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
<u>Answer:</u>
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.
<u>Explanation:</u>
- 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.
