Newton's great discovery - gravitational force revealed that everything in the world is affected by the gravitational pull of all other things, and the strength of the force depends on the mass and distance of the two objects. This law of nature was developed by the 17th-century English scientist Isaac Newton. He revealed the law of gravitation and unveiled the mystery of the operation and interaction of all things in the universe. Regardless of the size of the object, its proximity or not, the gravitational force is constant during this period.
This law not only constructs Newton's mechanics system, but also contributes to the interpretation of the laws of planetary motion and the foundation of cosmology. Gravitational force, the powerful force contained in the mass and distance of objects, is known as the greatest attraction in the universe.
The gravitational constant (g), although small, plays an indispensable role in the evolution of the universe. For example, parameters such as the path of planets, the rate of star formation, and the rate of expansion of the universe can be used.
In the field of astronomy, the law of gravitation is widely used to analyze the trajectory of celestial bodies. It can not only explain the rotation of planets around the sun and the orbit of satellites around the earth, but also reveal the laws of celestial motion in the galaxy. As we explore the mysteries of the universe, we discover that there are many fundamental physics principles involved. At the beginning of the universe, primordial matter gathered to form planets, and in this process, gravity played a decisive role, guiding all the planets to revolve around the sun.
However, in addition to gravity, there is also a wonderful interaction – the Lagrangian point. If the two objects are balanced at these two points, they will remain stable and not deviate from their orbits in the long run. This interaction has allowed the planets to move in a specific plane for thousands of years.
There is another key element to consider for the deeper reason – angular momentum. Angular momentum describes how an object moves, and its behavior is similar to the mass and velocity of an object. When the planets revolve around the Sun, they also rotate around their axis. This rotational interaction creates angular momentum that allows the planet to resist the gravitational pull of other celestial bodies and maintain its stability in orbit. However, different planets have different angular momentum, which is why they can stabilize themselves in different planes of motion. Complex interactions formed our solar system today.

Astronomers have observed the trajectory of star S0-2 and have been able to estimate the mass of the galactic black hole with an error of only 10%. This has important implications for our understanding of the nature of the universe.
