The Transit Method of Discovering Exoplanets
41:47 - 46:28 (04:40)
The transit method is used by astronomers to discover exoplanets, which involves observing a star for small dips in brightness that could indicate the presence of a planet passing in front of it, and the success rate is around 1% of stars observed in a particular field.

Summary
The transit method involves detecting planets by observing the dimming of starlight as a planet crosses in front of its host star along our line of sight. Only about 1% of planetary systems are oriented in this way, which limits the number of planets we can detect using this method.
