Why does Aristarchus theory of the sun is much larger than Earth support the heliocentric theory of the solar system?

According to modern understanding, the planets, and the Sun, move around the Solar System's center of mass. Since the Sun is much more massive than the planets, this center of mass is very close to the Sun.
If the Sun is much larger than any of the planets, it seems likely that it also has a greater mass - assuming that their respective densities are somewhat similar. And indeed, this is the case here.

How do you used heliocentric in a sentence?
Aristarchus, in the 3rd century BC, was the first to postulate that our Solar System is heliocentric. Later, in 1743, Copernicus advanced the same hypothesis, but in a more comprehensive form.
Was Aristotle the first to propose the sun was the center of the universe?
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.
Who presented the first heliocentric model of the solar system?
Copernicus
When did aristarchus of samos propose his heliocentric model why wasn't it accpted at the time?
Aristarchus of Samos proposed his heliocentric model in the 3rd century BCE, around 240 BC. His model suggested that the Earth and other planets revolved around the Sun, with the Earth itself rotating on its axis. However, Aristarchus' heliocentric model was not widely accepted during his time, and there were several reasons for this: Lack of direct evidence: Aristarchus' heliocentric model was a radical departure from the prevailing geocentric model, which held that the Earth was at the center of the universe and all celestial bodies, including the Sun, orbited around it. Aristarchus' model lacked direct observational evidence to support it, and the apparent motion of the stars and planets seemed to align more closely with the geocentric model. Limited understanding of celestial mechanics: In Aristarchus' time, the understanding of celestial mechanics was not as advanced as it would become in later centuries. The concept of elliptical orbits and gravitational forces, which later helped explain planetary motion in a heliocentric model, had not been developed. Philosophical and religious beliefs: The geocentric model was deeply rooted in ancient philosophical and religious beliefs. The idea of Earth being at the center of the universe was consistent with the notion of humans being the central and most important beings in creation. Aristarchus' heliocentric model challenged this worldview, making it harder for people to accept. Lack of telescopic technology: The heliocentric model gained more support after the invention of the telescope in the 17th century. The telescope allowed astronomers like Galileo Galilei to make more detailed observations of the planets, providing evidence that supported the heliocentric model. However, during Aristarchus' time, telescopic technology was not available, so he could not provide the observational evidence needed to convince others of his model's validity. As a result of these factors, Aristarchus' heliocentric model was largely ignored and overshadowed by the geocentric model for many centuries. It wasn't until the work of Nicolaus Copernicus in the 16th century and later advancements in astronomy that the heliocentric model gained wider acceptance and eventually became the prevailing view of the solar system.
What was the name of the Scientist who proposed the Helicentric Model?
The earliest known proposal that the Sun was at the center of our solar system while the planets moved around it was by Aristarchus of Samos, a Greek mathematician and astronomer who lived in the 3rd century BC. (Others may have proposed it earlier, but no reference to them remains after 2400 years.) However, the views of Aristotle proved easier to accept. It wasn't until Copernicus developed the same theory (probably independently) based on more accurate and complete observational data that the heliocentric view of the solar system was widely accepted.
Who made the heliocentric solar system?
The first person to theorize a heliocentric solar system was Aristarchus, a greek philosopher. However, he was ridiculed, and the first person to have the idea accepted was Copernicus.
What significant scientific conclusions did Aristarchus reach?
The scientific conclusion that Aristarchus reached was presenting the first heliocentric model of the solar system, His model showed the Sun and Earth in the center of the universe.
Who proposed the first heliocentric model of the solar system?
Aristarchus of Samos, a Greek mathematician and astronomer, about 2300 years ago.

What are the geocentric and heliocentric theories of the universe?
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
Did The idea of a heliocentric view of the solar system originated with Copernicus?
Rejected by his contemporaries and ignored for 18 centuries, Aristarchus of Samos proposed the first serious model of a heliocentric solar system. You may read about it in Archimedes' book, "The Sand Reckoner".

How did Aristarchus change the world?
He was the first person to present an explicit argument for a heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe
Who discovered heliocentric cosmology?
Nicolaus Copernicus The above answer is incorrect. Copernicus only proved what Aristarchus already discovered, however at that time people rejected his theory since Aristotle was more popular in terms of science than he was. "He presented the first known heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe...The heliocentric theory was successfully revived nearly 1800 years later by Copernicus" Aristarchus is the correct answer
