Kepler-385

Kepler-385 (also designated KOI-2433) is an F-type main-sequence star located about 4900 ly away from Earth in the constellation of Cygnus. The star is 10% larger and 5% hotter than the Sun. The star has at least three, and potentially up to seven, exoplanets discovered orbiting it.

The star has a mass of 1.05 solar masses, a radius of 1.157 solar radii, a temperature of 5829 Kelvin and a luminosity of 1.39 times the solar luminosity.

Planetary system
Kepler-385 was observed by the Kepler space telescope, which initially detected a total of seven planet candidates. Two of these, KOI-2433.01 & .02, were confirmed in 2014 as Kepler-385 b & c, and a third, KOI-2433.03, was confirmed in 2020 as Kepler-385 d. These confirmations were part of studies using statistical validation to confirm large numbers of Kepler candidates. The candidate KOI-2433.05 was shown to be a false positive.

In 2023, a new updated catalog of Kepler candidates was presented, including an eighth candidate around Kepler-385, KOI-2433.08, making it a candidate seven-planet system. Kepler-385 is tied with Kepler-90 - a confirmed eight-planet system - as the Kepler system with the most planet candidates.
