Nothing, an object's mass stays the same regardless of what gravitational forces act upon it, assuming the object stays in one piece.
If the force of gravity on Earth suddenly grew stronger, your weight would increase because weight is a measure of the force of gravity acting on your mass. Your body would feel heavier and you would find it more difficult to move around.

The EARTH
The gravity of Earth is approximately six times stronger than that of the Moon.

Earth
Stronger gravity than what? The gravity of Venus is stronger than that of the moon or of Mars, but weaker than that of Earth.
stronger
It is stronger.
The gravitational field strength (how strong gravity is) on the Earth is 6 times stronger than on the moon.
The same thing that happens every night when the sun disappears...nothing! Gravity on Earth is not dependent on the Sun. But life on Earth is, gravity would be the least of Earth's problems if the Sun dissapeared
Mercury has weaker gravity compared to Earth. Its surface gravity is about 38% of Earth's gravity.
