Which represents the copernican model that is most similar to that of aristarchus?
jeyben [28]

The Copernican model that is most similar to that of Aristarchus is where the solar system shows the planets in their orbits around the sun in the order: Mercury, Venus, Earth with Moon, Mars, Jupiter, Saturn.

Aristarchus of Samos was a Greek astronomer who argued that the earth rotates on its axis and revolves around the sun. He had suggested a new theory that, if true, would make the universe much larger than was believed at the time. In the 16th century, Aristarchus inspired the Polish astronomer Nicholas in his Copernicus’s studies.

However, Copernicus later erased this reference, and Aristarchus' theory was not mentioned in the book published by him. Copernicus His model is the system of planetary motion maintained by Copernicus, in which the earth revolves once in a day and around the sun once in his year, while the other planets also has an orbit centered near the sun.
