Proves the earth is a sphere
-
Calculated Distance between earth and the moon, made the star catalog, made a scale to say how bright the stars are
-
Made a geocentric model, an earth centered model, was wrong
-
Mathematician and astronomer, proposed the earth revolved around the sun
-
Made a recording from what he saw for 20 years, made his own model and where very accurate, in which the planets around the sun, and the sun revolved around the earth
-
Born in Italy, he made his own telescope, saw craters,valleys, and mountains on the moon, mapped starts and keep accurate recordings of sunspot activity and the phases of Venus.

Student of Tycho, made the three laws of planetary motion, one called elliptical orbit.
-
The refracting telescope telescope that uses a lens as its objective to form an image.

Made universal gravitation, many theories used this law, as well as this he used math to prove his laws. Newton showed that the laws governing astronomical bodies were the same laws governing motion on the surface of the Earth.

The reflecting telescope uses a single or combination of curved mirrors that reflect light and form an image.

In 1981, this was the first space shuttle, it launched like a rocket, but landed like an airplane
-
In 1996, a rover was launched to probe mars, and in 1997 it landed.
-
The Cassini orbiter was a probe sent to Saturn to take in depth pictures and study the rings and the system. It was named this because an Astronomer named Giovanni Cassini was studying Saturn
