Carl Hergenrother, OSIRIS-REx Asteroid Astronomy Lead and Target Asteroids! Co-lead, compiles the list by selecting near-Earth objects that are greater than 200 meters in size and are relatively easy to access for sample return spacecraft missions. Additional brighter, Main-belt asteroids that are analogues to (101955) Bennu have been added too. This list is dynamic and will change over the course of the mission as we learn more about these objects and astronomers discover new objects.
