Step 1: Break Down the Problem

We need to determine which model of the solar system was proposed by Copernicus. The options provided are:

1. Ethnocentric
2. Geocentric
3. Heliocentric
4. Lunocentric

Step 2: Relevant Concepts

• Geocentric: This model places the Earth at the center of the universe, with all celestial bodies orbiting around it.
• Heliocentric: This model places the Sun at the center of the solar system, with the Earth and other planets orbiting around it.
• Ethnocentric: This term generally refers to evaluating other cultures based on the standards of one's own culture, and is not applicable in this context.
• Lunocentric: This term, if used, would imply a model centered around the Moon, which is not one of the recognized models of the solar system.

Step 3: Analysis and Detail

Copernicus is best known for his significant contribution to astronomy in the 16th century, where he proposed the Heliocentric model. This model was revolutionary because it challenged the long-standing Geocentric model that placed the Earth in the center of the universe.

Step 4: Verify and Summarize

Based on historical context and Copernicus' work, the Heliocentric model is the accurate answer. The term "heliocentric" is derived from the Greek words for sun (helios) and center (kentron), emphasizing the Sun's central position in this model.

Final Answer

The correct answer is Heliocentric.
