Copernicus is a polish astronomer and thought Ptolemy's model of the solar system was too complicated.
What is Copernicus lifetime job and what did he think about Ptolemy's wheels-on-wheels model?

Kepler learned after observing planetary motion that planets motion to not be exactly circular. Instead he found ellipse.
What did Kepler learn when observing the planets?

Aristotle thought Earth was the center of all things.
What is the thing Aristotle thought about Earth and the solar system?

Aristarchus was proposed to have made a heliocentric model of the solar system. Heliocentric is a model of Earth and the other planets orbiting the sun.
What is the model that Aristarchus was proposed to have created?
200
Ptolemy made a book called the "Almagest". It was based on observations of the planets going back a much as 800 years.
What is the book Ptolemy made and what was it based on?
200
Copernicus created the first detailed heliocentric model of the solar system.
What is the model that Copernicus created?

Kepler's first law states that planetary orbits are ellipses with the sun at one focus. Kepler's second law states that planets move faster in their when closer to the sun. Finally, Kepler's third law relates the distance of a planet from the sun to the time it takes to go once around its orbit.
What is Kepler's three laws.

Aristotle made a geocentric model of the solar system. Geocentric is a series of the moon, sun, planets, and stars circling Earth.
What is the model Aristotle made of the solar system?
300
Aristarchus to measure the relative distances of the moon and sun.
What is the thing Aristarchus attempted to measure?
300
Ptolemy developed a geocentric model that was used by astronomers for the next 14 centuries.
What is the model Ptolemy created and how long was it used by astronomers?
300
Copernicus adopted the idea that planetary paths should be perfect circles, and used the wheels-on-wheels system.
What was the ideas Copernicus adopted from Ptolemy?

Galileo created a way to approach questions and today we call that scientific methods.
What is the method Galileo created to approach questions?

Aristotle thought that if the Earth went around the sun than the relative positions of the stars would change.
What is the thing Aristotle thought if Earth went around the sun?

When Aristarchus attempted to measure the relative distances of the moon and sun it was a major contribution to science.
When Aristarchus attempted to measures the relative distance of the sun and moon did it contribute to science?

Ptolemy believed that a celestial body traveled at a constant speed in a constant circle. In Ptolemy's model, the planets moved on small circles that turned into large circles. This wheels-on-wheels fit observation better than any model that had come before.
What is the thing Ptolemy believed and what did he call this system?
400
Yes, Copernicus model fit a little better than Ptolemy"s geocentric model.
Was Copernicus heliocentric model a little better than Ptolemy's geocentric model?

Galileo used a powerful telescope that he created to observe Jupiter's moons which are; Io,Europa,Callisto, and Ganymede.
What is the thing that Galileo made that helped him view celestial objects and what did he view?

The apparent shift of an object when viewed from a different is called a parallax.
What is the apparent shift of an object when viewed from a different location called?

Even though Aristarchus ratio of distances were much to small it helped to solve a scientific problem with observation and geometry.
Did Aristarchus ratio of distances to the relative distances of the moon and sun help to solve a scientific problem with observation and geometry?
500
Yes, Ptolemy's observations of Earth's wheels-on-wheels prediction allowed prediction of planetary motion in the future.
Did Ptolemy's wheels-on-wheels system allow prediction of the motion of planets years in the future?
500
Yes, the heliocentric model of Copernicus is generally seen as the first step in the development of modern day models of the solar system.
Did the heliocentric model of Copernicus help develop a modern day model of the solar system?

Galileo observed that Venus went through phases just like our moon.These phases result from changes in the direction that sunlight strikes Venus as Venus orbits the sun.
