Kepler-1972 (KOI-3184) is a solitary G-type star in the northern constellation of Lyra, some 923 ly distant. It is similar in temperature to the Sun, but 12% more massive, 38.4% larger and roughly twice as bright. It is host to two confirmed exoplanets and a third planet is suspected. It is located at the celestial coordinates: right ascension 19:13:34.9, declination +39°52′21.5″.

Position
Kepler-1972 is located in the western portion of constellation Lyra, placing it near the southern edge of Kepler's field of view. It is situated 10.6″ west of and 43′36″ north of Eta Lyrae (η Lyrae; Aladfar), a 4th-magnitude B-type subgiant 10 times more massive than the Sun and 19,000 times more luminous, at 1390 ly away, which is part of a spectroscopic binary and an optical double.

Stellar characteristics
Kepler-1972 is a G-type star at the end of its main sequence lifespan.

It has an apparent magnitude of 11.2, making it too dim to be seen from Earth by the naked eye, but observable using a 35 mm aperture telescope.

Planetary system
Kepler-1972 is host to two confirmed planets and at least one additional planetary candidate. All three planets are smaller than Earth.

Size comparison
The chart below shows an approximate size comparison between the three planets around Kepler-1972 (two confirmed, one candidate), alongside Earth (6371.0 km; 1 ) and Mars (3,398.5 km; 0.533 ) for reference.
