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.

Respuesta :

The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

What are the laws of Kepler?

There are three laws, made by the Kepler, to explain the motion of the planet around the sun.

  • First Law-According to this law, all the planets moves in the elliptical orbits. The center of this orbital path is the Sun. Thus Planetary orbits are elliptical.
  • Second Law-The planet moves in elliptical orbit. The line of planet and sun sweeps out equal mass in equal time.
  • Third Law-The square of the period of a planet to complete one path of electrical orbit is directly proportional to the cubes of semi-major axis of their orbit.

Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.

Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).
