Meet KMT-2017-BLG-2331L b, a fascinating exoplanet discovered in 2024 by the clever use of microlensing, a cosmic magnifying glass effect, thanks to the keen eyes of the KMTNet team and their trusty 18k Mosaic CCD camera. This distant world orbits the star KMT-2017-BLG-2331L and was spotted from our own backyard here on Earth, proving that sometimes the best astronomical adventures happen right under our noses—or at least through ground-based telescopes. While it doesn’t yet have a catchy nickname, this planet stands as a shining example of how astronomers can find new worlds lurking in the faintest flickers of light, expanding our treasure map of the galaxy one discovery at a time.
