What is Heliocentric Model?
The astronomical model where in the sun is at the center of the earth and all the other planets move around the sun.
The ancient India were aware that the earth and all the other planets in the solar system moved around the sun. This is Heliocentric Model.
Ancient Hindu temple dating back to 5000 years used to have ‘Navagraha Mantap’ where in the Sun would be placed in the center and all the other planatery gods would revolve around the sun. This Navagrah mantap is stil followed till date. Hence this clearly indicates that our ancestors clearly knew about heliocentric model.
Arayabhatta also proposed the theory where in the earth rotates in its own axis and also proposed Heliocentric Model wherein he stated that the earth revolves around the sun and not the sun revolving around the earth. Aryabhatta uses the theory of the big and the small (‘Laghava gaurava nyaya’)
Guru= Bid/ Weighty which could means a teacher or Acharya.
If the Acharya is the Guru the student is the Laghu. It is a well established fact that the Guru is his higher than student, and it always the student goes around. This is
‘Laghava gaurava nyaya’
In our model:
Sun larger than earth
Hence the earth would orbit the sun and not the other way around.
To anyone who stands and looks at sky, it looks clear that earth stays in one place and all the celestial bodies in the sky looks like it goes around the earth every day.
But after certain observations by our ancestors, they proposed heliocentric model in the form of Sanskrit verses in our Vedas.
Aristarchus was the first person the modern age to proposed heliocentric model.
He estimated that the sun was six to seven times bigger than the earth. His writings about the heliocentric theory were lost in time but, the commentary by his contemporaries on his work still survives.
Until 16th Century that geometric model was accepted, it was only when Nicolaus Copernicus (1543 AD) proposed heliocentric model. In the coming century Jonhanssen Kepler explained about the heliocentric model. Heliocentric word comes from the Greek. Helious=Sun; Kentron= Center.
