How many exoplanets are there?
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.

I’ve never trusted these numbers, or the process used to get them. It requires the planets and stars be PERFECTLY aligned with earth, so that we can detect the shadow.
