Answer 1

Which planetary model allows a scientist to predict the exact positions of the planets in the night sky over many years?

A) The planets' orbits are circles in a geocentric model

B) The planets' orbits are circles in a heliocentric model

C) The planets' orbits are ellipses in a geocentric model

D) The planets' orbits are ellipses in a heliocentric model

Answer:

The planets' orbits are circles in a geocentric model is the planetary model allows a scientist to predict the exact positions of the planets in the night sky over many years.

Explanation:

• Ptolemy suggested that the model that the planets moving around the sun in a circular path. As the statement clearly explains that sun the middle of the solar system.
• Due to the gravitational pull of the sun, all the planets rotate around the sun in a circular path.
• All these are because of the universal law of gravitation. In the solar system, each planet has its path and they will rotate along with their path.
