Beyond the Solar System there are more than 3000 stellar systems composed of since dwarfs to supergiant stars, orbited by more than 4000 exoplanets divided in several types, small and rocky, giant and gaseous, some of which are not seen in the Solar System. Several methods are used in order to detect and confirm these worlds, each one with its own advantages. Successful space missions use some of them, aiming mainly to detect certain effects caused by exoplanets orbiting their systems’ stars. There are lone planets in small systems, in systems with more than one star, with several planets, or even orbiting different bodies. Like Earth, there are those within their stars’ habitable zone, region where water exists in its liquid form, what is usually related to possible life forms. In the same way as in the Solar System, there may be other objects than stars and planets, they are the exomoons, exocomets, asteroids and exorings, some of which are already confirmed, while others are still candidates. Detecting and confirming objects that were never seen before is a difficult and delicate task, but with advanced technology in the near future there will be more precise equipments able to characterize systems and bodies which are unable to be observed nowadays. This work aims to clarify frequent terms and concepts regarding exoplanetary systems, present important data and a few examples of exoplanets and extrasolar objects.
