Answer:
The gravitational constant is the proportionality constant that is used in the Newton's Law of Gravitation. The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm2/kg2.
In physics, the value of capital G (gravitational constant) was initially proposed by Newton.
G = 6.67408 × 10-11 N m2 Kg-2
The value of gravitational constant on the moon or on mars or at any part of the universe remains unchanged making it an invariant entity.
