Heart world model, this model are using five following ideas as theoretical basis: the sun will not be moved with fixed fixed star
；The earth moves round the sun；The track of the earth is circle；The sun is located at the center of the circle；Fixed fixed star apart from the sun with
The earth is extremely remote.Aristarchus is thought, due to the earth daily one week rotates around the sun, tellurian people just have day
Sky is around the impression of earth rotation, and therefore, it is sphere that he, which obviously understands the earth,.Aristarchus is also believed that if including that the earth exists
Interior planet all surrounds sun rotation, and the sun seems that volume does not change because of unlimited remote apart from the earth, then day
Body movement just can very easy be interpreted.The day heart world model of Aristarchus was too fashionable from the point of view of at that time, generation at that time
Boundary no one it will be appreciated that he, therefore he theory bury soon.
