Question

how did keplers 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.

Explanation:

Kepler formulated three laws of planetary motion that describe the motion of planets around the Sun. These laws were fundamental in the development of astronomy. While his work supported the heliocentric model, its most significant contribution was establishing the laws of planetary motion. The rising and setting of the Sun is related to Earth's rotation, not Kepler's discoveries. And there is no connection between his discoveries and making astronomy accessible to Italian - speakers.

Answer:

They established the laws of planetary motion.
