Kepler-1972 or KOI-3184 is a G-Type main sequence Sun-like star located 923 light years away from Earth in Lyra Constellation. The discovery by A. Leleu with transmit method and published in Cornell University
Characteristics[edit]
Mass, gravity and radius[edit]
According to Cornell University, its solar mass is 1.18, the solar radius is 1.12 and its gravity is roughly 4.46 cgs[1]
Temperature[edit]
Its spectral class is classified as G1V, it would be assumed for its temperature is 5,818 Kelvin[1]
Planetary System[edit]
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.[1]
