Any theory which involves things orbiting round a central object. Such as the early theory of atomic structure.
Isaac newton discovered the three principles of planetary motion
No. Kepler discovered the laws using Tycho Brahe's data.
William Kenneth Hartmann is a prominent planetary scientist known for his research on the formation and evolution of celestial bodies, particularly the Moon and Mars. His work has significantly advanced our understanding of impact processes, planetary geology, and the history of water on Mars. Hartmann's contributions have also influenced theories related to the origin of the Moon and the dynamics of planetary systems, making him a key figure in the field of planetary science and astrobiology. His research continues to inform current missions and studies related to planetary exploration.
It is a scientific theory
Kepler used observation data by Brahe to find how planets moved. This is "A posteriori" reasoning (finding the theory after the facts were obtained). Newton used his theories of motion and gravitation to explain the orbital motions. This is "A priori" reasoning (having a theory and using it to explain facts). Kepler was a mystic as well as a scientist, and so was Newton. But they attacked the same problem from two different directions. Kepler searched for and found mathematical relationships inside the data. Newton used mathematical relationships he already had to verify the data's accuracy.

It appeared from flattened disk of gas and/or dust orbiting the sun.
Tycho Brahe collected extensive observational data on planetary movements, particularly Mars, which Johannes Kepler later used to develop his laws of planetary motion. Brahe's accurate measurements allowed Kepler to show that planetary orbits are elliptical, not circular as previously believed, providing evidence against the Earth-centered theory.
Johannes Kepler was the scientist who included three laws of planetary motion as part of his heliocentric theory of the universe. These laws, known as Kepler's Laws of Planetary Motion, describe the orbits of planets around the Sun.
Geocentrism places Earth at the center of the planetary system. Heliocentrism, correctly, places the sun at the center, hence: the Solar System.
Isaac newton discovered the three principles of planetary motion
He didn't alter them. He showed that his theory of planetary motion under gravity was consistent with them.
