Kepler-160


Kepler-160 is a main sequence star located in the constellation Lyra in the field of view of 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 two confirmed, one unconfirmed and at least one suspected planets orbiting it.

Characteristics

The star Kepler-160 is rather old, having no detectable circumstellar disk. The star's metallicity is unknown, with conflicting values of either 40% or 160% of solar metallicity reported.
The Breakthrough Listen search for extraterrestrial intelligence around Kepler-160 have resulted in a non-detection of the technosignatures in 2020.

Planetary system

The two planetary candidates in the Kepler-160 system were discovered in 2010, published in early 2011 and confirmed in 2014.The planets Kepler-160b and Kepler-160c are not in orbital resonance despite their orbital periods ratio being close to 1:3.
An additional rocky transiting planet candidate :ja:KOI-456.04|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, :ja:KOI-456.04|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. Perhaps most important, it receives about 93% as much light as Earth gets from the sun. 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.
