Kepler-23 is a G-type main-sequence star about away in the northern constellation of Cygnus, the swan. With an apparent visual magnitude of 13.5, it is too faint to be seen with the naked eye. This star is similar in mass and temperature to the Sun, but is larger and more luminous. Kepler-23 is orbited by three known exoplanets.

Kepler-29 is a Sun-like star in the northern constellation of Cygnus. It is located at the celestial coordinates: Right Ascension , Declination . With an apparent visual magnitude of 15.456, this star is too faint to be seen with the naked eye. It is a solar analog, having a close mass, radius, and temperature as the Sun. Currently the age of the star has not been determined due to its 2780 light-year (850 parsecs) distance. As of 2016 no Jovian exoplanets of 0.9–1.4 have been found at a distance of 5 AU.

PH2, also known as Kepler-86, or KIC 12735740 (2MASS J19190326+5157453), is an F-type main-sequence star distant within the constellation Cygnus. Roughly the size and temperature of the Sun, PH2 gained prominence when it was known to be the host of one of 42 planet candidates detected by the Planet Hunters citizen science project in its second data release. The candidate orbiting around PH2, known as PH2b, had been determined to have a spurious detection probability of only 0.08%, thus effectively confirming its existence as a planet.

Kepler-44, formerly known as KOI-204, is a star in the northern constellation of Cygnus. With an apparent visual magnitude of 15.0 this star is too faint to be seen with the naked eye.

Kepler-31 is a star in the northern constellation of Cygnus, the swan. It is orbited by three known exoplanets. It is located at the celestial coordinates: Right Ascension , Declination . With an apparent visual magnitude of 14.0, this star is too faint to be seen with the naked eye.

Kepler-443b is an exoplanet about 2,540 light-years from Earth. It has an 89.9 percent chance of being in the star's habitable zone, yet only a 4.9 percent chance of being rocky.

Kepler-39b (formerly known as KOI-423b), is a confirmed extrasolar object (either a Jovian planet or brown dwarf because of its mass) discovered orbiting the F-type star Kepler-39. It is eighteen times more massive than Jupiter, and is about five fourths its size. The planet orbits its host star at about 15% of the average distance between the Earth and Sun. Kepler-39b's host star was investigated by European astronomers along with three other stars, including the host star of Kepler-40b, using equipment at the Haute-Provence Observatory in France.

Kepler-1520b (initially published as KIC 12557548 b), is a confirmed exoplanet orbiting the K-type main sequence star Kepler-1520. It is located about 2,020 light-years (620 parsecs) away from Earth in the constellation of Cygnus. 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. The planet was previously proposed in 2012 when reports of its host star recorded drops in its luminosity varying from 0.2% to 1.3%, which indicated a possible planetary companion rapidly disintegrating. In 2015, the pl

Kepler-47b (also known as Kepler-47 (AB) b and by its Kepler Object of Interest designation KOI-3154.01) is an exoplanet orbiting the binary star system Kepler-47, the innermost of three such planets discovered by NASA's Kepler spacecraft. The system, also involving two other exoplanets, is located about 3,400 light-years (1,060 parsecs) away.

L1014 is a dark nebula in the Cygnus constellation. It may be among the most centrally condensed small dark clouds known, perhaps indicative of the earliest stages of star formation processes. This cloud harbors at its core a very young low-mass star named L1014 IRS; some astronomers have suggested that this object may be a brown dwarf or even a rogue planet at the earliest stage of its lifetime.

Kepler-432b (also known by its Kepler Object of Interest designation KOI-1299.01) is a hot super-Jupiter (or "warm" super-Jupiter) exoplanet orbiting the giant star Kepler-432 A, the innermost of two such planets discovered by NASA's Kepler spacecraft. It is located about 2,830 light-years (870 parsecs, or nearly km) from Earth in the constellation Cygnus. 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.

Kepler-40b, formerly known as KOI-428b, is a hot Jupiter discovered in orbit around the star Kepler-40, which is about to become a red giant. The planet was first noted as a transit event by NASA's Kepler spacecraft. The Kepler team made data collected by its satellite publicly available, including data on Kepler-40; French and Swiss astronomers used the equivalent to one night of measurements on the SOPHIE échelle spectrograph to collect all the data needed to show that a planet was producing the periodic dimming of Kepler-40. The planet, Kepler-40b, is twice the mass of Jupiter and slightly

Kepler-84 is a Sun-like star 3,339 light-years from the Sun. It is a G-type star. The stellar radius measurement has a large uncertainty of 48% as in 2017, complicating the modelling of the star. The Kepler-84 star has two suspected stellar companions. Four stars, all more than four magnitudes fainter than Kepler-84, are seen within a few arcseconds and at least one is probably gravitationally bound to Kepler-84. Another, which has only a 0.005% chance of being a background star, is a yellow star with mass at a projected separation of 0.18″ or 0.26″ (213.6 AU).
