The astronomer Aristarchus of Samos was one of the most influential. Born in the 6th century BC, he lived in Greece during the Dark Ages. The Greeks believed that the Earth was the centre of the universe and that the Sun, Moon, and planets surrounded. The Earth revolves around the Sun according to Aristarchus. It was the main breakthrough in nature. The foundation for modern astronomy was laid by this discovery. The first person to realize that the moon revolves around the earth was Aristarchus [1]. Tracking the position of the Moon in the sky over time, allowed him to estimate its size. His theory was debated in the scientific community for centuries after he died. Aristarchus was correct about both theories, according to modern science. …show more content…
He is considered one of the most influential contributors in the history of astronomy. The Greeks believed that the Earth was the center of the macrocosm and that the Sun, Moon, and globes revolved around it. Still, Aristarchus challenged this idea and proposed that the Earth actually revolved around the Sun [2]. This was a major advance in the field of astronomy and marked the morning of ultramodern astronomy. Aristarchus was the first person to realize that the Moon revolves around the Earth. By tracking the position of the Moon in the sky over time, he was able to estimate its size, a proposition that was debated in the scientific community for centuries after his death. Nonetheless, Aristarchus was correct about both of his propositions, his contributions to astronomy are considered important to this day and have been used as the foundation for astronomy. The fine styles used by Aristarchus to study the positions and movements of the stars give substantiation for the heliocentric model. One of the tools he used was a gnomon, a perpendicular rod that casted a shadow, which he used to measure the angles between the Sun, Earth, and Moon during a lunar eclipse. He also made compliances with solar and lunar eclipses which allowed him to estimate the relative sizes of the Sun and Moon [2]. Likewise, generations of scientists have been inspired by his approach to studying the macrocosm and his work has had a continuing impact on
