-
He is known for the Cassini laws which is the motion of the moon.He is the first person to discover the division of Saturns rings.
-
Sir Isaac Newton formulated forces. He formulated gravity and discovered laws of motion. Newton came up with the design for a reflecting telescope in 1668

William Herschel discovered Uranus. He had the idea that nebulae were composed of stars.
-
He founded the Lowell Observatory in Flagstaff Arizona. He discovered Pluto in the observatory.
-
He classified stars by their absolute brightness and color. He made the Hertzsprung-Russell Diagram
-
He showed how mass and energy were equivalent. He link for dimensional gravitational with the orbits of the planets. He made the formula E=mc2 which is atomic power in an atomic bomb.
-
Know as one of the most important astronomer of all time. He discovered our Milky Way and more galaxies. He found that the speed and galaxies distance are related.
