The planet orbiting this star has been detected by both the transit and Doppler techniques, so we can calculate its density and get an idea of what kind of planet it is. Using the method of Mathematical Insight Finding Sizes of Extrasolar Planets, calculate the radius of the transiting planet. The planetary transits block 2 % of the star's light. The star TrES-1 has a radius of about 85 % of our Sun's radius.
