While the idea of a heliocentric model (Sun-centered) was controversial and challenged by the Church, the famous astronomer Nicolaus Copernicus, who proposed this model, died peacefully in his bed in 1543. He was not punished for his ideas.
It was Giordano Bruno, an Italian philosopher and Dominican friar, who was burned at the stake in 1600. However, his execution was not solely due to his support of the heliocentric model. Bruno was also a controversial figure who held various unorthodox religious and philosophical beliefs, which ultimately led to his conviction for heresy.
While the heliocentric model faced significant resistance from the Church, it was primarily through Galileo Galilei's observations and writings that the model gained wider acceptance. Galileo was put on trial by the Inquisition in 1633 and sentenced to house arrest for defending the heliocentric model, but he was not burned at the stake.
The history of the heliocentric model and the Church's response to it is complex and nuanced. While the Church did initially oppose this idea, it is inaccurate to say that anyone was burned at the stake solely for claiming that the Earth revolves around the sun.
