The proposed the heliocentric system.
Brahe believed in a geocentric worldview. In spite of his challenge against older ideas that the heavens were changeable, he opposed Copernican heliocentricism.
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
The geocentric. The two systems were the geocentric and heliocentric, the former with the earth at the solar system's center, and the latter with the sun. Because Copernicus championed the latter, it is often called the Copernican model.
The Heliocentric System. m.i.
The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
the heliocentric system and the geocentric system
Heliocentric = The Sun is at the center of our solar system. Geocentric = The Earth is at the center of our solar system. Insisting the Sun is at the center, which it is, once very much angered the church.
The name for the model of a solar system in which planets (and the Sun) revolve around the Earth is called geocentric. Modern astronomy rejects the idea, dating back to Copernicus who was a proponent of the notion that the planets orbited around the Sun (heliocentric). The heliocentric model is thus also called the Copernican, and the geocentric (with models presented most famously by Aristotle and Ptolemy) is called the Ptolemaic.
The phases of Venus are well supported by the heliocentric system, but they are also supported very well by the previous geocentric system. All you need for Venus to have phases is that Venus should pass between Earth and Sun. That happens in both the heliocentric system and the geocentric system.
