Astronomers discover an exoplanet, a planet orbiting a star other than the Sun, that has an orbital period of 2.25 Earth years in a circular orbit around its star, which has a measured mass of 3.80×1030 kg. a) What is the radius of the orbit in meters? b) If the exoplanet has a mass of 6.100x10 24kg and a radius of 6520km, what will be the acceleration due to gravity on the surface of the exoplanet?
