In 3-5 sentences, describe how Copernicus developed his model of the solar system. In your answer, include an explanation for why his model was, or was not, readily accepted at the time.

Copernicus developed his model of the solar system by proposing that the Earth revolves around the Sun, contrary to the prevailing belief of a geocentric system. He spent several decades studying and analyzing astronomical observations, mathematical calculations, and ancient texts before publishing his groundbreaking book "De Revolutionibus Orbium Coelestium" in 1543. However, his model faced resistance due to its deviation from the long-accepted Ptolemaic geocentric model deeply rooted in religious beliefs, as well as the lack of strong evidence at the time to support his theory. Additionally, the complexities of his model and the absence of immediate empirical proof made it challenging for people to readily accept his revolutionary idea.
