For size comparison, that is just a bit bigger than the Empire State building in New York City. Bennu doesn’t have enough gravity to have an atmosphere. Watch later. There are 47,754 potential trajectories and launch windows to this asteroid. The asteroid’s equator is tilted by about 175 degrees, such as that its north pole is pointing “down” relative to Earth’s north pole. Approx. Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute (JHUAPL/SwRI) Explore related images: Asteroid Bennu, Asteroids, Near-Earth asteroids, Small bodies, Trans-Neptunian objects, Worlds. Bennu is about 0.5 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the Golden Gate Bridge. The rotation of Bennu has been observed. Dr. Lori Glaze Director, NASA Planetary Science Division: In terms of its composition, because of Bennu’s resemblance to carbon-rich meteorites found on Earth, scientists think the asteroid is made of some of the solar system’s oldest materials. It was last officially observed on May 15, 2018. These animations show a size comparison of the planned sample collection area before arriving at Bennu (orange), and after arriving at Bennu (blue). These materials were forged in large dying stars, including supernova explosions, long before our solar system formed. These graphics do not include audio. Bennu can be reached with a journey of 362 days. The odds of Bennu actually crash landing on Earth are relatively slim – only about one in 2,700 or 0.037 percent. Phillips Davis Because there is no atmospheric pressure, liquid water cannot exist on or under its surface. Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online. But the asteroid is a potential Earth Impactor listed on NASA’s Sentry Risk Table. Expanding water vapor, impacts by small space rocks known as meteoroids, and rocks cracking from thermal stress are all possible explanations. How Were the Trojan Asteroids Discovered and Named? The original mission plan envisioned a sample site with a diameter of 164 feet (50 m). Bennu is thought to be a “rubble pile” asteroid, meaning smaller fragments from the original large asteroid came together to form Bennu. It is a potentially hazardous object that is listed on the Sentry Risk Table with the second-highest cumulative rating on the Palermo Technical Impact Hazard Scale.

This means that its orbit is relatively close to Earth's orbit. iron, "We're looking for our own origins out there, and that's why we've gone so far to bring a bit of Bennu back." Bennu has a rough and rocky surface. It completes a rotation on its axis every 4.30 hours. NASA’s Lucy mission is one step closer to launch as L’TES – the Lucy Thermal Emission Spectrometer – has been integrated into the spacecraft. These graphics do not include audio. It is named after the Bennu, the ancient Egyptian mythological bird associated with the Sun, creation, and rebirth. What’s more, since arriving at the asteroid the OSIRIS-REx team has observed more than 300 occasions when rocky particles were ejected from the asteroid’s surface. At about one-third of a mile (half a kilometer) wide at its equator, Bennu is minuscule compared to the planets -- in fact, it is only slightly wider than the height of the Empire State Building. Both Bennu and Ryugu are classified as "spinning-top" asteroids. Close-up examinations by OSIRIS-REx revealed that Bennu’s surface is much rougher than scientists had estimated based on radar observations from Earth. 2019). Site Manager: On Oct. 20, 2020, NASA’s OSIRIS-REx spacecraft successfully descended to the surface of asteroid Bennu and collected rocky material from sample site Nightingale during its Touch-and-Go (TAG) sample collection maneuver. Bennu makes one orbit around the Sun every 1.2 years. Science Writer: Copy link. Shopping. Bennu's orbit is 0.00 AU from Earth's orbit at its closest point. Some particles escape into space, others briefly orbit the asteroid, and most fall back onto its surface after being launched. As astronomers discovered asteroids hiding in Jupiter’s Lagrange points, they began referring to them as “Trojan asteroids.”. New images taken during OSIRIS-REx's final flyover on April 7, 2021, reveal the aftermath of the spacecraft's historic encounter with the asteroid. Bennu’s average orbital distance from the Sun is about 105 million miles (168 million kilometers), which is only slightly farther than Earth’s average orbital distance of 93 million miles.​. It is roughly 500 meters (1,640 feet) in diameter and orbits the sun once every 1.2 years, or 436.604 days. Set to launch next year, the agency’s Psyche spacecraft will explore a metal-rich asteroid in the main asteroid belt between Mars and Jupiter. NASA JPL has classified Bennu as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth. Ronald Ballouz, co-lead author of the study, said, “Using computer simulations that model the impact that broke up Bennu's parent body, we show that these asteroids either formed directly as top-shapes, or achieved the shape early after their formation in the main asteroid belt.” Scientists think that a cataclysmic collision caused a carbon-rich asteroid 60 to 130 miles (100-200 kilometers) in diameter, roughly the size of Connecticut, to break apart, scattering pieces including Bennu. The asteroid has wandered into near-Earth space because of gravitational interactions with the giant planets and because of the long-term Yarkovsky effect—the small force on a spinning body due to its absorbing sunlight and re-emitting the heat as infrared radiation. Bennu does not appear to have the conditions necessary for life as we know it. Comparison of Bennu's size. The graphics on this page are available for download in broadcast resolution. The below comparison is an artistic rendering that uses available data on the diameter of Bennu to create an approximate landscape rendering with New York City in the background. The best evidence suggests that within 10 million years of our solar system’s formation, Bennu’s present-day chemistry and mineralogy were already established. Bennu has a cumulative 1-in-2,700 chance of impacting Earth between 2175 and 2199. This will make Bennu, which is only about 1,600 feet across, the smallest object ever orbited by a spacecraft. Bennu is completely covered in rocks and large boulders, some as big as 72 feet (22 meters) across. Here are the top scenarios ordered by probability of impact: Bennu's orbit is determined by observations dating back to Sept. 11, 1999. If Bennu were placed (gently) on the surface of Earth, our planet’s gravity would cause the whole structure to fall apart. See more at the NHATS Mission Trajectories table for Bennu. 85.5 million tons (77.6 million metric tons). Bennu has 15 close approaches predicted in the coming decades: NASA Sentry has assessed impact risk for 78 very close approach scenarios. By comparison, Earth’s tilt is 23 degrees, which accounts for the seasonal changes we see on our planet.
