Kepler-160 is a main-sequence star approximately the width of our Galactic arm away in the constellation Lyra, first studied in detail by the Kepler Mission, a NASA-led operation tasked with discovering terrestrial planets. The star, which is very similar to the Sun in mass and radius, has three confirmed planets and one unconfirmed planet orbiting it.
Characteristics
The star Kepler-160 is rather old, having no detectable circumstellar disk.{{cite journal|arxiv=1112.0368|doi=10.1088/0004-637X/752/1/53|title=Debris Disks Inkeplerexoplanet Systems|year=2012|last1=Lawler|first1=S.

Planetary system
The two planetary candidates in the Kepler-160 system were discovered in 2010, published in early 2011{{cite journal|arxiv=1102.0543|doi=10.1088/0067-0049/197/1/8|title=Architecture and Dynamics of Kepler 's Candidate Multiple Transiting Planet Systems|year=2011|last1=Lissauer|first1=Jack J.|last2=Ragozzine|first2=Darin|last3=Fabrycky|first3=Daniel C.|last4=Steffen|first4=Jason H.|last5=Ford|first5=Eric B.|last6=Jenkins|first6=Jon M.|last7=Shporer|first7=Avi|last8=Holman|first8=Matthew J.|last9=Rowe|first9=Jason F.|last10=Quintana|first10=Elisa V.|last11=Batalha|first11=Natalie M.|last12=Borucki|first12=William J.|last13=Bryson|first13=Stephen T.|last14=Caldwell|first14=Douglas A.|last15=Carter|first15=Joshua A.|last16=Ciardi|first16=David|last17=Dunham|first17=Edward W.|last18=Fortney|first18=Jonathan J.|last19=Gautier, Iii|first19=Thomas N.|last20=Howell|first20=Steve B.|last21=Koch|first21=David G.|last22=Latham|first22=David W.|last23=Marcy|first23=Geoffrey W.|last24=Morehead|first24=Robert C.|last25=Sasselov|first25=Dimitar|journal=The Astrophysical Journal Supplement Series|volume=197|issue=1|page=8|bibcode=2011ApJS..197....8L|s2cid=43095783}} and confirmed in 2014.[https://exoplanet.eu/catalog/kepler_160_b--2173/ Planet Kepler-160 b on exoplanet.eu] The planets Kepler-160b and Kepler-160c are not in orbital resonance despite their orbital periods ratio being close to 1:3.{{cite journal|arxiv=1111.0299|doi=10.1111/j.1745-3933.2011.01185.x|title=Identifying non-resonant Kepler planetary systems|year=2012|last1=Veras|first1=Dimitri|last2=Ford|first2=Eric B.|journal=Monthly Notices of the Royal Astronomical Society: Letters|volume=420|issue=1|pages=L23–L27|doi-access=free |bibcode=2012MNRAS.420L..23V|s2cid=55625425}}
An additional rocky transiting planet candidate KOI-456.04, located in the habitable zone, was detected in 2020, and more non-transiting planets are suspected due to residuals in the solution for the transit timing variations. From what researchers can tell, KOI-456.04 looks to be less than twice the size of Earth and is apparently orbiting Kepler-160 at about the same distance from Earth to the sun (one complete orbit is 378 days). Perhaps most important, it receives about 93% as much light as Earth gets from the sun.{{Cite web|last=Patel|first=Neel V.|date=2020-06-05|title=Astronomers have found a planet like Earth orbiting a star like the sun|url=https://www.technologyreview.com/2020/06/05/1002831/kepler-160-koi-456-04-earth-sun-exoplanet-habitable/|access-date=2020-06-07|website=MIT Technology Review|language=en}} Nontransiting planet candidate Kepler-160d has a mass between about 1 and 100 Earth masses and an orbital period between about 7 and 50 d.
