We knew they had to be there. Once people realized that the sun is a star and that the planets travel around it, it was only

Science presents an overview of planet-hunting techniques and representative efforts for the nearly 900 confirmed exoplanets and
the hundreds of fresh candidates that are turning up every month.
The A to Z of exoplanets.
Measurements of the properties of extrasolar planets show that planetary systems are abundant yet diverse in their masses,
sizes, and orbital architectures.
Because exoplanets are so diverse, exoplanetary habitabity needs to be considered on a case-by-case basis.
