Answer to Question #195706 in Astronomy | Astrophysics for Pranali Patil

Question

To date, we have discovered 4375 exoplanets (planets that are orbiting a star other than our Sun) and of these, there are 3247 different exoplanet systems.  Of these systems, there are 11 that have at least six planets. Choose one of these systems (not our solar system) and for that system, randomly select four planets.  For each of these planets, record (or calculate) the mean orbital radius and orbital period (in units of your choosing).  Then use this information to calculate the Kepler ratio for each of these planets orbiting its star.  Compare the ratios and determine whether or not Kepler’s third law applies for exoplanets around their star other than Earth.
