Contribution to orbital motion theory
Believed that the planets and the Sun orbited Earth. He saw no sign that the Earth was in motion. This meant that the Earth had to be stationary, and the planets, the Sun, and the fixed dome of stars rotated around Earth.
Reasonable criticism of the theory
In his time period how would he know any different? On earth it is impossible to tell, and all you can see is the stars and sun moving across the sky day in and day out, so at the time his theory was good. Now with all the technology we have we now know he was wrong, but his theory was widely accepted for a long long time.

Conclusion
1. Explain why is the study of orbital mechanics so controversial?
Orbital mechanics is a modern version of celestial mechanics which is the study of the motions of natural celestial bodies such as the moon and planets. It is controversial, more in the past, because the technology wasn't very good so it was mainly based on multiple peoples theories. So most people disagreed with each other until greater technology was invented.
2. What factors contribute to a theory gaining mass acceptance?
The more people that approve of your theory, the more people that will jump onto the bandwagon. Also if you have more scientific evidence people will believe you more.
3. What impacts did each of the following contributors make on the evolution of orbital mechanics?
A. Nicolaus Copernicus: In 1515 Nicolaus Copernicus proposed that the Earth was a planet like Venus or Saturn, and that all planets circled the Sun.
B. Tycho Brahe: Brahe believed in a model of the Universe with the Sun orbiting the Earth but the other planets orbiting the Sun.
C. Johannes Kepler: Made 3 Laws
- The orbit of a planet is an ellipse with the Sun at one of the two foci.
- A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.
- The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
D. Robert Hooke: Planets motion is determined by compounding its tangential velocity with the change in radial velocity impressed by the gravitational attraction of the Sun
E. Sir Isaac Newton: realized that the force by which an apple falls from a tree to the ground is the same one that makes planets fall around the sun. Newton also concluded such a planetary orbit should be elliptical

(Narrator) This Historical figure is Aristotle, He was born 384 BCE. He was a student at Plato’s academy, graduated early and was allowed to teach there shortly after. He tutored Alexander the Great, and eventually settled down with a woman named Pythias, had a son and a daughter, Nicomachus and Pythias.
(Critic) How could you possibly think that everything revolves around Earth?
(Aristotle) It’s simple, we are motionless, the stars, moon, and sun all streak across the sky, so they must be revolving around us. There is no other evidence to contest this.
(Moderator) During Aristotle’s time there was no way to tell, by just using the naked eye and no further technology this theory was acceptable because it made logical sense, if you didn’t seem to be moving, and things were moving around you, what would make you think you were in motion?
