Asteroid Bennu's most prominent boulder, a rock chunk jutting out 71 ft (21.7 m) from the asteroid's southern hemisphere, finally has a name. The boulder—which is so large that it was initially detected from Earth—is officially designated Benben Saxum after the primordial hill that first arose from the dark waters in an ancient Egyptian creation myth.
