A extrasolar system of planets consists of a star (mass 5.0 x10³⁰ kg) and two planets. The first planet has a mass of 3.0 x 10²⁴ kg and the second planet has a mass of 3.7 x 10²³ kg. At one point in time the system is arranged in a right triangle that has the two planets located at the ends of the hypotenuse. The distance from the star to the first planet is 6.7 x 10¹⁰ m and the distance from the star to the second planet is 6.8 x 10¹² m. What is the gravitational potential energy of the system when it is in this alignment?
