: How gravitation force for planets like Jupiter, Saturn, Neptune etc. is calculated? Is it accurate or rough estimate?
In: Physics
There is a thing called the gravitational constant that lets you calculate an objects gravitational pull.. which is directly proportional to the mass and inversely proportional to the distance between the bodies.. it’s expressed as F=G.m1.m2/r^2
So what you would need to calculate Jupiter’s gravitational pull on an object, would first be Jupiter’s mass (1.898×10^27kg) then the relative distance to whichever object you’d like to calculate it (say the sun and that’s roughly 7785000000000m) and then multiply both objects masses by the gravitational constant (6.67408×10^-11 N.m^2/km^2) and then divide it by the distance between the two objects multiplied by itself.
