Do All Planets Rotate In The Same Direction? And Other... - USVAO.
The gas giants, the four planets farthest from the Sun, do spin faster than the inner planets. However, rotational speed has almost nothing to do with the distance a planet is from the sun. Having. Answer 1 of 4: This #x27;revolving#x27; around the Sun is known as #x27;orbiting#x27;. Orbits are the result of a perfect balance between the forward motion of a body in space and the pull of gravity on it from another larger body in space. An object with a given mass goes forward and tends to keep going forwa. The net effect is a gradual braking of the moon#x27;s rotation, until it is stuck with the bulge always pointing right at the planet. This process is faster the smaller the moon is relative to its planet. 2 level 1 praesartus 7 yr. ago They have moons because gravity keeps them there.

A star forms when a molecular cloud collapses under its own gravity forming a dense core sustained by nuclear fusion. This happens only when the force of gravity pulling in exceeds the outward push of pressure. High-density molecular clouds have stronger forces of gravity pushing in, making it easier to overcome the total pressure within the cloud. Credit: SDSS. What they found was that these galaxies spin much more rapidly than the Milky Way, with the largest spinning at a rate of up to 570 km/s 350 mps - almost three times as fast. As mentioned by one or two above, gravity is a perceived effect caused by curving space. Mass causes this curve, so mass causes gravity. Electro-magnetism has nothing at all to do with gravity, and the spin of the earth actually slightly reduces our perception of gravity since the spin is pushing us AWAY from the surface.
What if the speed of Earth#x27;s rotation suddenly got faster?.
However, dwarf planets do not have sufficient gravity to attract or push away smaller bodies in order to clear their orbit and therefore, do not fit the definition of a planet according to the IAU. The term dwarf planet, coined by Stern, was adopted by the IAU in 2006 as a category of sub-planetary objects. No, the Earth has gravity just because it has mass. It would have almost exactly the same gravity even if it wasn#x27;t spinning at all.
Re: Why do the Jovian planets rotate faster on their axis than... - MadSci.
Closer planets revolve faster, more distant planets revolve slower. Why? The answer lies in how gravity works. The force of gravity is a measure of the pull between two bodies. This force depends on a few things. First, it depends on the mass of the sun and on the mass of the planet you are considering. The heavier the planet, the stronger the. Apr 14, 2003 In our solar system, the giant gas planets Jupiter, Saturn, Uranus, and Neptune spin more rapidly on their axes than the inner planets do and possess most of the system#39;s angular momentum. The. Below is a list of the gravitational pulls of each planet from strongest to weakest. 1. Jupiter has an incredible gravitational pull of 24.79 m/s2. This is nearly 2.53 times the gravity of what we experience here on planet Earth. If you weighed 100 lbs on Earth you would weigh 236.4 lbs on Jupiter. 2.
Which Planet Rotates The Fastest And Slowest.
The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about 7.5 billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. It#x27;s much easy to make things spin than it is actually to have things stationary. So as the planet system forms, the disk spins faster and faster to lose angular momentum. The material can then form and fall towards the star, and out of this collapsing disk you get these sort of lumps and bits and pieces, which become planets. These planets are. The speed of a planet#x27;s rotation depends on a few different factors. One is the distance from the sun. The closer a planet is to the sun, the faster it will rotate. This is because the sun#x27;s gravity is stronger on planets that are closer to it. Another factor is the size of the planet. The larger the planet, the slower it will rotate.
Why do the outer gas giant planets rotate faster than the inner... - Quora.
The faster a planet spins, the more its rotation causes it to bulge outward at the equator. That#x27;s because as a planet rotates, there#x27;s a tug-of-war between the way material wants to fly off the. Planets are round because a gravitational field surrounds them. This means that the earth#x27;s gravitational force pulls and merges the planet#x27;s mass into a sphere. The surface pulls back upon the planet#x27;s center, creating a bulge in the middle of the planet. This gravitational pull is what makes planets round. This pull is strongest at a.
What determines the rate at which a planet spins?.
This results in a limit for how fast an object can rotate and still keep itself together. If it rotates too fast, the outward acceleration felt by the elements in the body may be more than the force that keeps them bonded together, and if this happens, the body breaks up. Other than this, there is no real law concerning rotations.
Why do all of the planets rotate on their own axes? - Quora.
