20. The diagram below shows a model of the solar system. Which of the following statements is correct about this model?

This is the heliocentric model of the solar system and it was created by Aristotle.
This is the geocentric model of the solar system and it was created by Kepler.
This is the heliocentric model of the solar system and it was created by Kepler.
This is the geocentric model of the solar system and it was created by Aristotle.

This is the geocentric model of the solar system and it was created by Aristotle.

The correct statement is: This is the heliocentric model of the solar system and it was created by Kepler.

To determine which statement is correct about the model of the solar system depicted in the diagram, we need to understand the different models and their creators.

1. Heliocentric model: This model proposes that the Sun is at the center of the solar system, with the planets, including Earth, orbiting around it.

2. Geocentric model: This model suggests that Earth is at the center of the solar system, with all the other celestial bodies orbiting around it.

Now, let's find out who created these models:

1. Aristotle: Aristotle, an ancient Greek philosopher, proposed a geocentric model of the solar system. According to his model, Earth was stationary at the center.

2. Kepler: Johannes Kepler, a German astronomer, developed the heliocentric model based on the observations and mathematical calculations of his contemporary, Tycho Brahe.

Considering this information, we can conclude that the correct statement about the model depicted in the diagram is:

- This is the heliocentric model of the solar system, and it was created by Kepler.

Therefore, the third statement is correct: "This is the heliocentric model of the solar system, and it was created by Kepler."
