NASA Exoplanet Archive - 5,788 Confirmed Planets (data snapshot 2026-03-22)
Every dot is a confirmed planet orbiting another star. As of this snapshot, we've found 5,788 of them with measured masses and orbits.
The big cluster in the upper left? Those are hot Jupiters - gas giants orbiting closer to their star than Mercury does to ours. We've found so many not because they're common, but because they're the easiest to detect: big planets making big wobbles on short timers.
Try switching the x-axis to Planet Radius. You'll see planets stack at specific sizes - rocky worlds around 1-2 Earth radii, ice giants around 3-4 (think Neptune), and gas giants near Jupiter's size. Gas giants don't get much bigger than Jupiter no matter how massive they get. They just get denser. At about 80x Jupiter's mass, they ignite and become a star.
The gaps in the plot aren't empty space - they're the limits of our instruments. Most of the planets we can't see yet live right where the gaps are.
