NASA Study Finds Near-Earth Asteroid Is Actually Comet

The mystery began on Aug. 28, 2025, when the object—known as asteroid 1998 SH2—passed safely within 2 million miles of our planet during its four-and-a-half-year orbit around the Sun. But when 1998 SH2 failed to appear where scientists expected, it became clear that something unanticipated had been influencing the object’s motion.
