Exoplanets – How Do We Find Them?
Exoplanets are planets that do not orbit our Sun. Note that they do not have to orbit other stars, because as we will see later, we have also discovered “rogue” exoplanets that are alone in space. As of August 2020, 4301 confirmed exoplanets have been discovered, with another 2120 suspected exoplanets awaiting further confirmation data.
