- Aristarchus of Samos (c. 310 - 230 BC) proposed a model that placed the Sun at the centre, that is a heliocentric Universe. His model would be familiar to us today as a reasonable description of the solar system.
- He was the first to say that the Sun, and not the Earth, was the focal point of our universe.
- Aristarchus figured out how to put the Sun in the nearby planetary group and he additionally positioned the planets organized appropriately from the Sun.
- He did this by noticing the Moon during a lunar obscuration and by assessing the point and the size of the Earth. He comprehended that the Sun, the Moon and the Earth structure a close to right point during the last and the principal quarter of the Moon.
- His hypothesis that the widths of the Moon and the Sun ought to be relative to their separation from the Earth is additionally legitimate however gave wrong outcomes. Today that the knowledge of Aristarchus and his commitment to science has been famous, researchers have given his name to a pit on the Moon.
- In view of this, he determined that the Sun was multiple times further away from Earth than the Moon. Be that as it may, he committed an error in his computations: he accepting the point as 87 degrees while the right point is 89â° 50'. Accordingly, the real distance is multiple times and not multiple times, as proposed by Aristarchus. Albeit the mathematical hypothesis is current, the counts weren't right because of absence of exact instruments instead of rationale.
