SUMMARY

The gravitational pull on an object decreases with the square of the distance, as established by Newton's law of universal gravitation. In a binary star system scenario, if star Y is 1 AU away from planet X and star Z is 1,000 AU away but has 10,000 times the mass, star Y will exert a greater gravitational pull on planet X. Specifically, increasing the distance to 10 times results in a 100-fold decrease in gravitational force. This relationship highlights the significant impact of distance on gravitational attraction.

How much does gravitational pull on an object decrease if the distance is increased 10 fold for example?

If planet x is stationary and part of a binary star system where star y is 1 AU away from it and star z is 1,000 AU's away, but also has 1,0000 times the mass, which star will exert more gravitational pull on planet x?

use the gravitation formula and notice that its inversely proportional to the square of the distance. so 10 fold increase means 100 fold decrease
