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.
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.
heliocentric theory, the theory of evolution, relativity theory

Johan kepler.
if i nkew i wouldnt be asking!
Kepler
Copernicus believed the planetary motions were due to:
The dominant theory of the origin of the moon is the giant collision theory. It is wherein two planetary bodies collided, thus forming the moon.
Bohr.
Niels Bohr proposed the planetary model for the atom.
It appeared from flattened disk of gas and/or dust orbiting the sun.
It appeared from flattened disk of gas and/or dust orbiting the sun.
The Bohr model of an atom was of planetary type.
Geocentrism places Earth at the center of the planetary system. Heliocentrism, correctly, places the sun at the center, hence: the Solar System.
