Kepler-1972 or KOI-3184 is a G-type main sequence Sun-like star located 923 light years away from Earth in the constellation of Lyra.

Characteristics

=Mass, gravity and radius=

Its solar mass is 1.18, the solar radius is 1.12 and its gravity is roughly 4.46 cgs{{Clarify|date=May 2025}}.

=Temperature=

Its spectral class is classified as G1V, it would be assumed for its temperature is 5,818 Kelvin.

Planetary system

Kepler-1972 has 2 exoplanets orbiting it. These planets are suspected since 2022, for their same mass and radius and their temperature is higher due to their being closest to its host star.
