How did kepler’s discoveries contribute to astronomy? they supported the heliocentric model. they established the laws of planetary motion. they explained how the sun rises and sets. they made astronomy accessible to people who spoke italian.

Kepler’s discoveries contribute to astronomy with the laws of planetary motion.

Kepler's law is based on the orbits of planets around the sun.

Kepler developed the Heliocentrism theory from previous scientists. Heliocentrism is a model in which the Earth and planets revolve around the Sun. Kepler

There are 3 laws issued by Kepler

the inner planet's orbit around the sun is based on an elliptical path and the sun is the center

Imaginary lines are drawn from planets to the sun cover the same area at the same time interval.

The square of the orbital period of a planet is proportional to the cube of its average distance to the sun

General formula:

The Sun has more gravity than the other plans in our solar system

using kepler's 3rd law

the Earth has more gravitation pull than the moon
