Question

Quizplus · Accepted Answer

The most common method for detecting exoplanets is the radial velocity method, which measures the periodic Doppler shift in the star's spectrum caused by the gravitational pull of the planet. The amount and frequency of the star's motion are directly related to the mass of the planet and its distance from the star. Closer planets have a stronger gravitational pull on the star and cause it to wobble more, making them easier to detect.
