Retrograde motion is caused by Earth moving _____ than other planets. Copernicus rediscovered Aristarchus's heliocentric model. His model had planets orbiting the _____ and the _____ orbiting Earth. This model explains the Sun's rising and setting is due to Earth's _____. His model was rejected because it went against _____ teachings.
Understand the Problem
The question involves filling in the blanks related to retrograde motion and Copernicus's heliocentric model, asking about the mechanics of planetary motion and historical astronomical theories.
Answer
faster, Sun, Moon, rotation, religious
Retrograde motion is caused by Earth moving faster than other planets. Copernicus's model had planets orbiting the Sun and the Moon orbiting Earth. This model explains the Sun's rising and setting is due to Earth's rotation. His model was rejected because it went against religious teachings.
Answer for screen readers
Retrograde motion is caused by Earth moving faster than other planets. Copernicus's model had planets orbiting the Sun and the Moon orbiting Earth. This model explains the Sun's rising and setting is due to Earth's rotation. His model was rejected because it went against religious teachings.
More Information
Copernicus's heliocentric model placed the Sun at the center of the solar system, simplifying the explanation of retrograde motion and challenging geocentric views.
Tips
A common mistake is to attribute retrograde motion to the actual reversal of the planet's motion rather than a perspective effect due to Earth's relative movement.
