Kepler was the one who during the Renaissance, came up with the theory of elliptical planetary orbits around the sun. Up to that time the planetary orbits were assumed to be circular. By using the observations and data of Tycho Brahe, and also using both mathematical and physical (relative to the properties of matter) proofs, he thus used the scientific method to determine the type of orbits. In other words, he used the model that Brahe had worked out and then developed that model into an accurate appraisal of the orbits. This is the scientific method, starting with what is known and doing investigation into what is unknown by studying the material world and basing one's expanded thinking on the new facts unearthed in the process. In the modern world we all use this method, from figuring out why a vacuum cleaner is not functioning to the theory of plate tectonics.

Answer:

People firstly believe that the planets move in a circular orbit until Newton came up with his hypothesis by inventing calculus so that we could understood and calculated planetary orbits and their accuracy.

Explanation:

Everyone assumed the planets were perfect circles until Newton came up with an idea. Slowly people would make maps of the orbits that added circles on circles, and they could never really explain about the movement of the planet. They simply say that planets move on circles but they lacked the math to explain or prove it. Then Newton came up with an idea of inventing calculus so that we could understood and calculated planetary orbits and their accuracy.

Firstly people used their observations and say that the orbits looked like circles, then they developed their models and did the math, and proposed their hypothesizes which were wrong, until Newton came along and tried to match a model that used elliptical orbits and invented the math that allowed him to make predictions with it. His model worked for most planets.

However he could not explain about the planet Mercury for instance since it was a very strange orbit. Then after the Einstein's theory of General Relativity he could also explain very deeply about it.

Scientists and Astronomers made hypothesizes that there was another planet orbiting too close to the sun to see with telescopes, called Vulcan, that explained mercury's orbit before Einstein's theory. Then long after we had telescopes which was good enough to see if there was a planet orbiting closer to the sun than mercury.
