The Lucky 13

The archive has added 13 planets this week—many of them discoveries by NASA's TESS, and one planet from a survey that has us ready for Happy Hour. Say cheers to KOINTREAU-1 b!

The other new planets are GJ 3090 c, TOI-261.02, TOI-682.01, TOI-1054.01, TOI-1230.01, TOI-1774.01, TOI-1243 b, TOI-4529 b, TOI-5788 b & c, TOI-6716 b, and TOI-7384 b.

New Archive Demos Posted to YouTube

We've posted new videos to YouTube as part of our Tour of the NASA Exoplanet Archive series, which provides overviews of the archive's tools and data, along with tips for using the archive's offerings more effectively. Take a look at the first three offerings:

More videos will be added as new features and services are released, so make sure to subscribe to the NASA Exoplanet Archive channel.

Exoplanet Candidate HD 137010 b Added to the Archive

We've added a planet candidate to the HD 137010 System Overview page to help the community track this object with future follow-up observations. More information about this exciting discovery is in the NASA media release and the discovery paper.

The candidate, located 146 light-years away, was found in archival data from NASA's Kepler/K2 mission with a single transit in a 10-hour transit duration. It has an Earth radius and an unknown period that could range between about 300 and 550 days, placing it near the outer edge of the habitable zone of its K star, which is about 70% the size of our Sun.

The following data plot shows how HD 137010 b may occupy a region of orbital period and radius space similar to Earth's:

The Exoplanet Archive includes candidate exoplanets on System Overview pages when they are delivered by missions, such as TESS and Kepler, and we will also occasionally include candidate planets that are of significant interest to the community and public. Although HD 137010 b was assigned a planet letter, its status is currently not confirmed and it does not appear in the Planetary Systems and Planetary Systems Composite Data tables.

INCOMING: 468 New Spectra!

This week's release features a massive haul of new spectra: 468! This update increases the archive's spectral holdings by 43% and includes JWST data for PSR J2322-2650 b, a lemon-shaped exoplanet orbiting a pulsar that appears to have a new type of planet atmosphere. Read the NASA media release and the discovery paper for details. You can find all of this week's new spectra in the Atmospheric Spectroscopy Table.

We also have seven new planets this week: KMT-2022-BLG-1818L b & c, TOI-5422 b, TOI-5789 b, c, d, & e. Click on a planet name to go directly to its System Overview page, or browse the Planetary Systems and Planetary Systems Composite Data tables.

Nine New Planets, Including a "Super-Puff" Sub-Neptune

This week's update features TOI-4507 b, one of the longest-period and youngest "super-puff" planets confirmed to date. The other new planets are KMT-2024-BLG-1005L b, NGTS-34 b, NGTS-35 b, TOI-3288 b, TOI-4666 b, TOI-4940 b, TOI-5349 b, and TOI-7166 b.

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. Click on a planet name to go directly to its System Overview page, or browse the Planetary Systems and Planetary Systems Composite Data tables.

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.
