    Differentiate between Stars and planets

    Name the star having a system of planets with life on one of its planets.

    Suppose a light planet is revolving around a heavy star in a circular orbit of radius r and period of revolution T. The gravitational force of attraction between the star and the planet is proportional to (1)/(r^(3//2)) . Derive the relation between T and r.

    A planet of mass m rotates around a star of mass M. The time period of revolution is T, while the average distance of the planet from the star is a. It is known that there exists a relationship between them: find it. Assume the dimensional expression for G.

    Imagine a light planet revolving around a vary massive star in a circular orbit of radius R with a period of revolution T. if the gravitational force of attraction between planet and star is proportional to R^(-5//2) , then T^(2) is proportional to
