KIC 9832227 is a contact binary star system in the constellation Cygnus, located about 2,060 light-years away.

[4] In 2017, the system was predicted to result in a merger in 2022.2 (± 0.6 years), producing a luminous red nova (LRN) reaching an apparent magnitude of 2,[7] or about the brightness of Polaris, the North Star.

The merger of the two stellar cores was predicted to give birth to a new, hotter, more massive main-sequence star.

[8][9][10] The period of the variations in KIC 9832227 has been observed to be growing shorter since 2013, leading to the prediction of the merger in or around 2022.

[11] In September 2018, it was announced that the original prediction was based on a dataset which timing had been erroneously offset by 12 hours—an error which appeared to exaggerate the decay rate of the orbital period.
