Using Flat Data to pull live-updated data from the NASA Exoplanet Archive. As of September 10, 2021, it includes 4,516 planets discovered outside of our solar system. There are 53 known planets orbiting 3-sun systems, like Liu Cixin's Trisolarans, and 2 planets orbiting 4-sun systems: PH1 b and 30 Ari B b.
