Kepler-186 b is a charming little world orbiting the distant star Kepler-186, discovered in 2014 thanks to the trusty eyes of the Kepler Space Telescope. This planet was spotted using the transit method, where it gracefully passes in front of its star, causing a tiny dip in brightness that's just enough to catch astronomers' attention. While it’s not as famous as its sibling Kepler-186 f, this pint-sized planet still holds its own cosmic allure. Located in a far-off corner of space, Kepler-186 b orbits its star closer than Earth does around the Sun, making it likely a hot, rocky world. It’s a perfect example of how even the smallest planets can captivate our curiosity in the vastness of the galaxy!
