Question

What is a feature of the modern solar system that was not found in ancient models?

Answer 1

One feature of the modern solar system that was not found in ancient models is the understanding of the heliocentric model. Ancient models, such as the geocentric model proposed by Ptolemy, believed that the Earth was at the center of the universe and all celestial bodies revolved around it. In contrast, the modern solar system model is based on the understanding that the Sun is at the center, and the planets, including Earth, orbit around it. This shift from a geocentric to a heliocentric model was a significant advancement in our understanding of the solar system.
