How far does gravity reach?

Question

please help

Answer 1

Infinit,  Strength decreases according to the inverse square law.  But it's effect is always there.

Answer 2

Universal law of gravitation

Force of gravity = G*(mass1+ mass2)/(radius)^2

G is the constant G=6.7X10^-11Nm^2/kg^2

So the force of gravity is inversly proportional to the radius squared. So the farther away you go you get less attraction between the two masses. It might be very small but the forces of gravity applies to very distant objests. It is just not of any great amount.

Answer 3

Theoretically the gravitation attraction between any two bodies with mass has an infinite spatial reach, but its strength diminishes so  rapidly over distance between the centers of mass of those objects that for all but the heaviest objects (e.g. stars and planets) , it is effectively zero at measurable distances.  

Answer 4

no limit, it reaches forever.
