Document Summary
Assignment 2: based on todays lecture, 3 data sets and you chooses two to analyze. When you want to take a photo of another planet you have to look directly at the star. This exisits when there are 2 bodies of mass. Technically the center of mass is at the focus: the semi major axis- half fo the major axisis (a, eccentricity is the amount that the ciricle is streched. Eccentricity is c/a: c is the distance from the enter to the focus, eccentricity of 0 menat it"s a circle, the sun/ star is at the center of the circle but not at the center of the. If p3 gets bigger a3 get bigger: kepler"s third law means that the father a way form a star the planet is the longer it takes to complete and orbit. Transit method for detecting exoplanets: conceptually straight forward, transit- eclipse (a thing is passing in front of another thing)
