Homework Statement
Astronomers discover a new transiting planet named Jakku. The parent star, Abrams, is known to have a radius equal to ½ that of the Sun’s. a) The transit depth of Jakku is 757 parts per million (757 x 10-6). How large is the planet? Convert your answer into units of Earth radii. b) The blackbody temperature of Jakku is 290K. The scientists who discovered it make a press release claiming this planet is definitely habitable. What criticism might you have of this statement? [/B]
Homework Equations
transit depth = (Rp/R*)2sq
The Attempt at a Solution
[/B]
since I already have the transit depth 757 x 10-6 =(Rp/216237)2sq
I know I have to solve for Rp...but this is where I need help
