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. Doppler Method: |
Doppler Method: 1. Used for the most of the first 200 extrasolar planet detections 2. Currently best suited to find Jupiter sized extrasolar planets orbiting close to their stars |
|
Transit Method: |
1. Planet detection strategy of NASA's Kepler Mission 2. Looks for very slight, periodic dimming of a star 3. Allows for the extrasolar planets radius to be determined 4. Can potentially detect planets in only a few percent of all planetary systems 5. this method was first to identify Earth-sized extrasolar planets |

Astrometric Method: |
1. Measures precise changes in a stars position in the sky in fractions of arc seconds |
