Its falling and falling every years.
If there was no gravity, the Sun and and the planets would never have formed.
If th sun's gravity were to disappear, Earth would go off in a straight line into interstellar space.
It would get bigger
If it did, it would be destroyed. Due to gravity, it would not happen.
The planets will get too hot than melt/explode.
The Sun doesn't have enough mass, and therefore, not enough gravity, for this to happen.
The sun's gravity would pull the earth in to it and the earth would burn up
The sun gravity is stronger
it would push it away
The sun doesn't have to do anything special for this to happen; the sun is at the center by definition, Its intense gravity keeps the planets and other orbiting materials in their orbits.
Anything with mass has gravity. The sun's mass is enormous. Therefore the sun has strong gravity.
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
