Multiple choice

What is the main controversy surrounding the method of detecting exoplanets?

  1. Whether or not the transit method is more accurate than the radial velocity method.

  2. Whether or not the microlensing method is more accurate than the direct imaging method.

  3. Whether or not the astrometry method is more accurate than the pulsar timing method.

  4. Whether or not the gravitational microlensing method is more accurate than the occultation method.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The main controversy surrounding the method of detecting exoplanets is whether or not the transit method is more accurate than the radial velocity method. The transit method is more sensitive than the radial velocity method, but it can only be used to detect exoplanets that are transiting their host stars. The radial velocity method is less sensitive than the transit method, but it can be used to detect exoplanets that are not transiting their host stars.
