26 exoplanets found since 2020 sit in their stars' habitable zones — but only 10 have a measured radius

Asked:

Find every exoplanet discovered since 2020 in the habitable zone, and give me the host star, orbital period and radius and map them on the sky map

26 confirmed planets first reported from 2020 through the scan date of 1 September 2026 that a cited source explicitly places in, at the edge of, or as a candidate member of the circumstellar habitable zone. "Habitable zone" means orbital distance where liquid water is possible under some assumptions — not inhabited, and not necessarily habitable; definitions differ between sources. Periods are in days, radii in Earth radii; radial-velocity planets often have no measured radius, shown as an em dash.

What the map cannot say

The 2026 scan of Wikipedia's yearly discovery lists directly flags 14 planets as habitable-zone, from BD-11 4672 c (2020) to GJ 887 d (2026); the rest come from HZ catalogs and per-planet sources. en.wikipedia.org

Orbital periods span 8.5 days (LP 890-9 c, around a dim M6 dwarf) to 647.6 days (82 G. Eridani d, around a Sun-like star) — the habitable zone moves with the star's brightness. science.nasa.gov

Kepler-1649 c, an Earth-sized transit find from 2020 Kepler-archive reanalysis, is listed by a 2026 AI transit-search catalog as a conservative habitable-zone planet — the c planet, not the hotter inner b. arxiv.org

Aliases were merged before counting: GJ 1002 = Gliese 1002, LP 890-9c = SPECULOOS-2 c, HN Librae = HN Lib, and 82 G. Eridani d = HD 20794 d. en.wikipedia.org

Method: 26 confirmed exoplanets first reported 2020 – 2026-09-01 with an explicit habitable-zone statement in a cited source (Wikipedia yearly discovery lists, NASA science pages, NASA Exoplanet Archive, HZ catalog papers). Scan date 2026-09-01. Completeness is relative to explicit HZ labeling in accessible sources, not to any single accepted HZ boundary. Period in days, radius in Earth radii where measured (transits); mass-only radial-velocity planets show an em dash. Right ascension is available for 20 of 26 hosts and declination for 1 (GJ 251), so 20 hosts are drawn at their true RA, 19 of them on the celestial-equator line because their declination was not in the supplied rows; 6 hosts without coordinates are listed in the table only. A few automatically extracted values (mismatched periods, a wrong planet letter) were corrected to the yearly-list values.
