An analytical overview into the detection of Kepler-37b, the smallest confirmed exoplanet discovered orbiting a sun-like star. This episode examines how high-precision transit photometry and asteroseismology revealed a miniature, moon-sized world blocking an impossibly faint fraction of starlight. Follow astronomers as they evaluate light-curve anomaly data, cross-examine planetary density metrics, and re-assess cosmological models governing the lower size limits of rocky exoplanets in the galaxy.
