You are observing a star which has a normal measured flux of 24.0 photons per second. The brightness of the star shows regular dips - transits caused by a planet in an edge-on circular orbit. During each dip, the brightness of the star decreases by 0.07200000000000006 photons per second. Transits repeat every 5.2 days. If the star has a radius of 4.1 x 10 m, a mass of 1.6 x 10"kg and a luminosity of 1.3 x 1040W, what is the radius of the planet (in metres)? 26
