Scientists in early Astronomy

Who was the scientist that Developed the three laws of planetary motion and came up with the equation of P² = a^3.

• Aristarchus

• Johannes Kepler

• Copernicus

• Tycho Brahe

Who was a major advocate of the Geocentric Theory with evidence supporting a spherical Earth (used shadows in wells)

• Galileo Galilei

• Erotosthenes

• Aristotle

• Johannes Lippershey

Who devised ways to illustrate the geocentric theory with complex system of spheres and epicycles

• Ptolemy and Euduxus

• Isaac Newton

• Aristarchus

• Pythagoras

The man attributed to the heliocentric theory because he was the first to publicly support it (on his death bed)

• Isaac Newton

• Johannes Kepler

• Galileo Galilei

• Nicholas Copernicus

This man observed sunspots, phases of Venus, moons of Jupiter. People believed that he invented the telescope (he did NOT), and was put under house arrest for 9 years.

• Nicholas Copernicus

• Johannes Lippershey

• Galileo Galilei

• Ptolemy and Euduxus

This man invented the telescope.

• Johannes Lippershey

• Johannes Kepler

• Isaac Newton

• Pythagoras

Compiled huge amounts of data that eventually led Kepler to his laws of motion. He lost his nose in a duel and died of a bladder infection.

• Erotosthenes

• Aristarchus

Devised a way to measure the circumference of the Earth at 25,000 miles

• Eratosthenes

• Aristotle

• Pythagoras

• Aristarchus

Is attributed to a well known math theorem (a² + b² = c²) and supported a round earth theory but had no evidence

• Aristotle

• Copernicus

• Pythagoras

• Erotosthenes

Devised the Laws of Motion that helped explained Kepler's Planetary Laws of Motion

• Tycho Brahe
