Kepler-1513
Kepler-1513 is a main-sequence star about  away in the constellation Lyra. It has a late-G or early-K spectral type, and it hosts at least one, and likely two, exoplanets. Planetary system 
Kepler-1513b (KOI-3678.01) was confirmed in 2016 as part of a study statistically validating hundreds of Kepler planets. In November 2022, an exomoon candidate was reported around Kepler-1513b based on transit-timing variations (TTVs). Unlike previous giant exomoon candidates in the Kepler-1625 and Kepler-1708 systems, this exomoon would have been terrestrial-mass, ranging from 0.76 Lunar masses to 0.34 Earth masses depending on the planet's mass and the moon's orbital period. In October 2023, a follow-up study by the same team of astronomers using additional observations found that the observed TTVs cannot be explained by an exomoon, but can be explained by a second, outer planet, Kepler-1513c, with a mass comparable to Saturn.
