KMT-2023-BLG-0466L is a Sun-like G-type star (about 0.44 solar masses, 5,778 K), 6,800 light-years from Earth. KMT-2023-BLG-0466L b is a 3.25-Jupiter-mass companion, at 2.680 AU from its star, discovered in 2026 via microlensing. Microlensing detections occur when a foreground star's gravity briefly magnifies a background source, revealing planets that are otherwise too faint and distant to observe directly. KMT-2023-BLG-0466L b circles in the outer system, comparable to the Jupiter region. At roughly 6,800 light-years, KMT-2023-BLG-0466L lies far beyond the nearest stars yet remains reachable to large survey telescopes.
