What astronomical observations did he make?

Hewas able to observe the phases of Venus, spots on the sun, mountains and craters on the moon, and the four largest moons of Jupiter.

What was three innovations is Newton known for?

His three laws of motion, universal gravitation and development of calculus.

Isaac Newton

Who was one of the most influential scientist in history, the crowning axcievment of the revolution? 1643-1727

Johann Kepler

A German scientist and mathematician who lived from 1571-1630

Nicholas Copernicus
