Let's say we want to measure the distance between objects A and B. First, we measure the distance from the Earth(point E) to these objects(using Doppler-shifts).Then, we measure the angle AEB.We now know the lengths of two sides, and the angle between them. That's how we find the distance AB.
The gravitational attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.

The gravitational force between the two heavenly bodies will become 9 times more as the gravitation force between any two bodies in the universe is indirectly proportional to the square of distance between them.
Three units are commonly used in astronomy - the astronomical unit; the light-year; and the parsec.
asteroids
The mass of a heavenly body can be measured by knowing the orbital period (time it takes to complete one orbit around the other body), the distance between two bodies and gravitational constant. The orbital time is inversely proportionate to the square root of the sum of the masses of two bodies and directly proportion distance raised to power three by two.
The study of heavenly bodies is known as Astronomy.

gravitational force is exerted on heavenly bodies
stars are called heavenly bodies
