8. Each statement describes today's accepted Heliocentric model of our solar system EXCEPT:
*
1 point
The sun is in the center of our solar system
Each planet's orbits around the sun in an ellipse
The planets orbit the sun in nested spheres
All planets, including Earth, orbit the sun
The planets orbit the sun in nested spheres is not a statement that describes today's accepted Heliocentric model of our solar system.
The correct answer is: The planets orbit the sun in nested spheres.
To determine the correct statement that does not describe today's accepted Heliocentric model of our solar system, we need to review the characteristics of this model.
The Heliocentric model, which was proposed by Nicolaus Copernicus in the 16th century and further developed by Johannes Kepler and Isaac Newton, states that the sun is at the center of our solar system, and the planets orbit around it. Here are the descriptions of the statements provided:
1. The sun is in the center of our solar system: This statement is correct and aligns with the Heliocentric model.
2. Each planet's orbits around the sun in an ellipse: This statement is also correct. In the Heliocentric model, the planets' orbits are elliptical, with the sun located at one of the foci of each ellipse.
3. The planets orbit the sun in nested spheres: This statement is incorrect. The Heliocentric model does not involve nested spheres. Instead, it describes the planets as moving in elliptical orbits.
4. All planets, including Earth, orbit the sun: This statement is true and consistent with the Heliocentric model. According to this model, all planets, including Earth, revolve around the sun.
Based on the above explanation, the statement that does not describe today's accepted Heliocentric model of our solar system is: "The planets orbit the sun in nested spheres."
