If there was no gravity, the Sun and and the planets would never have formed.

What would happen to our solar system if there were no gravity?
The planets would fly off into space and lose their moons and atmospheres. The sun would explode from its enormous interior pressure.
Why are there no moons around moons?
Most moons orbit close enough to their planets that the planet's gravity would render any orbit around a moon unstable in the long term.
Is a planet with many moons an inner or outer planet?
In our own solar system, the only planets with many moons are outer planets. It seems likely that if there were a large planet close to a companion star, the star's gravity would strip away any orbiting moons. However, we have no way of detecting the moons of any extrasoloar planets.
What will happen if planets got out of their orbits?
Planets can't really get out of their orbits because of gravity; if gravity somehow stopped having an effect, the planets would continue in a straight inertial line with inertia from the point at which gravity stopped.
Why do inner planets have less moons then outer planets?
Because when they are close to the sun first of all they are are smaller so if they had a moon the moon would have to be kinda small. And also the planets close to the sun are made to be able to get to high temperatures. Earth can't get satellites to Mercury and a moon is related to the satellites and the moon would burn up in the heat. All mass has gravity. The inner planets cannot "hang on" to their moons due to their lack of mass, therefore they are unable to overcome the suns gravitational affect on the moons which would pull them into the sun. The outer planets can "hang on" to their moons and attract more because of their mass (therefore gravity). The distance from the sun has less of an impact on these moons, therefore, the sun cannot pull any of the moons away from the outer planets. Also, the outer planets are "kind of" moon magnets due to their gravitational pull.
What would happen if there was not enough gravity to keep the planets in orbit round the sun?
Planets would most likely drift until they were attracted to the next largest center of gravity, say Jupiter. But without a centre of gravity, the planets would have nothing to hold themselves in a fixed point and would simply drift.
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
Would you fall off of Uranus?
No, like all planets (and most moons), uranus has enough gravity to prevent things from flying off into space.
Which planets do you think would have great extremes of temperature on the different sides?
This will happen on planets which have no atmosphere, or no significant atmosphere - especially Mercury, Mars, as well as planetoids or moons.
What will happen to the moon and planets if gravity did not exist on the solar system?
They would fly randomly through space.
Why is earth's gravity so important to life on earth?
Basically, If the sun had no gravity we would be drifting off into space and we wouldn't orbit anything. but Because the sun has gravity it pulls the planets in, allowing them to orbit the sun. Without the gravity of the sun there would be nothing to stop us from flying out into the cold darkness of space. As a matter of fact without the force of gravity there would be nothing if that could exist but an infinitesimally fine misty characterless soup that would never bind together. Whose solar system?
What is a measurement that astronomers would make in kilometers?
Diameters of planets, planetoids, or moons are often expressed in kilometers.Diameters of planets, planetoids, or moons are often expressed in kilometers.Diameters of planets, planetoids, or moons are often expressed in kilometers.Diameters of planets, planetoids, or moons are often expressed in kilometers.
