cds-question@unistra.frmultiple-starsexoplanetsstellar-radiistellar-massesmilky-way-galaxyeffective-temperaturestellar-distancevisible-astronomytrigonometric-parallaxTransit observations have found the majority of exoplanets to date. Also spectroscopic observations of transits and eclipses are the most commonly used tool to characterize exoplanet atmospheres and will be used in the search for life. However, an exoplanet's orbit must be aligned with our line of sight to observe a transit. Here, we ask, from which stellar vantage points would a distant observer be able to search for life on Earth in the same way? We use the TESS Input Catalog and data from Gaia DR2 to identify the closest stars that could see Earth as a transiting exoplanet: We identify 1004 main-sequence stars within 100 parsecs, of which 508 guarantee a minimum 10-h long observation of Earth's transit. Our star list consists of about 77 percent M-type, 12 percent K-type, 6 percent G-type, 4 percent F-type stars, and 1 percent A-type stars close to the ecliptic. SETI searches like the Breakthrough Listen Initiative are already focusing on this part of the sky. Our catalogue now provides a target list for this search. As part of the extended mission, NASA's TESS will also search for transiting planets in the ecliptic to find planets that could already have found life on our transiting Earth.2020MNRAS.499L.111Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/499/L111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/499/L111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/499/L111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/499/L111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/499/L111https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/499/L111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/499/L111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/499/L111/table1 (Closest stars in the Earth transit zone)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/L111/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/L111/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/L111/table1?GETtext/xml+votable180.050000true96.1720203723.433038150.0055555555555555565/257 4573 4679-4680 6779 7227 6/238-239 247 250 252 351 359 362-366 369-372 395 397-399 402-403 405-406 408-409 417-418 448 527 533-536 538 544-545 576-578 580 1027 1032-1033 1040 4317 4319 4340 4342 4345 4347 4359 4365 4367-4368 4370 4387-4390 4393 4395-4396 4480 4482 4679 4685-4686 4688 4690 4707-4708 4710 4712-4714 4757 4759 4763-4766 4783 4785-4788 4800 6147-6148 6153-6155 6176 18090 18104 18138 18142 18149 18284 18291 18312-18313 18495 18538-18539 18541-18542 18550-18553 18556 18567-18568 18570-18571 18578-18579 18581-18582 18624 18714-18715 18724-18725 18736 18758-18761 18768-18770 18772-18773 19456 23925 23927 23931-23932 23995 23997-23998 24007 24011-24014 24016 24018 24033-24034 24183 24187 24189-24190 24246-24247 24249-24250 24252 24263 24266-24270 24272-24274 24288 24290 24333-24334 24337-24338 24353-24356 25599 25668-25670 25676 25678 25697-25699 25705-25706 25751 25757-25758 25782 25787 26127-26130 26136 26138 26151 26157-26158 26244 26249 26251 26272-26273 26275 26280 26282 26965 26967 26972-26974 26995-26996 26998 27003-27004 27089-27091 27096 27109 27111 27455 27460 27462 27465 27467 27489-27490 27496 27498 27541 27543 27548 27550 27569 27571-27572 27576-27578 28891-28894 28907 28913-28914 28920 28957-28959 28973-28974 28977 28979-28980 28995 28998 29000-29002 29057-29058 29213-29215 29229 29231 29233-29236 29240 29248-29250 29252 29313 29315-29317 29320-29322 42975 42997-42999 43001-43004 44351 44359 44364 44366 44368 44385-44388 44392 44394 44436-44438 44441 44443-44444 44446 44462-44466 44472 44669 44671 44755-44756 44758 44761 44763 44783-44786 44792 44803-44804 44806 44809-44811 44832 44834 48117-48118 48121-48124 48571 48574-48575 48603 48606-48607 48611 48613-48617 48620 48624-48625 48628 48734-48735 48742 48744-48746 48748 48752-48753 48756 48779 48781-48782 48786-48789 48800-48801 48902-48905 48912-489133.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/499/L111?format=asciiOpticaldefaultJ/MNRAS/499/L111/table1Closest stars in the Earth transit zonerecnoRecord number assigned by the VizieR team.
