What is The Smallest Known Planet? #space #astronomy #universe

Kepler 37-b, discovered in 2013 and lying 209 light-years away, is currently the smallest known planet, surpassing even Mercury in diminutiveness and closely resembling Earth's Moon in size. Identified using the Kepler space telescope via the transit method, this celestial body orbits its star in a mere 13.4 days.

Its rocky, atmosphere-less surface mirrors the harsh conditions found on Mercury. Despite its tiny stature, Kepler 37-b meets all planetary criteria, expanding our understanding of planetary diversity. As astronomical technologies advance, the discovery of even smaller exoplanets remains a tantalizing possibility, promising to further enrich our knowledge of the universe's vast complexities.
