As of this writing there are 1,776 known exoplanets. They are distributed in 1082 planetary systems. In this video, all of the exoplanetary systems are presented to scale, in a simulated flyby.

Exoplanet discovery has become so commonplace that we only talk about new discoveries if they are Earth-like or potentially habitable.
In many ways we’ve become a victim of our own success. We’re constantly discovering entirely new planets, and the attitude tends to be “Ho, hum. Another one. Add it to the list…”
