How to Find an Exoplanet

The video discusses the challenges of discovering exoplanets, especially those orbiting distant stars. Direct observation is limited to nearby stars with large planets. Most exoplanets are found indirectly by observing their effects on parent stars, such as dimming during transits or star wobble due to gravitational pull. These methods are effective for large planets close to stars. Advanced techniques have helped discover over 1800 exoplanets by 2014.
