Marks Question 24 (3 marks) Two planets X and Y travel anticlockwise in circular orbits about a star, as seen in the diagram. The radii of the orbits X and Y are in the ratio 2:5. The planets are shown below at a time interval of 5 years, Initially they were aligned, making a straight line with the star. Five years later, planet X has rotated through 120", as shown in the diagram. Initial position of planets Position of the planets 5 years later Planet Y Planet X \\Planet X Planet Y Determine how long it takes planet Y to orbit the star