Now, in a new study, scientists from NASA#x27;s Goddard Space Flight Center in Greenbelt, Maryland have found evidence that Mercury#x27;s inner core is indeed solid and that it is very nearly the same size as Earth#x27;s inner core. Some scientists compare Mercury to a cannonball because its metal core fills nearly 85 percent of the volume of the planet. As it condensed out of the disk, each planet began to spin faster; the more mass the planet had, the more angular momentum it had, and hence the faster it would spin. This takes place even though the Jovian planets are physically bigger than the terrestrial planets - the key is that they have relatively more mass than radius..
Why do the gas giant planets have so much gravity when they do not have.
If the same earth were spinning 10,000 times faster, would be 0.727 rad/s, and upwards accelleration at the equator due to the spin would be 3.4 Mm/s 2. Obviously this is much more than the downward accelleration due to gravity, so this system wouldn#x27;t be stable and the ridiculous factor of 10,000x higher spin speed makes no sense. This 1996 song compares love and attraction to planets, stars, and gravity. The analogy is almost poetic. And in that moment, I was hit with the realization that this delicate layer of atmosphere is all that protects every living thing on Earth from perishing in the harshness of space..
Do planets near the sun spin faster or slower than planets... - Answers.
Sometimes planets move or migrate towards their host star. As the planet gets closer to the star, its atmosphere heats up, causing the atoms and molecules to move very fast and escape the planet#x27;s. The full force of gravity is offset to a small amount by the centrifugal force. Or, more precisely, some of the gravity is used as a centripetal force to keep us rotating with the Earth. This, however, does not affect objects in orbit. The moon#x27;s orbit is essentially unaffected by the Earth#x27;s spin. Mar 29, 2017 #4 eiyaz 41 0. Planet with the slowest rotation: Venus. Venus is the second planet from the Sun, circling it each 224.7 Earth days. It has the longest rotation time frame 243 days of any planet in the Solar System and turns the other way to most other planets which means the Sun ascends in the west and sets in the east. It doesn#x27;t have any satellites.
How fast is Earth moving? | Space.
The vessel would also need to be constantly accelerating and at a constant speed to maintain the gravitational effect, and thus would not have gravity while stationary, and could experience significant swings in g -forces if the vessel were to accelerate above or below 1 g. That#x27;s because of the extra centrifugal force that#x27;s generated as the equator spins faster combats gravity. Press fast-forward on that, and your weight would drop even further. Odenwald calculates. Answer 1 of 9: Newton#x27;s Law of universal gravitation and Kepler#x27;s Law of planetary motion describes the movement of planets around the sun. Equations are derived from these laws and hence the birth of Celestial Mechanics. But nowhere in the literature can we find an accepted law of Planetary Ro.
ELI5: Why do planets have moons and how to they get there? - reddit.
Select TWO answers. O a. Terrestrial planets spin faster, so more gases get flung into space b. Terrestrial planets are colder, so they trap less gas c. Terrestrial planets have weaker gravity, so they can#x27;t hold onto thicker atmospheres O d. Jovian planets have more. All planets except for Pluto, the runt seem to orbit pretty much in the same plane the plane of the ecliptic is a convenient reference plane for the others, in the same direction counter-clockwise when seen from north, and the planets usually spin in the same sense, as does the Sun. Astronomers see that as evidence that all these objects. If it were just the gravity of something pulling it towards the middle, a galaxy would rotate like the solar system--fast motion near the middle, slower and slower as one gets away. Vera Rubin has examined the light of galaxies and has determined by the Doppler effect that many of them, apart perhaps for the outer edges, rotate together, like.

Answer: Yes. The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun#x27;s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun#x27;s gravitational pull is weaker, so the planet moves slower in its orbit. -- Jeff Mangum.. The only effect a fast spin rate has on a planet#x27;s gravity is the centrifugal force at the equator can create a counter-force to the planet#x27;s gravity, and unless the spin was incredibly rapid the effect is minimal at the equator reducing to nothing at the poles. So by increasing the radius of a planet with Continue Reading Simon Bridge.
Why Are Planets Round? - Johnny Holland.
The inner planets Mercury, Venus, Earth, and Mars are small, rocky planets with a higher percentage of heavy elements than the outer planets. They have less gravity due to their smaller mass, and. As the cloud collapses, the averagedirection of motion of the cloud is kept and as gravity pullseverything closer to the center, the conservation of angular momentumcauses that average motion to speed up. You can do this experiment athome if you have a chair that spins.
