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
Theory-practice-theory take existing theory in education, apply to distance learning, develop new theory Practice-research-theory see what is happening in distance learning, submit to research, develop theory from results Theory-theory-research/practice build on an initial theory to develop a second theory, then apply and test it
A common theory is a theory which has not been proven or a theory without evidence.

if i nkew i wouldnt be asking!

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.
