K2-141 b is an extraordinary exoplanet orbiting the star K2-141, discovered in 2018 using the keen eyes of the Kepler Space Telescope's CCD Array. This fiery world boasts an ultra-close orbit, making it a scorcher with a dayside so hot that rocks might melt into rivers of lava! Imagine a place where one side is a blazing furnace while the other remains in perpetual darkness, freezing cold. K2-141 b is a dazzling example of a "lava world," showcasing the wild extremes planets can face beyond our solar system. Its discovery through the transit method means we catch a tiny, precious dimming of its star’s light as K2-141 b sweeps across, giving us a glimpse into this extreme alien neighborhood.
