Question

Quizplus · Accepted Answer

The Kepler mission is designed to detect exoplanets by observing transits, where a planet passes in front of its host star from our perspective, causing a slight, periodic dimming in the star's brightness. This method does not involve imaging planets directly, measuring Doppler shifts, or detecting stellar motion in the sky.
