3 3) What happens to the period as the star-planet distance increases? Why do you think there is a relationship? 4) Astrononlers believe that terrestrial planets in binary star system could not support advanced life. (hint: Dole (1964) estimated that the average amount of energy received by a planet not could vary by more than 10 % without affecting its habitability). Reset the Simulation (yellow button at lower right) Select "Binary Star, planet", record the initial conditions in the simulation's 'data table below (masses, distances, and velocities for the yellow star, pink planet, and blue planet). Select "Path", "Center of Mass", and "Grid". Run simulation for a few minutes (real time). Think about what occurred in the simulation and what changes might be made to try to make a stable system. In particular, try to create a stable system in which the planet would receive a fairly constant amount of energy from the starts). Create a computer simulation that you believe meets the criteria mentioned above. Run your simulation to test. Carefully describe the initial conditions of the simulation in your attempt(s), your observations, and conclusions that support or refute this hypothesis. (Note that light follows an inverse square law just as gravity does. The amount of light received from a star falls off as 1 / (distance).) SUS OI
