What is the primary detection method used by the radial velocity method?

  1. Doppler shift

  2. Photometry

  3. Microlensing

  4. Astrometry
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The radial velocity method detects exoplanets by measuring the Doppler shift in the light of the host star caused by the gravitational pull of the exoplanet.

Multiple choice
