Meet K2-166 b, a charming little world orbiting the star K2-166, discovered in 2018 by the ever-watchful Kepler space telescope using its trusty CCD array camera. This space-detected planet was found as it gracefully transited, or passed in front of, its star, causing just the right tiny dip in brightness to catch astronomers’ eyes. Though details about its size and atmosphere remain a mystery waiting to be unraveled, K2-166 b orbits in the fascinating K2 field, a cosmic neighborhood filled with intriguing exoplanets. It’s a perfect example of how even the smallest shadows in distant starlight reveal entire worlds, turning the universe into a grand, ongoing treasure hunt for curious explorers from Earth.
