The planets of the Kepler-138 system have received different KOI names when they were confirmed: As Kepler candidates, the names are K000314.01 (or KOI-314.01), K000134.02 (or KOI-314.02) and K000314.03 (or KOI-314.03). Kipping et al. (2014) and Rowe et al. (2014) simultaneously gave different names to the two exterior planets: Kipping et al. confirm and name KOI-314.01 as KOI-314 b et KOI-314.02 as KOI-314 c and do not confirm the reality of KOI-134.03. Rowe et al. confirm statistically the 3 planets and name KOI-134.03 as KOI-134b, KOI-134.01 as KOI-134c and KOI-134.02 as KOI-134d. The Kepler team names K000314.01 as Kepler-138 c, K000314.02 as Kepler-138 d and K000314.03 as Kepler-138 b
