Which historical figure was accused of heresy for their findings regarding the solar system?

The figure who was most notably accused of heresy for their findings regarding the solar system is Galileo Galilei. Galileo supported the heliocentric model proposed by Copernicus, which posited that the Earth and other planets revolve around the Sun. His advocacy for this model, particularly after making telescopic observations that reinforced it, led to conflict with the Catholic Church. In 1616, he was admonished for promoting this view, and ultimately, in 1633, he was tried by the Roman Inquisition and found "vehemently suspect of heresy."

Although Copernicus also proposed the heliocentric theory, his ideas were published in "De revolutionibus orbium coelestium" in 1543, before Galileo's time, and he did not face heresy charges during his lifetime. Newton and Aristotle are not directly linked to accusations of heresy regarding the solar system; Newton's work in the 17th century focused more on gravity and motion, while Aristotle's views were rooted in a geocentric cosmos, which was later challenged but not in the same context as the early modern scientific revolution. Therefore, Galileo's prominent trial and condemnation by the Church highlight him as the correct answer in relation to her
