Question
Each item describes a characteristic that applies to one of the three planet-detection methods shown following. Match the items to the correct planet-finding method. used for most of the first 200 extrasolar planet detections allows for the extrasolar planet's radius to be determined planet-detection strategy of NASA's Kepler Mission this method was first to identify Earth-sized extrasolar planets currently best-suited to find Jupiter-sized extrasolar planets orbiting close to their stars can potentially detect planets in only a few percent of all planetary systems measures precise changes in a star's position in the sky in fractions of arcseconds looks for very slight, periodic dimming of a star Doppler method transit method astrometric methodExplanation / Answer
used for most of the first 200 extrasolar planet detections - Doppler method
allows for the extrasolar planet's radius to be determined - transit method (the radius can be calculated from the size of the planet captured while it transits the star)
planet-detection strategy of NASA's Kepler mission - transit method
this method was first to identify Earth-sized extrasolar planets - transit method (detected by NASA's Kepler)
currently best-suited to find Jupitar-sized extrasolar planets orbiting close to their stars - Doppler method (Recent observations of the transit method show promising results in hunting even super sized planets. However, Doppler method still remains the best to look for Jupitar-sized planets orbiting close to their stars.)
can potentially detect planets in only a few percent of all planetary systems - transit method (Here, the planet must pass directly between it's star and the Earth. But, for most extrasolar planets this seldom happens)
measures precise changes in a star's position in the sky, in fractions of arcseconds - astrometric method
looks for very slight, periodic diming of a star - transit method
