-
Radial Velocity Method
-
Microlensing
B
Correct answer
Explanation
The transit method involves observing a star as an exoplanet passes in front of it, causing a slight dimming of the star's light.
How does the radial velocity method detect exoplanets?
-
By measuring the Doppler shift of the host star's light
