The planets would no longer follow their orbital paths around the Sun.
They would move away from the Sun and travel in straight lines.
The object would crash into the planet.
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
The object would crash into the planet.
If there was suddenly no gravity, the planets would continue to move at the same speed in the current direction they are facing in a straight line until a collision occurs. By the way, if gravity suddenly stopped, the laws of physics would suddenly, drastically change, because gravity is one of the four fundamental interactions.
Gravity keeps planets in orbit around the sun. If planets were not subject to the gravitational attraction of the sun, they would fly off into interstellar space. In addition, gravity is also what holds planets together. If there were no gravity, the planets, and the sun, would disintegrate under the force of their own spin. There would be nothing left of the solar system but an expanding cloud of gas and dust.
If there was no gravity, the Sun and and the planets would never have formed.
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.
The object would crash into the planet.
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.
They would fly randomly through space.
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
The object would crash into the planet.
The planets would fly off into space and lose their moons and atmospheres. The sun would explode from its enormous interior pressure.
Without the Sun's gravity and heat they would all go off in straight lines and freeze up solid.
Yes, gravity affects your weight on different planets. Weight is a measure of the gravitational force acting on an object, so on planets with stronger gravity, you would weigh more, and on planets with weaker gravity, you would weigh less compared to your weight on Earth.
There would be no life because with out the planets and the sun pulling on each other they would spin out of control and possibly crash into each other.
The earth would only rotate the sun because the sun is a star so only stars and meteors would be left.
