Gravity doesn't "only happen on Earth" - Gravity happens all over the whole universe. Gravity is what keeps all the planets orbiting the Sun - and it is what keeps our solar system obriting within the Milky Way galaxy, and that whole galaxy is itself subjected to the gravitational pull of all other bodies in the universe. Every body - be it a star or a pea - exerts a gravitational force on every other body in the universe. Gravity is a property of matter - everything has it. Gravity is weaker in some places - such as on the Moon where it is one-sixth as powerful as on Earth, but that is due to the composition of the Moon.

∙ 14y agoIt's not. All planets, stars, moons, and everything else has gravity. Also, many of the planets have an atmosphere, but their air isn't the same as the air here. For example, the air on Venus has much more sulfur and carbon dioxide than the air here, so we couldn't breathe it safely. And the air on Jupiter is mostly Hydrogen.

or
The gravitational pull of the moon keeps us on the earth surface so we arent floating around althought that would be cool the moon pulls in the tides at night.
2nd Answer:
May I try to answer your question using physics? I promise there is no pain. (g)
1. Every object with mass (on Earth, we call it weight) also has gravitational attraction.
2. When scientists calculate the pull of gravity, they always assume that the gravitation goes clear to the center of each object that they're studying.
3. So, if you are in your normal location, the pull between you and earth can be easily calculated. But what if you were on top of the highest mountain in the world? The distance from the center of the Earth to the center of you would be longer, and so the gravitational pull between you and the Earth would be very slightly less. In fact, if you could fly out into space, the Earth and you would attract each other even less.
4. If you could stand on the surface of the Moon (or Mars, or Venus, or . . .) you would find you and the Moon (or Mars, or Venus, or . . . ) attracting each other . . . but the Earth and you would still pull on each other, just very much less than when you were at home.
5. Is gravity just on the surface? Well, think of the miners who work a mile or two underground, or boats that sink in the ocean, sometimes many miles . . . in both cases, the pull of gravity still pulls the people (or boats) toward the center of each other, or at least until they hit something solid.
6. Believe it or not, but you and, say, your best friend have the pull of gravity between each other. Gravity is the weakest natural 'force', so you don't feel the pull between you and your friend - it is too weak to feel. But get close to a huge object, oh, say, like the Earth, and you find that the huge object has a very noticable pull simply because it is so huge.
7. If you stood on one of the really huge planets, like Jupiter, say ( you can't because there is no solid ground, but still . . . ) There would be such a large pull of gravity between Jupiter and you that you would not be able to stand up, no matter how hard you tried.
The Moon and Earth have a gravitational pull on each other that:
a. Keeps the Moon orbiting around Earth, not flying out into space, and
b. Creates tides in each other's surfaces, including dirt, rocks, mountains, valleys, and oceans. A 'tide' is really a ripple or narrow bulge that the Moon drags along the surface of the Earth as the Moon orbits around the Earth. Land is too stiff to really notice that it is bulging, but water moves easily and bulges quite a bit. This cause swhat we call the 'ocean tides'. The Sun and Earth pull on each other, too, and the Sun causes smaller tides. That is why we have so many different tides in addition to "High tide" and "Low tide".

Do you only have gravity on earth?
No. All planets, moons, and stars have gravity. Techincally, anything with mass has gravity, but it is only noticeable with very large objects.
Why does the moon not crash on earth but stay in space and not float away or into earth?
The moon and other planets and their satellites are held in space by the force of gravity from other planets and satellites. If the moon tried to drift off into space, gravitational forces from the Earth will keep it from floating away. It doesn't crash into the Earth because planets and moons pull AGAINST each other and keep each other from drifting away.* * * * *Only partly true.The moon does not float away because of the action of earth's gravity - whether you view this as a force or a distirtion of space-time in the moon's path.The moon does not crash into the earth, not because of other planets or satellites, but because of the momentum of its orbit around the earth.
Is there gravity on other planets in the solar system?
Yes there is gravity on other planets. In fact, there is gravity on object that has mass. That gravity is just really small for objects with little mass. We only see gravity like we experience on Earth when the mass becomes really large. If you require proof that those other planets have a gravitational pull you need only remember that NASA has sent multiple space probes to other planet and put them into orbit around that planet. An impossible feat for an object what has no gravity.
Would newtons change on the moon?
No. Newtons are a measurement of mass and are relative only to Earth's gravity and are not affected by changes in gravity. Only weight is affected by changing gravity. On Earth, weight and mass are the same because Earth's gravity is the benchmark constant for measuring mass in Newtons, and weight is affected by that very same factor (Earth's gravity). On other planets, mass is unchanged because the Earthly gravity is a constant (and therefore, unchanged), and the weight changes because now it is affected by a new planetary gravity.
How is the earth similar to other planets?
well the Earth is not exactly the same to other planets actually, it is the same because they're all parts of the solar system and they pretty much spin in the same direction but their features/characteristics are not much similar. Neither it is in size nor in appearance sooo....Hope this helps !!
Why is there only gravity on earth and not any other planet?
All planets have gravity, not just Earth.
Why is earth the only with life?
It has different gravity and climate than other planets.
What will happen to the earth's gravity if there was no other planets?
The earth would only rotate the sun because the sun is a star so only stars and meteors would be left.
Do you only have gravity on earth?
No. All planets, moons, and stars have gravity. Techincally, anything with mass has gravity, but it is only noticeable with very large objects.
Does earth's magnetic field only affect other planets?
No. Earth's magnetic field only affects earth, not other planets.
What would happen if only gravity were operating earth?
Well, everything would be stable gravitationally, but if there were no other forces, like electromagnetism for instance, then our atoms might not hold together, or they would get mixed into the atoms where we sit or walk, etc. We need other forces.
Is earth the only planet with gravity?
yes and no, planet earth is the only earth with gravity because there is only one earth, however planet earth is not the only planet with gravity or even the only object with gravity. every single planet and every star and even every comet or asteroid has gravity but its not just objects in space; everything is made of matter and all matter attracts other matter which is what causes gravity so the chair your sitting on, the computer in front of you, and even you have a small amount of gravity.
How does weight differ depending on gravity?
Weight, mathematically speaking, is just mass times acceleration due to gravity. Mass is inherent in the object being weighed, and does not change. However, gravity can change (albeit very slightly) even on different points on the earth's surface. And comparing the earth's surface to that of other planets, gravity changes radically due to the difference between Earth's mass and that of other planets. So the greater gravity is, the greater the weight of a particular object will be. This explains the difference between weights of an object on the earth versus that on other planets -gravity is different on different planets. It also explains why comparing the weights of two objects at the same point on the earth's surface shows the difference in the mass of the two objects: the acceleration due to gravity is the same, so that masses are the only things that change.
What planet has the most gravity beside earth?
Jupiter and Neptune are the only planets in our Solar System that have more gravity than the Earth. Jupiter's gravity is about 236% that of the Earth, and Neptune's gravity is about 112% that of the Earth. Edit: Because of uncertainties and different definitions you can get data that says Saturn and/or Uranus also have slightly stronger gravity than Earth's.
Why life is possible only in earth not in other planets?
Because Earth is the only place where we can murder the English language and ask questions like, "Why life is possible only in earth not in other planets?"
