Heliocentric model of Aristarch Samossky (III c. B.C.).

Heliocentric model

The Moon turns around the Earth. The Earth rotates around its axis, that is why the cauge of day and night can be seen. The Earth and the other planets turn around the Sun - the world centre. Aristarch model explained the modification of Venus and Mars glitter. In B1 position Venus is seen as a round dark spot on the Sun's disk; in B2 position it is seen as a bright spot of assimetric form. In M1 position Mars is nearer to the Earth and has more bright glitter than in M2 position.
