text: what is the gravity of the sun? does the sun have gravlty, if so how much gravity does the sun have gravity,  f=gmm/r^2,  where g is a the gravitational constant, m is the mass of the sun, m is the mass of the earth and r is 1au (the distance between the earth and the sun)  f=6.673e-11(1.98822e30)(5.9742... =3.541722227e22 n  that is the forces of the sun that is keeping us in orbit. however, the surface gravity is  f=gm/r^2 = (6.6733e-11)(1.98822e30)/(6955... = 274.28 ms/s or 27.96859298g  where g is the gravity on earth
