Newton did not discover gravity. He realized that the same force, gravitational force, that acts on all things here on earth go thru space and act on the moon to keep it in orbit. The same for the planets revolving around the sun.
Parmenides discovered that the earth was round by the earth's shadow
it doesn't.
Eratosthenes
Probably newton...Since force is newton.& if its not "newton" then its momentum.
No
gravity
Isaac Newton was both an inventor and a discover. Newton invented the first practical reflecting telescope and the laws of motion and universal gravitation. With the help of others, he discovered the true shape of the earth.
Newton discovered how the world was held together when the memorable event of the apple falling on his head helped him discover the force of gravity. He then concluded that gravity pulls together all the particles of Earth, therefore holding it together.
Galileo. He did a lot, but it was a combination of several people who all contributed. In particular I would say Kepler and Isaac newton were important.
Galileo. It's more complicated than that. Several people were involved. The main ones were Copernicus, Kepler, Galileo, and Newton.

On earth, one newton is 0.1kg
If you mean the weight of the entire planet Earth, the question is, "weight on what". Gravitation is always a force between two objects. For example, if you have a mass of 60 kg., then you weigh about 600 Newton. This is the force with which Earth attracts you. By Newton's Third Law, you will attract planet Earth with the same force: 600 Newton. So, in this example, the "weight of Earth" (against you) is 600 Newton. The force with which Earth attracts, and is attracted by, other objects, will vary, depending on the mass of the other object, and the distance.If you mean the weight of the entire planet Earth, the question is, "weight on what".

Sir Isaac Newton discovered Earth's gravitational pull and made many other discoveries, which later led to him creating the three laws of motion. Many years ago, Galileo invented the telescope to observe Jupiter and it's four moons. Fifty years after that, Newton used a new and improved telescope to observe other objects in space.
The earth has many scientific things to discover!
