What is a feature of the modern model of the solar system that was not found in the future models the stars are not part of our solar system to circular orbits a year with approximately 365 days Earth at the center

One feature of the modern model of the solar system that was not found in the previous models is the understanding that the Earth is not at the center of the solar system. In earlier models, such as the geocentric model proposed by Ptolemy, it was believed that Earth was the center of the universe, with the Sun and other celestial bodies orbiting around it. However, in the modern model, known as the heliocentric model, it is understood that the Sun is at the center of the solar system and the Earth, along with other planets, revolves around it. This shift in perspective was brought about by the contributions of scientists like Nicolaus Copernicus and Johannes Kepler in the 16th and 17th centuries.
