pull of the sun on the Earth. This is based on the knowledge that ocean tides are caused mostly by the gravitational influence of the moon.

easy enough to do the math. in calculating gravity G is the same for both Sun and moon, as is mass of earth. so the variables are mass of sun vs moon and distance of sun vs moon. Which is greater in Mass / dist squared?

Sun
1.99x10^30 kg / (1.50 x10^11)^2 m (that is to surface, but radius is about 7x10^8, adding only a few thousandths, so negligible).
1.99 x10^30 / 2.25x10^22 = 8.4x10^7

Moon
7.35x10^22 / 3.63x10^8 (using perigee when gravity would be greatest)
7.35x10^22 / 1.32x10^17 = 5.56x10^5

Sun wins!

certain each little thing is certain by utilizing a a gravitational pull from each little thing. each little thing has a gravitational pull, Even human beings, yet were so small, you are able to also experience it. there's a focal element in our galaxy, a supermassive black hollow observed as Sagittarius A* interior the middle of our galaxy. adventure nonetheless each little thing in our galaxy revolves round the Supermassive black hollow, It money owed for decrease than 2% of the galaxy's mass. and also you're incorrect about loose floating asteroids. Asteroids also are certain by utilizing a gravitational rigidity. The asteroids in our image voltaic gadget are certain by utilizing the gravitational pull of our sunlight, it is why they orbit the sunlight, some asteroids get stuck by utilizing planets like Jupiter and Saturn and change into there moons. in spite of the actual incontrovertible truth that there might want to correctly be loose floating planets or asteroids interior the IGM (Inter Galactic Medium), the voids between galaxies. this is plausible that some area debris or planets ejected from there figure megastar and destroy out from there galaxy, only floating round in darkish voids. yet finally even this stuff receives stuck by utilizing yet another gravitational rigidity, they could finally run into yet another galaxy or a stellar black hollow.
