K2-148b
K2-148b is a confirmed Super-Earth, probably rocky, closely orbiting a small orange dwarf star. It is the innermost of three Super-Earths around the star K2-148, which is in a wide binary pair with the M0.5V red dwarf EPIC 220194953. K2-148b is the smallest planet of the system, at about a third larger than Earth, and could be terrestrial in nature. However, the three planets do not exhibit significant transit timing variations, implying that they could have relatively low masses. The planet was validated in early 2018 by Hirano "et al." and is too hot for known life.
Kepler-124b
It is the smallest discovered planet in the Kepler-124 system, and has the closest orbit of the three known planets. Kepler-124b orbits 96% closer to its star than Earth (approximately 3 Earth days), which in the Kepler-124 system is inside the inner limit of the star's habitable zone.
