Asteroid Bennu

New findings suggest asteroid Bennu, a near-Earth object studied by NASA's OSIRIS-REx mission, may have originated much closer to the Sun than previously believed, challenging existing models of how the solar system's early materials were distributed. Scientists say the asteroid's composition could indicate it formed in a warmer region before migrating outward.

New reporting says asteroid Bennu, a near-Earth asteroid studied closely by NASA's OSIRIS-REx mission, may have originated in a region of the solar system that scientists did not previously expect. The finding could change how researchers understand Bennu's composition and the early solar system's history.

New analysis of tiny grains from asteroid Bennu suggests the samples hold clues about how Jupiter influenced the formation and arrangement of the early Solar System. The findings point to material preserved from the Solar System's infancy, offering scientists a rare record of conditions during planet formation. Researchers say the grains could refine models of how giant planets shaped the distribution of rocky material.

New reporting says asteroid Bennu, the near-Earth object studied by NASA's OSIRIS-REx mission, likely originated in an unexpected region of the early solar system rather than the main asteroid belt where scientists assumed it formed. The findings could reshape understanding of how the solar system's building blocks were distributed and delivered water and organic material to Earth.
