Kepler-138 b is a charming little world orbiting the star Kepler-138, discovered back in 2014 by the keen eyes of the Kepler space telescope. This exoplanet was spotted using the transit method, which means it reveals itself by crossing in front of its star and causing a tiny, telltale dip in starlight. Though it's a bit on the small side compared to some other exoplanets, Kepler-138 b has captured the imagination of planet hunters everywhere. Its home system sits far beyond our solar neighborhood, in the vast depths of the Kepler field of view, making it a fascinating destination for future cosmic explorers dreaming about new worlds beyond our own.
