  2. Copernican principle - Wikipedia

    en.wikipedia.org/wiki/Copernican_principle

    While the Copernican principle is derived from the negation of past assumptions, such as geocentrism, heliocentrism, or galactocentrism which state that humans are at the center of the universe, the Copernican principle is stronger than acentrism, which merely states that humans are not at the center of the universe. The Copernican principle ...

    Newton’s powerful achievement was his construction of a natural philosophy of mathematizable forces in which the sun’s position at or near the center of the planets could be deduced rather than assumed as a premise, as Copernicus had done: “The Copernican system is proved a priori,” Newton wrote, “for if the common center of gravity ...

    Nicolaus Copernicus (1473–1543) formulated a heliocentric model of the universe. Nicolaus Copernicus had moved the Earth away from the center of the universe with the heliocentric theory for which he presented evidence in his book De revolutionibus orbium coelestium (On the revolutions of the heavenly spheres) published in 1543.

    en.wikipedia.org/wiki/Copernican_Revolution

    While Copernicus's work sparked the "Copernican Revolution", it did not mark its end. In fact, Copernicus's own system had multiple shortcomings that would have to be amended by later astronomers. Copernicus did not only come up with a theory regarding the nature of the Sun in relation to the Earth, but thoroughly worked to debunk some of the ...

    en.wikipedia.org/wiki/Commentariolus

    The Commentariolus (Little Commentary) is Nicolaus Copernicus's brief outline of an early version of his revolutionary heliocentric theory of the universe. [1] After further long development of his theory, Copernicus published the mature version in 1543 in his landmark work, De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres).

  8. Three-body problem - Wikipedia

    en.wikipedia.org/wiki/Three-body_problem

    The circular restricted three-body problem [clarification needed] is a valid approximation of elliptical orbits found in the Solar System, [citation needed] and this can be visualized as a combination of the potentials due to the gravity of the two primary bodies along with the centrifugal effect from their rotation (Coriolis effects are ...

  9. Deferent and epicycle - Wikipedia

    en.wikipedia.org/wiki/Deferent_and_epicycle

    Another complication was caused by a problem that Copernicus never solved: correctly accounting for the motion of the Earth in the coordinate transformation. [12]: 267 In keeping with past practice, Copernicus used the deferent/epicycle model in his theory but his epicycles were small and were called "epicyclets".
