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, [3] [2] has three confirmed planets and one unconfirmed planet orbiting it.

Characteristics

The star Kepler-160 is rather old, having no detectable circumstellar disk. [5] The star's metallicity is unknown, with conflicting values of either 40% or 160% of solar metallicity reported. [6] [7]

Despite having at least one potentially Earth-like planet (KOI-456.04), the Breakthrough Listen search for extraterrestrial intelligence found no potential technosignatures. [8]

Planetary system

The two planetary candidates in the Kepler-160 system were discovered in 2010, published in early 2011 [9] and confirmed in 2014. [10] The planets Kepler-160b and Kepler-160c are not in orbital resonance despite their orbital periods ratio being close to 1:3. [11]

An additional rocky transiting planet candidate KOI-456.04, located in the habitable zone, was detected in 2020, [2] 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. [12] 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. [2]

KOI-74 is an eclipsing binary star in the constellation of Cygnus. The primary star is an A-type main-sequence star with a temperature of 9,400 K. It lies in the field of view of the Kepler Mission and was determined to have a companion object in orbit around it which is smaller and hotter than the main star.

Kepler-223 is a G5V star with an extrasolar planetary system discovered by the Kepler mission. Studies indicate that the Kepler-223 star system consists of 4 planets orbiting the star.

Kepler-15 (also known as KOI-128 or KIC 11359879 is a G-type main sequence star with a mass of 1.018 solar masses and a radius of 1.253 solar radius. The star lies at a temperature of 5595 Kelvin.

Kepler-33 is a star about 4,000 light-years in the constellation of Cygnus, with a system of five known planets. Having just begun to evolve off from the main sequence, its radius and mass are difficult to ascertain, although data available in 2020 shows its best-fit mass of 1.3M☉ and radius of 1.6R☉ are compatible with a model of a subgiant star.

Kepler-80, also known as KOI-500, is a red dwarf star of the spectral type M0V. This stellar classification places Kepler-80 among the very common, cool, class M stars that are still within their main evolutionary stage, known as the main sequence. Kepler-80, like other red dwarf stars, is smaller than the Sun, and it has both radius, mass, temperatures, and luminosity lower than that of our own star. Kepler-80 is found approximately 1,223 light years from the Solar System, in the stellar constellation Cygnus, also known as the Swan.

<span class="mw-page-title-main">Kepler-37b</span> Sub-Earth orbiting Kepler-37, currently the smallest known exoplanet

Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. As of February 2013, it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. The measurements do not constrain its mass, but masses above a few times that of the Moon give unphysically high densities.

Kepler-32 is an M-type main sequence star located about 1053 light years from Earth, in the constellation of Cygnus. Discovered in January 2012 by the Kepler spacecraft, it shows a 0.58 ± 0.05 solar mass (M☉), a 0.53 ± 0.04 solar radius (R☉), and temperature of 3900.0 K, making it half the mass and radius of the Sun, two-thirds its temperature and 5% its luminosity.

Kepler-23c is a Neptune-sized exoplanet orbiting the star Kepler-23, located in the constellation Cygnus. The planet is 3.12 times wider than the Earth and is 0.189 Jupiter masses. The planet was discovered using data taken from the Kepler spacecraft. It is likely a gas giant.

Kepler-186e is a confirmed exoplanet orbiting the red dwarf star Kepler-186, approximately 582 light years away from Earth in the constellation of Cygnus. It is near the optimistic habitable zone but probably not in it, possibly making it have a runaway greenhouse effect, like Venus. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Four additional planets orbiting the star were also discovered.

KOI-5 is a triple star system composed of three stars: KOI-5 A, KOI-5 B and KOI-5 C, orbiting 1,870±70 light-years away.

Kepler-1658b is a hot Jupiter, a type of gas giant exoplanet, that orbits an F-type star called Kepler 1658, located about 2629 light-years away from the Solar System. It is the first planet identified by the Kepler space telescope after its launch in 2009, but later ruled out as false alarm since its transit could not be confirmed. A study published in 2019 established it as a planet, describing it as "the closest known planet in terms of orbital period to an evolved star." Analysis of the Transiting Exoplanet Survey Satellite (TESS) data in 2022 showed that it is gradually spiraling into its star.
