As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects.
These schemes, which were based on geometry rather than the arithmetic of the Babylonians, would eventually eclipse the Babylonians' theories in complexity and comprehensiveness, and account for most of the astronomical movements observed from Earth with the naked eye.
Several thousands of planets around other stars ("extrasolar planets" or "exoplanets") have been discovered in the Milky Way.
As of 1 September 2019, 4,109 known extrasolar planets in 3,059 planetary systems (including 667 multiple planetary systems), ranging in size from just above the size of the Moon to gas giants about twice as large as Jupiter have been discovered, out of which more than 100 planets are the same size as Earth, nine of which are at the same relative distance from their star as Earth from the Sun, i.e. The idea of planets has evolved over its history, from the divine lights of antiquity to the earthly objects of the scientific age.
it was almost universally believed that Earth was the center of the Universe and that all the "planets" circled Earth.
The reasons for this perception were that stars and planets appeared to revolve around Earth each day The first civilization known to have a functional theory of the planets were the Babylonians, who lived in Mesopotamia in the first and second millennia BC.
