The statement that best describes the location of the sun according to the heliocentric model of the universe is:
- The sun is located at the center of the universe.
However, it's important to note that in modern astronomical understanding, the sun is located at the center of the solar system (not the entire universe), with planets, including Earth, orbiting around it. Therefore, the ideal answer in the context of classical heliocentric theory would be that the sun is at the center of the solar system.
