Question

A student made the following observations about astronomical bodies.

Answer 1

Answer:

  C. Both observation 1 and observation 2.

Explanation:

  The heliocentric model states that the Earth and planets revolve around the Sun at the center of the Solar System.

  Observation 1 was answered by Nicolas Copernicus, father of the heliocentrism, in 1543. The reverse effect is an illusion created because the Earth revolves faster around the Sun than Mars.

 And observation 2 also is explained by the model because the rotation of the earth made that the Stars be closer to it at different times of the year.

  I hope this answer helps you.

Answer 2

I would say C. Stars would seem brighter as Earth moved nearer and the retrograde motion of Mars is due to Earth passing the planets.
