How do we find exoplanets?
Exoplanets are planets outside of our solar system that orbit other stars. These planets are usually detected by astronomers using various methods and techniques.
Transit Method
The transit method is the most widely used technique to discover exoplanets. It involves measuring the dimming of a star's light as an exoplanet passes in front of it. The amount of dimming provides information on the exoplanet's size and orbit.
Radial Velocity Method
The radial velocity method, also known as the Doppler method, measures the wobble of a star caused by the gravitational pull of an orbiting exoplanet. This method can provide information on the exoplanet's mass and orbit.
Direct Imaging
Direct imaging is the method of capturing images of exoplanets by observing their light. This method is challenging because exoplanets are much dimmer than the stars they orbit. However, direct imaging can provide valuable information on exoplanet atmospheres and compositions.
Other Techniques
Other techniques used to discover exoplanets include gravitational microlensing, astrometry, and pulsar timing.
