This will be a major step forward in our understanding of exoplanet diversity and the prevalence of potentially habitable conditions beyond the Earth. We compute a list of currently known exoplanets detectable with the mid-infrared Large Interferometer For Exoplanets (LIFE) in thermal emission. We also compute the list of known exoplanets accessible to a notional design of the future Habitable Worlds Observatory (HWO), observing in reflected starlight. With a pre-existing statistical methodology, we processed the NASA Exoplanet Archive and computed orbital realizations for each known exoplanet. We derived their mass, radius, equilibrium temperature, and planet-star angular separation. We used the LIFEsim simulator to compute the integration time (tint) required to detect each planet with LIFE. A planet is considered detectable if a broadband signal-to-noise ratio S/N=7 is achieved over the spectral range 4-18.5um in t_int_<100h. We tested whether the planet is accessible to HWO in reflected starlight based on its notional inner and outer working angles, and minimum planet-to-star contrast. LIFE's reference configuration (four 2-m telescopes with 5% throughput and a nulling baseline between 10-100m) can detect 212 known exoplanets within 20 pc. Of these, 49 are also accessible to HWO in reflected starlight, offering a unique opportunity for synergies in atmospheric characterization. LIFE can also detect 32 known transiting exoplanets. Furthermore, we find 38 LIFE-detectable planets orbiting in the habitable zone, of which 13 have Mp<5M_{Earth}_ and eight have 5M_{Earth}_<Mp<10M_{Earth}_. LIFE already has enough targets to perform ground-breaking analyses of low-mass, habitable-zone exoplanets, a fraction of which will also be accessible to other instruments.2023A&A...678A..96Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/678/A96CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/678/A96https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/678/A96http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/678/A96https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/678/A96https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/678/A96http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/678/A96GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/678/A96/tableg1 (Catalogue of all the known exoplanets within 20pc produced with our statistical methodology)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/678/A96/tableg1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/678/A96/tableg1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/678/A96/tableg1?GETtext/xml+votable180.050000true217.4289381-62.67949190.0055555555555555566/22 250 546 2472 2515 2622 2737 3715 3900 3979 5009 5207 5309 5420 5488 5522 5849 6219 6672 7264 7395 7471 8357 8588 8843 9403 9662 9750 9843 10004 10146 10149 10225 10278 11177 11636 11671 12592 12732 12983 14278 14419 15052 15792 16213 16342 16758 16847 17425 18496 18666 18726 19131 19912 20071 20145 20886 20896 21171 22309 22645 22708 23363 23867 24227 24713 24924 25055 25238 25989 26521 26538 26555 26560 26575 26972 27088 27392 27912 27973 28040 28548 30015 30176 30429 30505 30771 31216 31478 32259 32335 32491 32848 32930 33210 33243 33717 33813 33966 34005 34054 34181 34345 34446 34448 34481 34561 34905 34924 35079 36614 36697 37041 37453 37477 37942 38238 38456 38461 38464 39807 40250 40513 40692 41591 41941 42101 42248 42255 42290 42314 42459 42700 42760 42845 43203 44379 44921 45372 45564 45668 46244 46566 46632 47740 48274 48500 48652https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/678/A96?format=asciidefaultJ/A+A/678/A96/tableg1Catalogue of all the known exoplanets within 20pc produced with our statistical methodologySimbadNameSimbad column added by the CDSmeta.idcharnullablePlanetPlanet Name (pl_name)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
