Do Distant Stars Have Gravity?

By looking at slight variations in the brightness of distant stars, scientists say they can determine their surface gravity, a technique that provides important clues to life-hosting properties of the planets that orbit them.

Do galaxies have gravity?

The galaxies are attracted to each other by gravity, but there is another repulsive force which cancels it, perhaps called 'dark energy' or 'the cosmological constant'. ... With no gradient in potential, there will be no force of gravity to act upon the galaxies.

At what distance does gravity end?

The Earth's gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!
