"My God, it's full of planets!" - Kepler hints at over 250 new potentially habitable worlds

9. Hot zone planets

are nearer to the star and have a smaller orbit/shorter period. This makes them more likely to be caught in a transit observation (the planet moving across the face of its star). For example, from the viewpoint of a nearby star, Earth would transit the Sun once a year, but Saturn would transit it only once every 30 years. Additionally, if the plane the planets are in is tilted from our perspectives, planets farther out might never transit while close in ones could clip the top or bottom of the star and be observable, even if not transiting fully.
