Could there be a planet bigger than Earth, but with less.

Things would get more catastrophic the faster we spin. Losing gravity and weight Centrifugal force from the Earth’s spin is constantly trying to fling you off the planet, sort of like a kid on. 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's orbit is essentially unaffected by the Earth's spin. Mar 29, 2017 #4 eiyaz 41 0..

Obviously this is much more than the downward accelleration due to gravity, so this system wouldn't be stable and the ridiculous factor of 10,000x higher spin speed makes no sense. What if the earth was only spinning 10x faster? Then ω would be 727 x 10-6 rad/s, and the centrifugal accelleration at the equator 3.4 m/s 2. That's a significant fraction of the. Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. Just as the Moon orbits the Earth because of the pull of Earth's gravity, the Earth orbits the Sun because of the pull of the Sun's gravity. Why, then, does it travel in an elliptical orbit around the Sun. Answer (1 of 2): Perhaps surprisingly, yes. Earth spins on its axis once every 24 hours (the definition of a day). Mars, which is smaller, spins slightly slower with a period of 1 day and 37 minutes.

Does the inner planets have more or less gravity... - Answers.

In 2020 scientists recorded the 28 shortest days since 1960. Last year that trend did not continue, with the shortest day in 2021 being longer than. Along the equator of a planet, a circle half way between the north and south poles, gravity is holding the edges in but, as it spins, stuff wants to spin out like mud flying off a tire. Saturn and Jupiter are really big and spinning really fast but gravity still manages to hold them together. That's why they bulge in the middle.

Q & A: Why do Planets have Gravity - Department of Physics.

Because of this, Mars has 0.38 times the gravity of Earth, which works out to 3.711 m/s 2. Gravity on Jupiter: Jupiter is the largest and most massive planet in. If you draw a big circle in a huge peice of paper, and train an ant to follow the line you draw. Because of perspective, the ant will think it's walking in a straight line, but will actually end up back where it started. Similarly, the earth is a globe. If I get in an aeroplane and go south in a straight line for long enough I will end up back.

Gravitational Pull of the Planets - Planet Facts.

Do planets near the sun spin faster or slower than planets... - Answers.

Planet Jupiter - The Most Massive Planet. Jupiter is the biggest planet in our solar system, and so it also has the strongest gravitational field among all the planets. The only celestial object whose gravitational pull exceeds that of Jupiter is the Sun. Jupiter is roughly 318 times the mass of Earth, yet its surface gravity is not 318 times.

Orbital Speed of Planets in Order - Planet Facts.

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's angular momentum. The. At first, special relativity may not seem to have much to do with gravity, but it was an essential stepping stone for Einstein for understanding gravity. Moving clocks tick more slowly. Experiments during Einstein’s time had shown that the speed of light appeared to be constant. No matter how fast you try and catch up, light always appears to. The closer a planet is to the sun, the faster it will rotate. This is because the sun’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. This is because it takes more time for the larger planet to complete one full rotation.

1. Sure, if the earth were spinning much faster then its gravity would not be strong enough to keep things on the surface from flying off. In a realistic case, stuff spinning that fast would never have managed to lump together as a planet to begin with. Let's say, however, that as in your question it had lumped together and then been set spinning. Answer (1 of 4): “Can planets with way more gravity than Earth reduce their gravity by spinning really fast?” The Earth itself is an example of why the answer is “Yes.”. The only effect a fast spin rate has on a planet's gravity is the centrifugal force at the equator can create a counter-force to the planet'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.

Which Planet In Our Solar System Has The Most Gravity?.

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't hold onto thicker atmospheres O d. Jovian planets have more. Planets structure from material in this circle, through growth of littler particles. In our nearby planetary group, the mammoth gas planets (Jupiter, Saturn, Uranus, and Neptune) turn more quickly on their axes than the inward planets do and have a large portion of the framework’s angular momentum.

Mercury’s Spin and Gravity Reveals the Planet’s Inner Core.

Bigger planets don't always have greater masses. Remember, mass and volume are related by M = ρ 4 3 π R 3 where ρ is density. Make ρ small enough and the gravity and be as weak as you like. So the answer to the title question is a firm "yes.". The researchers looked, most importantly, at the planet’s spin and gravity. The MESSENGER spacecraft entered orbit around Mercury in March 2011, and spent four years observing this nearest planet to our Sun until it was deliberately brought down to the planet’s surface in April 2015. Centrifugal acceleration is ω 2 r, so in order to have a centrifugal acceleration of 1 / 2 g at the equator you will need ω = g / 2 r, giving ω = 0.000875 rad/s; the planet rotates about 12 times faster than Earth, completing a rotation in just a little under 2 hours. ( ω is the angular speed in rad/s, r is the radius of the planet, here.

Does spin affect gravity on a planet? - Quora.

Now, in a new study, scientists from NASA’s Goddard Space Flight Center in Greenbelt, Maryland have found evidence that Mercury’s inner core is indeed solid and that it is very nearly the same size as Earth’s inner core. Some scientists compare Mercury to a cannonball because its metal core fills nearly 85 percent of the volume of the planet. This is because of the gravitational force being exerted on the planets by the sun. Additionally, according to Kepler’s laws of planetary motion, the flight path of every planet is in the shape of an ellipse. Below is a list of the planet’s orbital speeds in order from fastest to slowest. 1. Mercury. 2. Venus. 3. Earth. 4. Mars. 5. Jupiter. 6. Saturn. 7. Uranus. 8. Answer (1 of 5): Spinning of the earth (or a planet) does not affect the gravity, but spinning of a planet reduces the gravitational pull experienced by an object placed on the surface of that planet. However, the effect of spinning is most on equator and least at.

How would gravity change on a planet rotating around.

Artwork: Before people understood gravity, they had to devise ingenious explanations for why the planets moved. In this 14th-century illuminated manuscript, angels make the planets rotate by cranking giant handles! For more about the development of these ideas, see the fascinating Wikipedia article Dynamics of the celestial spheres. Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Planets originate as dust particles that are attracted to each other mainly by static electricity. Once all those accumulated particles build up enough mass, then gravity will attract other masses.

Can a planet be bigger than Earth but still have a habitable gravity if.

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. 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.
