PLEASE HELP! I have a low fever and I am too sick to do anything so can anyone help me please answer these questions? 1: Why were Tycho and Kepler a good team?
2: How did changing the shape of the planet orbits help Kepler explain planetary movement?
3: What is an ellipse?
4: Does Kepler’s 2nd Law of Planetary Motion apply to satellites? Why or why not?

Thank you for helping me! you saved my life and my grade. :)
