8. Each statement describes today's accepted Heliocentric model of our solar system EXCEPT:
*
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.
The statement that describes today's accepted Heliocentric model of our solar system EXCEPT is "The planets orbit the sun in nested spheres."
To determine the correct answer, we need to evaluate each statement and identify the one that does not describe today's accepted Heliocentric model of our solar system.
Statement 1: "The sun is in the center of our solar system."
This statement accurately describes the Heliocentric model. In this model, the sun is recognized as the central body, around which the planets orbit.
Statement 2: "Each planet's orbits around the sun in an ellipse."
This statement is also correct. According to Kepler's laws of planetary motion, each planet's orbit around the sun is an ellipse, with the sun located at one of the foci of the ellipse.
Statement 3: "The planets orbit the sun in nested spheres."
This statement is incorrect. According to the Heliocentric model, the planets do not orbit the sun in nested spheres. Instead, each planet has its own unique elliptical orbit around the sun.
Statement 4: "All planets, including Earth, orbit the sun."
This statement is true and aligns with the Heliocentric model. All planets, including Earth, revolve around the sun in individual elliptical orbits.
Based on the explanations above, we can determine that the answer is the statement "The planets orbit the sun in nested spheres," because it does not describe today's accepted Heliocentric model of our solar system.
