Giant Asteroid Spinning Every Four Minutes Puzzles Scientists
Original: asteroid
Scientists are studying a giant asteroid that completes a full rotation roughly every four minutes, an unusually fast spin for an object its size. Researchers say they are not certain how the asteroid holds together at such speeds, since rapid rotation should in theory tear loosely bound bodies apart, and its internal structure remains unclear.
Why now: New research into the asteroid's remarkably fast rotation has sparked curiosity about how such a large object stays intact.
