An exoplanet discovered through the transit photometry method is unlikely to also be detectable with what other method of detecting exoplanets?
A) astrometric method
B) radial velocity method
C) variable transit timing method
D) phase cycle brightness method

Question

Quizplus · Accepted Answer

The astrometric method relies on detecting the tiny wobbles in a star's position caused by the gravitational pull of an orbiting planet, which is independent of the transit photometry method that detects planets by observing the dimming of a star as a planet passes in front of it. The other methods listed (B, C, D) can complement or be related to observations made through transit photometry.
