helliocentric - where the sun is the center of the universe.
In a geocentric universe the earth is the center of the universe or solar system and everything revolves around it. In a heliocentric universe the sun or a star is the center of the universe or solar system. We live in a heliocentric solar system with the sun as the center.
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
The Geocentric model
The geocentric model, also known as the Ptolemaic system, is a theory that was developed by philosophers in Ancient Greece and was named after the in science and technology, the geocentric model seems preposterous.
Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
In a book called On the Revolutions of the Heavenly Bodies (that was published as Copernicus lay on his deathbed), Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system. The ordering of the planets known to Copernicus in this new system is illustrated in the following figure, which we recognize as the modern ordering of those planets.For this reason, a heliocentric system is the Solar System with the sun in the center, so there is not an "opposite".
The Heliocentric System. m.i.
The proposed the heliocentric system.
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
earth
Geocentric model. This has earth at the centre. We now know this not to be true.
Geocentric means considering the Earth as the center.
It is the idea that the Earth is the center of the universe.
the heliocentric system and the geocentric system
One of them was Claudius Ptolemy. He made a geocentric model and called it Plotemy's system, it lasted 13 centuries.
In a geocentric universe the earth is the center of the universe or solar system and everything revolves around it. In a heliocentric universe the sun or a star is the center of the universe or solar system. We live in a heliocentric solar system with the sun as the center.
