
What is relation between sun differential rotation and core rotation of earth?
The weird thing about the Sun's rotation - as compared to Earth's rotation - is precisely that it is a differential rotation. That means that at the equator, the Sun rotates faster than near the poles. There is some recent evidence that the inner and outer cores of Earth do indeed spin at different rates and at different rates compared with the rest of the planet.
How long does it take the sun to rotate once?
The Sun has a differential rotation, caused by Coriolis forces. Near the equator, one rotation takes about 25 days; near the poles, one rotation takes about 34 days.
Where is the starting point of the suns rotation?
The starting point of the sun's rotation is typically considered to be the equator of the sun. The sun rotates on its axis, which passes through its equator, completing a full rotation approximately once every 27 days.
The circulation of gases in the sun combines with the suns rotation to create what?
The circulation of gases in the Sun, along with its rotation, creates magnetic fields. These magnetic fields are responsible for various phenomena such as sunspots, solar flares, and the solar wind.
How long does it takes for sun to rotate once?
Strangely, the Suns has a differential rotation. At the equator, it takes 25 days for one rotation; near the poles, 34 days.
What is is the suns rotation?
25 days
What kind of rotation does Mercury have?
Mercury has a oval rotation because of the suns gravity
How long is the suns rotation?
25 days for a rotation at the equator, 34 days for a rotation near the poles.
What dis the suns period of rotation?
Approximately 24.47 days
What is the rotation's name where bands move at different speeds?
That rotation is called differential rotation, where different bands within a rotating object move at varying speeds relative to one another. This phenomenon is often observed in celestial bodies like the Sun, where differential rotation causes the equator to rotate faster than the poles.
What is relation between sun differential rotation and core rotation of earth?
The weird thing about the Sun's rotation - as compared to Earth's rotation - is precisely that it is a differential rotation. That means that at the equator, the Sun rotates faster than near the poles. There is some recent evidence that the inner and outer cores of Earth do indeed spin at different rates and at different rates compared with the rest of the planet.
What is differential in pickup trucks?
The differential, often referred to as the "rear", is the gear housing which transmits the rotation of the driveshaft to the rear wheels. A four-wheel drive truck also has a differential for the front wheels.
How long does it take the sun to rotate once?
The Sun has a differential rotation, caused by Coriolis forces. Near the equator, one rotation takes about 25 days; near the poles, one rotation takes about 34 days.
What is the significance of differential rotation in the dynamics of celestial bodies?
Differential rotation is important in the dynamics of celestial bodies because it causes different parts of a body to rotate at different speeds. This can lead to the formation of magnetic fields, atmospheric circulation patterns, and other phenomena that influence the behavior and evolution of celestial bodies.
What is it called when an object has different rotation rates for different latitudes?
This phenomenon is called differential rotation. It occurs when an object rotates at varying speeds depending on its latitude, with the equator typically rotating faster than the poles. This is commonly observed in astronomical bodies such as the Sun and gas giants like Jupiter.
What causes the belts and zones in Jupiters atmosphere?
The belts and zones of Jupiter result from the planet's convetion and it's rapid differential rotation.
