The Kepler and CoRoT missions use which technique to detect planet candidates?
A)radial velocity measurements
B)direct imaging
C)measurements of transverse motion
D)planetary transits

Question

Quizplus · Accepted Answer

Both the Kepler and CoRoT missions use the transit method to detect planet candidates. This involves measuring the slight decrease in brightness of a star as a planet passes in front of it, causing a small dip in the light curve. This method allows for the detection of planets that are too small to be detected by radial velocity measurements or direct imaging. Therefore, option D, planetary transits, is the correct choice. The Kepler and CoRoT missions utilize the transit method to detect exoplanet candidates. This method involves observing a star over time for periodic dips in brightness caused by a planet passing in front of it.
