Question

Quizplus · Accepted Answer

GAIA is the space mission that is mainly searching for extrasolar planets using the astrometric method. This method involves measuring the tiny wobbling motion of a star caused by the gravitational pull of an orbiting planet. GAIA uses a high-precision astrometric instrument to detect these wobbles and thus identify potential exoplanet candidates. Kepler, CoRoT, and Spitzer, on the other hand, primarily use the transit and radial velocity methods to detect exoplanets.
