6. WARM UP: Period 1,3,4-6 There is three planet solar system (planet Beta, Delta and Gamma, planets orbiting a 2 solar mass star. Planet Gamma is 6 AU, Planet Delta is 3 AU and the last planet’s distance (Beta) is unknown but its orbital period is 0.5 Earth years long. What is planet G and D’s period, what is Planet B’s distance for its parent star? If the sun tripled its mass how would it change the periods and/or distances. BTW why is there no Alpha Planet? Period 2 What are epicycles? What did they help explain?
