Meet K2-357 b, a fascinating little world discovered in 2021 orbiting the star K2-357, far beyond our solar system. This exoplanet was spotted using the powerful Kepler Space Telescope, which detects planets by the subtle dip in starlight as they transit—or pass in front of—their host star. K2-357 b is a close-in planet, hugging its star tightly, which means it’s likely a sizzling, rocky orb where days are incredibly swift compared to Earth’s. Though it’s many light-years away and not quite the vacation getaway you might dream of, studying K2-357 b helps astronomers understand the diversity of planetary systems scattered across our galaxy. It’s a tiny but intriguing puzzle piece in the grand cosmic jigsaw!
