To view only the most recently added planets and updated parameters (default and non-default), see this pre-filtered and pre-sorted interactive table.

Note to our users: The link format on this page allows you to easily access overview pages for both planet hosts and their planets. Clicking on either the host name or the planet letter takes you to the object's respective overview page.

Countdown to 4,000 Planets! We're only 84 confirmed planets away from reaching 4,000 in the archive! To celebrate this next milestone, we're having a contest!

Show or tell us in your own words or images what YOU think the 4000th planet could look like. Would it be a puffy hot Jupiter in a binary system? Or a rocky super-Earth in a multi-planet system? Or perhaps it's a world made entirely of water or ice?

This contest is open to all ages, and entries can be anything from a crayon drawing to a haiku. Get creative!

To enter, publicly tweet to us at @NASAExoArchive or post on our Facebook page with a link to your entry. You must include the #Exoplanet4K hashtag to be entered in the random drawing. The winner, randomly drawn from all entries, will receive a full-color print of the 55 Cancri e poster from the Exoplanet Travel Bureau.

Have fun and good luck!

New Data This Week: We've added HATS-70 b, GJ 143 b, HD 23472 b & c to the archive, as well as new planet parameter sets for X0-2 N b. These data can be found in the Confirmed Planets, Composite Planet Data, and Extended Planet Data tables.

There are also new transmission spectra for X0-2 N b and XO-1 b, and new microlensing solutions for MOA-2008-BLG-310L b and MOA-2009-BLG-319L b.

21 Confirmed Planets Added: Several previously removed planets were added back to the archive this week based on radial velocity data published in Udry et al. 2018, as well as some new planets from the same paper. There is another planet, K2-292 b (a.k.a. HD 119130 b) from Luque et al. 2018, new planet parameter sets for K2-264 b & c and HD 20782 b, and new transmission spectroscopy for XO-2 N b.

The full list of planets from the Udry paper are: HD 20003 b & c, HD 20781 b, c, d & e, HD 21693 b & c, HD 31527 b, c & d, HD 45184 b & c, HD 51608 b & c, HD 134060 b & c, and HD 136352 b, c, & d. The reinstated planets are listed on the Removed Targets page.

The new planet and stellar data can be accessed from the Confirmed Planets, Composite Planet Data, and Extended Planet Data tables.

This week we added K2-289 b and the third confirmed TESS planet, HD 202772 A b. View their data in the Confirmed Planets, Composite Planet Data, and Extended Planet Data tables.

We also removed HD 73256 b based on a published refutation. Note: For a comprehensive list of all targets removed or excluded from the archive, see the Removed Targets page. For more information about the archive's criteria for classifying and including objects, see our Exoplanet Criteria page.

Five New Planets: We've added five new planets this week, including LHS 3844 b, the second confirmed planet discovered by the Transiting Exoplanet Survey Satellite (TESS) mission. The other four planets are: K2-290 b & c, K2-291 b, and GJ 4276 b. View their data in the Confirmed Planets, Composite Planet Data, and Extended Planet Data tables.

UKIRT DR3 Microlensing Survey Data: We've added almost 26 million light curves from the 2018 United Kingdom InfraRed Telescope (UKIRT) Microlensing Survey, which tips the total number of light curves in the archive above 100 million! Other data sets served include Kepler, K2, KELT, SuperWASP, CoRoT, and others. See our Holdings page for details.

You may access the UKIRT DR3 data, as well as previous UKIRT releases, from the UKIRT Bulk Download page. Or, use the UKIRT search interface to find a subset of data and browse them in an interactive table (enter 2018 for Survey Year to view DR3 data). Read the documentation for more information.

Many thanks to the UKIRT Microlensing Team for providing these data to our users.

There have been 11 transiting and two radial velocity planets added to the archive this week. They are: Kepler-730 c, HD 202696 b & c, HATS-60 b, HATS-61 b, HATS-62 b, HATS-63 b, HATS-64 b, HATS-65 b, HATS-66 b, HATS-67 b, HATS-68 b, and HATS-69 b.

View their data in the Confirmed Planets, Composite Planet Data, and Extended Planet Data tables.

The first planets to be added in 2019 are three single, transiting K2 planets, one of which (K2-288 B b) was found by citizen scientists using Exoplanet Explorers! The other two planets are K2-286 b and K2-287 b. See the press briefing for K2-288 B b, and read the discovery paper.
