Sue is on planet X which is a distance 6.6x109 km from a certain star which has a radius 7000 km. Sue measures the maximum intensity of light on the surface of the planet to be 9000 W m2. Planet X has no atmosphere and so there is no absorption of light between the star and the surface of the planet. Calculate the temperature of the star, which can be assumed to be a black body. a. 6.1e5K O b. 5.78 K O c. 2.0e5K O d. 6.0e6 K e. 6.0e8 K
