Unfortunately, a phenomenon called the Yarkovsky effect can make these predictions difficult over long time periods. How does this effect work?
When sunlight strikes a rotating asteroid, the dayside heats up; as the asteroid turns, the night side cools and releases the heat, exerting a small thrust that can change the asteroid's direction over time. In order to learn more about this process on asteroid Bennu, NASA is sending a spacecraft called OSIRIS-REx to make detailed observations of Bennu's shape, brightness, and surface features. These factors are thought to influence the Yarkovsky effect, and understanding how will enable scientists to better predict the orbit of Bennu and other near-Earth asteroids.", "items": [], "extra_data": {} }, { "id": 344037, "url": "https://svs.gsfc.nasa.gov/11964/#media_group_344037", "widget": "Video player", "title": "", "caption": "", "description": "ANIMATION -

During that time, the spacecraft gathered information about Bennu’s size, shape, mass, and composition while monitoring its spin and orbital trajectory. Before leaving the near-Earth object May 10, 2021, the spacecraft scooped up a sample of rock and dust from the asteroid’s surface. OSIRIS-REx will return the sample to Earth Sept. 24, 2023, for further scientific study.The teleconference will stream live online at: http://www.nasa.gov/liveParticipants in the briefing will be:•Dante Lauretta, study co-author and OSIRIS-REx principal investigator at the University of Arizona in Tucson•Davide Farnocchia, study lead author and scientist with the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory in Southern California•Jason Dworkin, OSIRIS-REx project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland•Lindley Johnson, planetary defense officer at NASA’s Planetary Defense Coordination Office at NASA Headquarters in WashingtonFor more information about the OSIRIS-REx mission to Bennu, visit: https://www.nasa.gov/osiris-rexLearn more about asteroid Bennu’s updated impact hazard.Read the science paper on Icarus. || ", "release_date": "2021-08-11T12:00:00-04:00", "update_date": "2023-05-03T13:44:00.822752-04:00", "main_image": { "id": 377633, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a013900/a013906/Yarkovsky_Effect_realistic_poster.png", "filename": "Yarkovsky_Effect_realistic_poster.png", "media_type": "Image", "alt_text": "3.
