10 Amazing Exoplanet Discoveries | Space

There are several ways that exoplanet discoveries are made. The most obvious way to find an exoplanet is to see it directly using a telescope. This isn’t as easy as it sounds, because distant planets are so faint they are usually lost in the bright glare of their host stars. Nevertheless, this approach has been successful in some cases.

The majority of exoplanets have been found by transit, which involves looking for a slight dimming of the host star as the planet passes in front of it. However, this can only be used if the geometry of the planet’s orbit allows us to see the transit from Earth.
