# Does Uranus have differential rotation?

## Does Uranus have differential rotation?

Saturn 10h 20m; Uranus 16h 33m; Neptune 17h 16m. Because they have no solid surface, they all experience differential rotation (the equators rotate more rapidly than the poles).

Why does the Sun have differential rotation?

Internal rotation in the Sun shows differential rotation in the outer convective region and almost uniform rotation in the central radiative region. Differential rotation is caused by convection in stars. The movement of mass is due to steep temperature gradients from the core outwards.

Which of the following plants has a lesser rotation time than the earth?

Venus is closer to the Sun; therefore, its orbit takes a shorter period of time than its rotation upon its axis.

### How is the differential rotation of Uranus unusual?

Uranus is an oddball in the solar system. Its rotational axis is tilted by almost 90 degrees, like a spinning top lying on its side. One lap around the sun takes about 85 years.

Does Saturn rotate differential?

Galaxies and protostars usually show differential rotation; examples in the Solar System include the Sun, Jupiter and Saturn.

Is Saturn the only planet with rings that orbit it?

Saturn is the sixth planet from the sun. True, it’s not the only planet with rings. Jupiter, Uranus and Neptune have rings, too. But Saturn’s rings are the biggest and brightest.

#### What differential rotation is in the Sun?

Differential rotation of the Sun The Sun has an equatorial rotation speed of ~2 km/s; its differential rotation implies that the angular velocity decreases with increased latitude. The poles make one rotation every 34.3 days and the equator every 25.05 days, as measured relative to distant stars (sidereal rotation).

Does the earth have differential rotation?

The “effective” rotation of Earth thus increases as we move poleward, and thus Earth’s atmosphere and ocean are said to be in differential rotation. We take this effect into account by allowing the Coriolis parameter, f, to equal twice the vertical component of the rotation.

Which planet has fastest revolution time?

Answer: Mercury is the winner at an orbital speed of about 47.87 km/s (107,082 miles per hour), which is a period of about 87.97 Earth days.

## Which has the longest revolution time?

A Year On Neptune: Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).

How does Neptune rotate?

One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once). Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the Sun, which is similar to the axial tilts of Mars and Earth.

What is Pluto tilt?

Its axis of rotation is tilted 57 degrees with respect to the plane of its orbit around the Sun, so it spins almost on its side.

### Which is an example of a differential rotation?

This indicates that the object is not solid. In fluid objects, such as accretion disks, this leads to shearing. Galaxies and protostars usually show differential rotation; examples in the Solar System include the Sun, Jupiter and Saturn. Around the year 1610, Galileo Galilei observed sunspots and calculated the rotation of the Sun.

Which is the only planet that rotates in the opposite direction?

Retrograde rotation is in the opposite direction. Most planets in our solar system, including Earth, rotate counter-clockwise or prograde direction, but Venus and Uranus are said to have a retrograde or clockwise rotation around their axes.

Is the rotation of the Sun uniform or differential?

Internal rotation in the Sun, showing differential rotation in the outer convective region and almost uniform rotation in the central radiative region. On the Sun, the study of oscillations revealed that rotation is roughly constant within the whole radiative interior and variable with radius and latitude within the convective envelope.

#### How does differential rotation work in a solid body?

Differential Rotation. 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…
