If two celestial bodies have the same mass but are placed a distance apart what would increase the gravitational force between the two bodies

There are a few factors that could increase the gravitational force between two celestial bodies of the same mass and distance apart.

1. Increasing the mass of one or both of the bodies: The gravitational force between two objects is directly proportional to the product of their masses. Therefore, increasing the mass of one or both celestial bodies would increase the gravitational force between them.

2. Decreasing the distance between the bodies: The gravitational force between two objects is inversely proportional to the square of the distance between them. Therefore, decreasing the distance between the two celestial bodies would increase the gravitational force between them.

3. Changing the medium between the bodies: If there is a medium between the two bodies, such as a planet's atmosphere or ocean, changing the density or composition of that medium could affect the gravitational force between the bodies.

Overall, increasing mass or decreasing distance are the most effective ways to increase the gravitational force between two celestial bodies.
