To date, more than 4,000 exoplanets have been discovered and are considered "confirmed." However, there are thousands of other "candidate" exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.

How are most extrasolar planets discovered?
Most exoplanets are found through indirect methods: measuring the dimming of a star that happens to have a planet pass in front of it, called the transit method, or monitoring the spectrum of a star for the tell-tale signs of a planet pulling on its star and causing its light to subtly Doppler shift.

How many exoplanets are habitable?
A potentially habitable exoplanet is a hypothetical type of planet that has liquid water and may support life. As of March 2020, a total of 55 potentially habitable exoplanets have been found. Of those, one is believed to be Sub-terran (Mars-size), 20 Terran (Earth-size) and 34 Super Terran (Super Earths).
How many exoplanets are confirmed and unconfirmed?
To date, more than 4,000 exoplanets have been discovered and are considered "confirmed." However, there are thousands of other "candidate" exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.
