A New Year of New Exoplanet Data
We're kicking off 2026 with seven new planets, one demotion, one spectrum, and a gaggle of parameters that were submitted using our new template, now available through the Published Data Upload service!
The new planets are HD 128717 b, V2376 Ori b, TOI-5489 b & c, TOI-5716 b, TOI-5728 b, and TOI-5736 b. There are also new parameters for HD 143811 b, HAT-P-5 b, HAT-P-8 b, HAT-P-13 b, HAT-P-15 b, HAT-P-16 b, HAT-P-17 b, HAT-P-21 b, HAT-P-26 b, HAT-P-29 b, KELT-16 b, TIC 118798035 b, c & d, WASP-4 b, WASP-19 b, WASP-21 b, WASP-44 b, WASP-52 b, and WASP-103 b.

Kepler-1658 b's disposition had been updated to False Positive Planet (FPP) based on a published refutation. FPP data are removed from the Planetary Systems and Planetary Systems Composite Parameters tables, but are still available on the System Overview pages.
We've also added a new HD 143811 b spectrum taken by the Gemini Planet Imager (GPI) to the Atmospheric Spectroscopy Table.
