Aristarchus

Alistair Kos lived around 310 BC. About 230 BC, Alistair Kos was the first Greek philosopher and mathematician who understood the solar system. Other people in front of him thought that Earth is moving with a ball, but he was the first person who understood the theory of the sun-centered that pointed out that the sun is in the middle. In 288 or 287 BC, he followed Theoftastas as the principal of an esoteric school founded by Aristotle. Aristarchus has only one book "About the size and distance of the sun and the moon". He estimated the diameter of the sun, about seven times the diameter of the earth, and estimated that the volume of the sun was about 300 times the diameter of the earth.

* Aristarchus * Aristarchus of Samos (310-330 B.C.), an astronomer often referred to as ancient Copernicus, laid the foundation for the sky scientific investigation. According to Archimedes' contemporary view, Aristotle is not only the first person to propose the world of mind but also suggests a larger universe than any of his predecessors. He wrote that Copernicus himself first praised Alistar Cos, De Revolution Bass, Kalestibus on his own cardboard. Perhaps Copernicus determined that his paper had its own merit.

Klein believes that the Greeks are responsible for appealing Samos' Aristax. Because they insist that the movement of the space reactor is not justified ... The only ancient astronomer named the Alicasta's heliocentric model is Celestas, which is one century after Alistar Kos It is a living Greek astronomer. According to Plutarch, Seleucus was the first person to prove the sun-centered system through reasoning, but he did not know what kind of argument he did. Seymour's claim on solar-centered cosmology may be related to tidal phenomena. According to Strabo (1.1.9), Seleucus is the first person who claimed that the tide is due to the attraction of the moon, the tide height depends on the position of the moon relative to the sun.

Greek astronomer Alicestars in Samos is the first scientist who was born in 270 BC and knew that the earth would go around the sun. Little is known about the childhood of Alistair Kos and his life. His only record was from Archimedes and Plutak. And they discussed his view on the movement of all the planets in the solar system. Unfortunately, the lack of advancement in technology has greatly influenced his observations, making them inaccurate, especially making his geometric equation inaccurate. The main contribution of Aristarchus is the more accurate scale of our solar system. Aristarchus of Samos is honored to have a lunar crater named after him. And it is also the brightest place of the moon.
