How do you find an exoplanet?

The video tutorial explains the challenges of directly observing planets and how astronomers use the gravitational influence of planets on stars to detect them. It describes the process of measuring the star's wobble and mapping its orbit to infer the presence of planets. The video also addresses skepticism about early planet detections and explains the transit method, where a planet crossing a star's disk causes a measurable dimming of starlight. This method was validated in 1999 when astronomers successfully predicted and observed a planet transit.
