Transits of multiple planet systems can be analyzed to infer planetary masses.

Question

Quizplus · Accepted Answer

Transits occur when a planet passes in front of its host star, causing a small dip in the star's brightness. By analyzing the characteristics of these transits, such as the duration and depth, and combining them with radial velocity measurements of the star, scientists can infer the masses of the planets in the system. This technique has been used successfully for many multiple planet systems discovered by NASA's Kepler mission and other exoplanet surveys.
