What physical law states: When an object nears a massive celestial object in space, it is attracted to its gravity

There is always some gravitational force between masses. The amount of the force is inversely proportional to the square of the separation distance, and proportional to the product of the masses.
Neither particle has to be "massive" or "giant" and they do not have to be "near" for the gravitational attraction force to exist.
The physical law that describes the attraction between objects is called Newton's Law of Universal Gravitation. This fundamental law was formulated by Sir Isaac Newton in the 17th century and is still widely used today.
To understand Newton's Law of Universal Gravitation, we need to know two important variables: the mass of the objects involved and the distance between them. The law states that every object with mass exerts a gravitational force on every other object with mass. The force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers.
Mathematically, Newton's Law of Universal Gravitation can be expressed as:
F = G * (m1 * m2) / r^2
Where:
- F is the gravitational force between the two objects
- G is the gravitational constant (a constant value, approximately 6.67430 × 10^(-11) N m^2 / kg^2)
- m1 and m2 are the masses of the two objects
- r is the distance between the centers of the two objects
In the context of celestial objects in space, such as planets, stars, or moons, the massive object (e.g., a planet) exerts a gravitational force on any nearby object or satellite (e.g., a spacecraft), causing it to be attracted towards the massive object. This law explains why objects like planets orbit around the sun or why the moon orbits around the Earth, as they are constantly being pulled by the force of gravity from the massive celestial object.
