Question

Quizplus · Accepted Answer

Moons of exoplanets, also known as exomoons, can be detected through their effects on the duration of exoplanet transits. When an exoplanet with a moon passes in front of its host star from our point of view, the moon can cause deviations in the timing and duration of the planet's transit across the star. This can provide indirect evidence of the moon's presence.
