What modifications did Kepler make to Copernicus’s model? Select two options.

Planetary orbits are elliptical.
Planets closer to the Sun move faster.
Planets spin in an epicycle while orbiting Earth.
Venus has phases due to its orbiting of the Sun.
Earth’s rotation causes the rising and setting of the Sun.

Kepler made below modifications :

Planetary orbits are elliptical.

Planets closer to the Sun move faster.

Explanation:

Copernicus proposed Heliocentric model of the universe. This model suggested that all planets, stars including the Earth revolve around the Sun.

He also said that stars are still in the universe. Their daily motion that we see from the Earth is because of the continuous rotation of the  Earth.

As per Copernicus, Earth takes spherical path around the Sun. This concept was later modified by Kepler.

Kepler defined the exact orbit path of the Sun. He proposed Laws Of Planetary Motion. These laws explains the three laws that planets orbit obey.

Kepler suggested that planets move in elliptical orbits around the Sun and those which are near to the Sun move faster.
