What is heliocentric?

Answer 1

In astronomy, heliocentrism is the belief that the Sun is at the center of the Universe and/or the Solar System. The word is derived from the Greek (Helios = "Sun" and kentron = "Center"). Historically, heliocentrism is opposed to geocentrism and currently to modern geocentrism, which places the earth at the center. (The distinction between the Solar System and the Universe was not clear until modern times, but extremely important relative to the controversy over cosmology and religion.) In the 16th and 17th centuries, when the theory was revived and defended by Copernicus, Galileo, and Kepler, it became the center of a major dispute.

To anyone who stands and looks at the sky, it seems clear that the earth stays in one place while everything in the sky rises and sets or goes around once every day. Observing over a longer time, one sees more complicated movements. The Sun makes a slower circle over the course of a year; the planets have similar motions, but they sometimes turn around and move in the reverse direction for a while (retrograde motion). As these motions became better understood, they required more and more elaborate descriptions, the most famous of which was the Ptolemaic system, formulated in the 2nd century.

Answer 4

What Is Heliocentric

Answer 5

Heliocentric refers to the sun being in the center of the universe. Later, this was found out not to be true. The sun is the center of the solar system, but not the universe.

Answer 6

Helios = Greek name for the sun god.
Centric = does that need explaining? Of or at the center.

Heliocentric = sun centered, as opposed to geocentric (Earth centered) arrangement of the planets posited by Abrahamic scriptures.

Answer 7

Compernicus was a platonist. That's part of it. But basically, the old system of astronomy was based on something called the Ptolemeac model. There is one problem, however: For instance, if you assume the earth to be at the centre of things, certain objects reverse direction at predictable times. The ptolemeac moddle attempted to solve this by a complicated system of epicentres: Circles withing circles. But Copernicus, partly inspired by platonism, believed in a more elegant solution. There is some Occam Razor in there, but the principles are still shaky at this point in the history of science. He finds out that by placing the sun at the centre of the model of the planets, he solves a LOT of problems.

Answer 9

It is a system that recognizes the sun as the center of our universe.

Galileo first proposed that based on his observations but was forced to deny that it was true back in the days when church and state were not separate.
