Ptolemy created the Geocentric model in 2AD
Copernicus challenged Aristotle's theories of planetary motion due to observations that didn't align with the geocentric model, particularly the retrograde motion of planets. Through his own observations and mathematical calculations, Copernicus proposed a heliocentric model where the Earth and other planets revolve around the Sun, providing a simpler explanation for the observed phenomena in the sky.

Kepler deviated from Aristotle's belief in circular orbits and Copernicus's uniform circular motion by proposing that planets move in elliptical orbits around the Sun, with the Sun at one focus of the ellipse. This marked a significant shift in understanding celestial motion, emphasizing that planetary speeds vary, being faster when closer to the Sun and slower when farther away. Kepler's First Law thus introduced a more accurate model of planetary motion that contradicted the long-held Aristotelian and Copernican views of perfect circularity.
Isaac newton discovered the three principles of planetary motion
Copernicus used perfect circles for the orbits of the planets.

The planetary model of an atom is simple. The nucleus is the planet and the electrons are the moons in the model.
The planetary model of the atom was proposed by Ernest Rutherford in 1911. This model suggested that electrons orbit the nucleus in a way that is similar to the planets orbiting the sun.
The heliocentric model proposed by Nicolaus Copernicus in the 16th century provided a theoretical framework for understanding planetary motion around the Sun. This model was further supported by Johannes Kepler's laws of planetary motion and Isaac Newton's law of universal gravitation. Observations made through telescopes and spacecraft missions have confirmed the heliocentric model, providing evidence that planets do indeed orbit the Sun.

I guess not. Niels Bohr created the Bohr model and the element named after him is bohrium. That's why he's so famous?
