Kepler’s Three Laws that everything orbits the sun. The first law is that everything orbits the sun, all the planets orbit in the ecliptic of the sun which clear up a lot of the problems with the tycho model in retrograde motion. Ellipses.
The second law is equal areas in equal times. Equal Areas.
And the third law is the mathematical relationship equating distance from the sun, average distance from the planet to the sun, to the amount of time it takes that planet to travel around the sun. Periods. These are all necessary because it helps determine how far away we are, and how far away it is.
2. What are Newton’s 3 Laws. Explain each law in detail and why it is important in astronomy. (3 pts)
Newton’s first law is Inertia basically things keep doing what they are doing until acted upon by outside force. Like if a ball is moving it will keep moving until something stops it or if a person throws a Frisbee in the air it will still spin and fly until it gets caught by someone or something intercepts.
His second is acceleration to get acceleration you first must apply force to the object and to the mass of the object impedes that force.
And his third law is action and reaction for every action there is an equal and opposite reaction.

How would the weight of an astronaut on the Moon compare to her weight on Earth? Explain. The weight of an astronaut on the moon compared to her weight on earth would differ because on the moon it is gravity and gravitational pull. When she is on the moon to have a somewhat equal footing having heavy objects around on her and with heavy equipment would weigh her down making it able to walk where gravity reigns. On earth gravity is different because it is cause and reaction, and also the what goes up must come down. There isn’t anything she would need because gravity is already balanced and normal in a way on
