3 simple methods Exoplanets can be detected beyond our solar system.
I will try to make it as comprehensible as possible.
1. Transit-A stars luminosity dims slightly due to the object that passes by.
2. Radial velocity- A stars position moves (wobbles) continuously due to the gravitational attraction of other planetary bodies orbiting it.
3. Coronagraph telescopic attachment and infrared.-A telescopic attachment which allows for a Stars luminosity to be artificially blocked, and allows for other objects in the vicinity to be infrared, and observable.
You can no longer use the lame argument "We're special because our planet is the correct distance from the star". :-)
