One feature of the modern model of the solar system that was not found in ancient models is the concept of heliocentrism, which proposes that the Sun is at the center of the solar system and the planets, including Earth, revolve around it. In contrast, ancient models, such as the Ptolemaic model, suggested a geocentric system where Earth was believed to be at the center, with the Sun, planets, and other celestial bodies orbiting it. The shift from the geocentric to the heliocentric model was a significant advancement in our understanding of the solar system.
