How does a planet revolves on it's axis?
For the purposes of this question we will consider a planet as a solid body - which it pretty much is anyways. As a result of a planet's formation it is left with some rotational energy. This is merely a result of chaotic systems and it would be extremely difficult to have a body with exactly zero rotational energy. Since the planet is a solid body it has to turn uniformly- an as it turns uniformly there has to be an axis of rotation, a line through the body around which it turns. If a planet is a long ways away from it centre of orbit the tidal forces are negligable and there is no impediment to it rotation. All the planets Earth and beyond rotate with a period different from their period of orbit. Venus and Mercury are tidally locked with their solar orbital period in some resonance ratio. Earth's moon and most planetary moons are like-wise tidally locked with a period similar to their orbital period. It has been proposed that Uranus was hit by some massive object that alterned its axis of rotation to an extreme degree. If this is true the mass and energy of the object must have been considerable.
How is revolution and rotation of planets the same?
revolution-is the revolving of an object around another object. rotation-is the spinning of an object on its axis. revolution and rotation are two different concepts but, are alike in some way. Rotation- Dominic
Which planet is tilted on its side as it orbits the sun?
The planet Uranus is tilted "on its side" about 98 degrees to the orbital plane. But all planets in our solar system have some tilt to the side, including Earth which tiles about 23 degrees. (Mercury's tilt is very small.)
What planet has a moon that is a big as it self?
None. Some of the moons of Jupiter are nearly the size of Mercury, but no planet has a moon as big as the planet itself.
What is the length of Saturn's daily rotation?
The Overall Rotation of the PlanetSince Saturn does not have a solid surface, it is difficult to define a rotation period for the planet as a whole. Different portions of its visible "surface", which represent different circulation systems in its atmosphere, move around its axis at different rates, according to whether they have westward or eastward motions relative to the overall rotation of the planet. "System I", which refers to the Equatorial region, has a rotation rate of around 10 hours 14 minutes, while "System II", which refers to non-Equatorial regions, has a rotation rate of around 10 hours 39 minutes. There is also a "System III" rotation, which refers to the rate of rotation of the planet's radio emissions, which was once thought to refer to the rotation of the "body" of the planet, and at the time of the Voyager flybys, was around 10 hours 39 minutes. However, in the years since then, the System III rotation period has increased to 10 hours 45 minutes, indicating that it is not associated with the "real" rotation of the planet. Alterations in the position of the radio field, and in the plasma field surrounding the planet (possibly caused by geyser eruptions on Enceladus), are thought to be responsible for the change in the System III rotation rate; but whatever the cause of these changes, they cannot be due to a change in the rotation of the body of the planet. So the once-hoped-for fundamental nature of the System III rotation period has been disproved, and there is no currently conceivable way of estimating the "real" rotation of the planet as a whole. A recent compilation of results yields a rotation period of 10 hours 32 minutes 35 seconds; but this value is like the proverbial two point something children per American family -- it may be mathematically useful, but it cannot be representative of any real family, since no family can contain a fraction of a child. In the same way, the compiled rotation period may be useful for some calculations (e.g., the comparison of roation period and day length mentioned below), but it has no correspondence to any real part of Saturn.Regardless of these uncertainties, there is no doubt that Saturn has the second-fastest rotation rate of any planet, both in terms of its rotation period, and the speed of its rotation at the Equator, which is just under 10 kilometers per second, or about 35000 kilometers per hour (or just under 6 miles per second, or about 22000 miles per hour). Only Jupiter has a faster rotational velocity or rotation period.Difference Between Rotation Period and Day LengthSince the rotation period of Saturn is so uncertain, the difference between its rotation period and day length is, for all practical purposes, unimportant; but as discussed at Rotation Period and Day Length, given its rapid rotation and long orbital period, the difference between the two values is only about one second. So no matter where you are on Saturn, whatever the local rotation period is, the length of the day is one second longer.The Rotational Tilt of SaturnThe axis of Saturn's rotation is tilted relative to its orbit by just under 27 degrees. This means that insofar as Saturn has seasons, they would be similar to those on the Earth, being relatively minor at the Equator, relatively extreme at the Poles, and in-between at in-between latitudes. However, since Saturn's temperature is over 200 degrees below zero Fahrenheit, even its warmest summers are very cold by Earthly standards, and seasons as we know them do not exist.Despite the lack of obvious seasonal effects, the tilt of Saturn's axis does produce a very easily observable effect, because the ring system of the planet and the orbits of virtually all of the planet's moons are very closely aligned to the planet's Equatorial plane. Therefore, as discussed at The Rings of Saturn, when we see Saturn near one of its polar summers, we see the rings from above or below, as a broad, spectacular oval; whereas when we see Saturn near the start of its spring or fall (as we do in 2008 and 2009), the rings are barely visible, due to our nearly edge-on view
On which planet would the time between sunrise and sunset be the shortest?
The time between sunrise and sunset would be shortest on planet Mercury. This is because Mercury has a very short rotation period, completing one rotation on its axis in just about 59 Earth days; resulting in a relatively short day and fast movement around the sun leading to quick sunrises and sunsets.
How does tidal locking affect the rotation of a moon?
Tidal locking occurs when a moon's rotation period matches its orbit around its planet, causing one side of the moon to always face the planet. This means that the moon's rotation is synchronized with its orbit, resulting in a fixed orientation of the same side facing the planet at all times.
Is there any planet which have same rotational and revolution periods as earth?
No. Mars has a similar rotational period but not revolution. For a planet to have the same revolution period as Earth would mean it would have to be in the same Orbit as Earth, with catastrophic results. One was in the same orbit as Earth during it's formation, it crashed into the Earth creating the Moon. It's possible that some extrasolar planet (that is, a planet of a star other than the Sun) might by coincidence have nearly the same rotational and/or revolution period, but we don't know of any yet (and it's not very likely that we ever will).
How many hours are in a day on a comet?
It all depends upon the rotation of the comet, as the length of a 'day' is determined by the rate of rotation and the position from which it is measured on the comet itself as well as the current position of the comet in relation to the nearest 'sun'. There is no simple answer.
Why do some planet have shorter days then earth?
The length of a planet's day is determined by the speed of it's rotation on it's axis. The faster the rotation, the shorter the day. The slower the rotation, the longer the day. This is affected by many factors such as any moons the planet may have (orbital speed, rotation speed or tide lock, distance and direction of travel of the moons all should be considered), past collisions with other large bodies (planetoids and other planets and their moons), and how the stellar dust and debris were moving and colliding when the planet was formed. Some planets are tide locked to their star and have no rotation and therefore no relative "day". One side faces forever toward the blazing heat of it's star, while the other side faces an eternal frozen night.
What is the relationship between a planets movement and a planets rotation and revolution?
Each year, the planet moves one full rotation around the sun, a movement. Each day, the planet revolves once, that's why in the day there is light because you are facing the sun, but when the earth revolves some more it is facing away from the sun eliminating the sun's light.
What is the difference in earth -sun relationship between revalution and rotation?
Some people like to distinguish between the two words, with revolution meaning rotation about the planet's own axis (e.g. in 24 hours), and rotation taking place around the Sun (in 365¼ days).
