Later, Heraclides (330 B.C.) developed the first Solar System model, placing the planets in order from the Earth it was is now called the geocentric solar system model .
What is the old solar system model called?
An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model.
What was the name of solar system model that was first developed and believed true?
The Copernican Model : A Sun-Centered Solar System. The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years. Then, in the 16th century a “new” (but remember Aristarchus) idea was proposed by the Polish astronomer Nicolai Copernicus (1473-1543).

Rejected by modern science, the geocentric theory (in Greek, ge means earth), which maintained that Earth was the center of the universe , dominated ancient and medieval science. It seemed evident to early astronomers that the rest of the universe moved about a stable, motionless Earth.
Who invented Geocentrism?
The most highly developed geocentric model was that of Ptolemy of Alexandria (2nd century ce). It was generally accepted until the 16th century, after which it was superseded by heliocentric models such as that of Nicolaus Copernicus.
Is heliocentric model correct?
In the 1500s, Copernicus explained retrograde motion with a far more simple, heliocentric theory that was largely correct . ... Thus, retrograde motion occurs over the time when the sun, Earth, and planet are aligned, and the planet is described as being at opposition – opposite the sun in the sky.
