Explanation:

• Johannes Kepler: Kepler formulated the three laws of planetary motion. These laws describe the motion of planets around the Sun. The first law states that planets move in elliptical orbits with the Sun at one focus. The second law (the law of equal areas) implies that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The third law (the harmonic law) relates the orbital period of a planet to its semi - major axis.
• Galileo Galilei: Galileo made significant improvements to the telescope. With his improved telescope, he was the first to observe the craters on the Moon, which provided evidence against the Aristotelian view that celestial bodies were perfect and unblemished.

Answer:

• Proposed the 3 major laws of planetary motion: Johannes Kepler
• Invented an improved telescope and was the first to view the craters of the moon: Galileo Galilei
