Aristarchus of Samos
The astronomer credited as the first to theorize that the planets orbit around the Sun (heliocentrism) is Nicolaus Copernicus. He developed the heliocentric model of the solar system, which proposed that the Sun was at the center and the planets, including Earth, revolved around it in circular orbits. This theory was a departure from the earlier geocentric model, which posited that Earth was at the center of the universe and everything orbited around it. Copernicus's work laid the foundation for the modern understanding of the solar system's structure and motion.

Copernicus, but he also believed the sun was the center of the universe which wasn't completely correct either.
Because the ancient Greek astronomers were one of the first astronomers to discover the planets. As they looked at the planets over time they moved into different places. The planets seemed o orbit the Sun so the Greek astronomers called them planets, which meant :wanderers.

Johannes Kepler was the first to state that planets move in elliptical orbits.

it was geilo i dont know his last name but if youu know him than well i dont know check your books kids.
He first suggested that the Earth (and the other planets that were then known) rotated around the Sun instead of the other way around.

It was Claudius Ptolemy, 98-160. His Ptolemaic system describing the planets' movements among the stars was generally accepted for about 1400 years. Until the computer age, the Ptolemaic model was also used in planetariums.
It was Johannes Kepler.
Aristrachus of SamosThe first man to theorize that the Earth revolved around the sun is believed to be Nicolas Copernicus. In the 1500s he speculated that rather than the sun circling the Earth, the Earth may actually orbit the sun.
