A student is looking at a current model of the solar system. Which of these BEST describes the model she sees A. a geocentric model, which means Earth is center of the solar system B. a heliocentric model, which means Earth is the center of the solar system C. a geocentric model, which mean Sun is center of the solar system or D. a heliocentric model, which mean Sun is center of the solar system.

D. a heliocentric model, which mean Sun is center of the solar system.

D. a heliocentric model, which means Sun is the center of the solar system.

Just think of it like this: the Sun is the sunshine of the solar system's life! So it only makes sense for it to be the center of attention. Move over, Earth!

D. a heliocentric model, which means the Sun is the center of the solar system.

To determine the correct answer, we need to understand the difference between a geocentric and a heliocentric model of the solar system.

A geocentric model believes that Earth is at the center of the solar system, with the Sun, Moon, and other celestial objects revolving around it. On the other hand, a heliocentric model states that the Sun is at the center of the solar system, and all planets, including Earth, orbit around it.

Given these definitions, we can eliminate options A and B, which both suggest that Earth is the center of the solar system. This leaves us with options C and D, which mention the Sun as the center but differ in whether the model is geocentric or heliocentric.

Therefore, the correct answer is: D. a heliocentric model, which means the Sun is the center of the solar system.
