59 planets since 2020 sit in or at a habitable zone — from sub-Earths to 10-Earth-radius giants
Asked:
“Find every exoplanet discovered since 2020 in the habitable zone, and give me the host star, orbital period and radius.”
A broad catalog of 59 confirmed exoplanets with discovery or confirmation years 2020–2025 that a current habitable-exoplanet compilation, NASA announcement, archive news page, or discovery paper places in or at a habitable zone. Orbital periods run from about 10 to 2,164 Earth days and radii from 0.8 to 10.2 Earth radii; blanks mean no reliable value was resolved.
Orbital period vs radius, log–log
23 planets with both a period and a radius; 36 rows lack one value and are omitted here (they remain in the table). Colour = discovery year. A diamond marks a planet whose habitable-zone wording is explicit in its own source; circles were admitted via the broad HZ compilation.
Discoveries by year
All 59 catalog rows, by discovery/confirmation year.
Findings
12 planets are roughly Earth-size (radius below 1.3 R⊕), including Kepler-1649 c at 1.06 R⊕ and TOI 700 d at 1.07 R⊕ — see
science.nasa.gov.
The catalog also holds giants near 10 Earth radii, such as Kepler-1708 b (737-day orbit) — habitable-zone here means orbital distance, not Earth-likeness:
exoplanetarchive.ipac.caltech.edu.
2025 leads with 14 catalog entries, followed by 2023 with 12; 2020 and 2021 have 7 each — broad HZ compilation at
exoplanetatlas.com.
Only 7 of 59 rows carry explicit habitable-zone wording from their own source, e.g. Gliese 251 c and TOI-2093 c — the rest rely on the linked compilation:
exoplanetatlas.com.
Method and caveats
- No single accepted habitable-zone roster exists: boundaries depend on stellar and climate assumptions, so this is a broad, inclusive catalog — not a claim that any planet is habitable.
- Several entries are gas giants, mini-Neptunes, or edge-of-zone objects rather than Earth analogues.
- Discovery year vs later confirmation is ambiguous for some planets; the year shown is the catalog's discovery/confirmation year.
- Some radii for non-transiting planets are catalog estimates, not direct transit measurements.
- Blank period or radius means no reliable value was resolved from the pages scanned; missing measurements are never inferred.
Broad habitable-zone catalog: 59 confirmed exoplanets with discovery/confirmation years 2020–2025, search current through 2026-09-01. Period in Earth days, radius in Earth radii; parameters resolved from NASA exoplanet catalog and NASA Exoplanet Archive pages (1–8 pages checked per planet); HZ membership via explicit source wording or a broad habitable-exoplanet compilation. 23 rows plot in the scatter; 36 lack a period or radius and appear in the table only.
