Astronomers are constantly discovering new planets orbiting nearby stars. In the following scenario, compare the gravitational force between the planet and its star to the gravitational force between the Earth and the Sun and enter your result as a decimal with no units. (For instance, if the gravitational force between the planet and the star is 1/4 the gravitational force between the Earth and the Sun, enter 0.250)

A planet that has a mass 7.93 times that of the Earth is orbiting a star that has the a mass 2.98 times that of our Sun. The planet orbits at an average distance 1.25 times greater than the average distance between the Earth and the Sun. How does the gravitational force between this planet and its star compare to the force between the Sun and the Earth?
