which Scientist proved earth rotating around sun
There was a well-known debate in the history of Astronomy which was going on for a long time in the 15th, 16th and 17th century. Three centuries is what it took to be resolved, so you can imagine just how profound it was.
The debate was “Earth revolves around the Sun or the Sun revolves around the Earth?”
Humans had been watching day-in and day-out the Sun going from east to west. Space travel was not there. No modern instruments were present. No wonder that it was thought that the sun revolves around the earth. It was even thought that not just the sun, but the entire universe revolves around the earth.
Coming to the actual answer to your question, it was Nicolaus Copernicus, who first officially putforth the idea that the Earth revolved around the Sun and not vice versa. His theory was later supported by Galilio Galilei and Isaac Newton.
