KOI-433.02 m is a predicted exomoon around the candidate planet KOI-433.02. If the planet, observed by the Kepler telescope is confirmed, it is expected that, based on the general rule for planet-to-satellite(s) mass ratio of 10,000:1[1] one or more satellites could exist in orbit around it. If a single moon indeed existed, based on this predicted mass and the orbital properties of its parent planet and star, it could have an ESI rating of 0.93,[2] meaning it would not only be the most Earth-like exomoon, but the most Earth-like planetary mass object overall, as the highest ESI rating for a planet is 0.88.[3] However, it has not been observed, merely predicted.[4]
