An analysis published in June 2026 shows that the roughly eight-kilometre body does not simply turn around one steady axis; it slowly tumbles. Its surface also preserves chemical evidence of contact with liquid water, probably from a time before the present asteroid formed. How can a spacecraft discover all this during a brief flyby?
