What significant scientific conclusions did aristarchus an astronomer reach?
Aristarchus of Samos was one of the first Greek astronomers to propose a heliocentric model of the solar system, with the Sun at the center instead of the Earth. He also accurately estimated the sizes of the Sun, Earth, and Moon, and calculated the distance to the Moon using lunar eclipses. His work laid the foundation for later astronomers, such as Copernicus, who expanded on the heliocentric model.
Who said the planet goes around the solar system?
Galileo Galilei is credited with the observation that the planets orbit the sun rather than the sun orbiting the Earth. However, Aristarchus of Samos proposed the concept first in the 3rd century BC.
Who theorized that the planets revolved around the sun?
Nicolaus Copernicus was the astronomer who theorized that the planets revolved around the sun in a heliocentric model. His work "De revolutionibus orbium coelestium" laid the foundation for modern astronomy.
When did aristarchus of samos propose his heliocentric model why wasn't it accpted at the time?
It probably was accepted; locally. There were many philosophers in Greece at the time, and each one was popular in his City. Greek people were not much bothered by scientific evidence. They usually went along with whoever was the most popular and the most eloquent. In matters of astronomy, those were Archimedes and Ptolemy. They were so popular that when Cleanthes (of the Stoics) heard about the teachings of Aristachus, he wanted him banned. (Today, we'd say he wanted to prosecute him for spreading falsehoods). But we do not know exactly when Aristarchus proposed his model. In fact, the very few writings we have about it come from others (e.g., Archimedes). This would place the proposal around the year 240 BC.
Who was the first to believe that all planets except Earth orbit the sun?
I'm not aware that any observer EVER argued that "all planets except Earth" orbited the Sun. The first person we know of to argue that the Sun was the center of things, and that the Earth orbited the Sun, was Aristarchus of Samos, a Greek astronomer and mathematician about 2400 years ago.
Who was the astronomer from Samos who claimed that the sun was the center of the universe?
The astronomer from Samos who claimed that the sun was the center of the universe was Aristarchus of Samos. He proposed this heliocentric model around the 3rd century BCE, but it was not widely accepted in his time.
Who proposed a heliocentric model of the universe in which the planets revolve at different speeds around the sun?
Aristarchus of Samos
What scientist proposed a heliocentric model of the universe and the theory was rejected?
Aristarchus of Samos was the first person (that we know of!) that proposed a heliocentric model of the universe, as early as about 200B.C). His model was rejected mainly because of Aristotle's influence.Copernicus was the next person to propose a heliocentric model of the universe which was published in 1547. although very controversial at that time, this model was the one that caught on.
Who proposed the first heliocentric model of the solar system?
Aristarchus of Samos, a Greek mathematician and astronomer, about 2300 years ago.

Who was known as the Hellenistic Copernicus?
Aristarchus of Samos was known as the Hellenistic Copernicus for proposing a heliocentric model of the solar system in the 3rd century BCE, long before Nicolaus Copernicus in the 16th century. Aristarchus suggested that the Earth and planets revolve around the Sun, but his ideas were not widely accepted in his time.
Did aristarchus say the earth was the center of the universe?
No, Aristarchus of Samos proposed a heliocentric model of the universe with the Sun at the center and the Earth revolving around it. This idea was contrary to the prevalent geocentric model at the time.
Copernicus patterned his concept of the solar system after that of?
Copernicus's concept of the solar system was influenced by the ancient Greek astronomer Aristarchus of Samos, who proposed a heliocentric model in which the Earth and other planets revolved around the Sun. Copernicus built upon this idea and formulated his own heliocentric model in the 16th century.
What ancient astronomer developed a model of the universe?
Aristarchus of Samos, a Greek mathematician and astronomer, was the first person (that we know of) to propose the idea that the Earth circles the Sun
Who was first to say the sun is at the center?
Ancient Greek philosopher Aristarchus of Samos is the first known individual to propose that the Sun is at the center of the solar system. His heliocentric model challenged the prevailing geocentric view of the universe.
Who did aristarchus influence?
Aristarchus of Samos influenced later astronomers by proposing a heliocentric model of the universe, where the Sun, not the Earth, was at the center. His ideas laid the foundation for the work of astronomers like Copernicus and Galileo.
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".
