My answer is A. could anyone tell me if that's right ?
One feature of the modern model of the solar system that was not found in ancient models is the understanding that Earth is not at the center of the solar system. In ancient models, such as the geocentric model of Ptolemy, it was believed that Earth was the center of the universe and that all other celestial bodies revolved around it. However, in the modern model, known as the heliocentric model, it is understood that the Sun is at the center of our solar system and that Earth, along with other planets, orbits around it.
The correct answer is "stars are not a part of our solar system." In ancient models of the solar system, such as the geocentric model proposed by Ptolemy, it was believed that the Earth was at the center and that all celestial bodies, including the stars, revolved around it. However, in the modern model of the solar system, known as the heliocentric model, it is understood that the Sun is at the center, and the planets, including the Earth, revolve around it. Stars are actually located outside of our solar system, at vast distances from the Sun and its planets. To determine this answer, you would need to compare the ancient and modern models of the solar system to identify the difference.
