Question

Quizplus · Accepted Answer

The Kepler mission uses the transit method to detect exoplanets. This technique involves measuring the brightness of a star and looking for periodic dips in brightness that could be caused by a planet passing in front of it. This method is particularly effective for detecting exoplanets that are similar in size to Earth and orbiting close to their host stars. The other techniques listed (Doppler, astrometry, and gravitational lensing) are also used to detect exoplanets but are not the primary method used by the Kepler mission.
