WebBennu orbits the sun every 437 days (1.20 years), coming as close as 0.90 AU and reaching as far as 1.36 AU from the sun. 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 U.S. Capitol building. The rotation of Bennu has been observed. WebGlobal geologic maps are useful tools for efficient interpretation of a planetary body, and they provide global context for the diversity and evolution of the surface. We used data …

WebFeb 9, 2024 · Bennu is a B-type asteroid, which means simply that it contains a lot of carbon, meaning that the surface reflects about four percent of the light that hits it—which isn’t a lot compared to ... WebOSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid-study and sample-return mission. The mission's primary goal is to obtain a sample of at least 60 g (2.1 oz) from 101955 Bennu, a carbonaceous near-Earth asteroid, and return the sample to Earth for a detailed analysis.

WebDec 12, 2024 · This means the site would likely allow for a pristine sample of the asteroid, giving the team insight into Bennu’s history. Although Nightingale ranks the highest of any location on Bennu, the site still poses challenges for sample collection. The original mission plan envisioned a sample site with a diameter of 164 feet (50 meters). 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. By comparison, the smallest planet, Mercury, is more than 3,000 miles across. Bennu’s average orbital distance from the Sun … See more Bennu makes one orbit around the Sun every 1.2 years. It makes one full rotation on its axis every 4.3 hours. Bennu makes a close approach to Earth every six years, although its exact distance from Earth during these … See more Close-up examinations by OSIRIS-REx revealed that Bennu’s surface is much rougher than scientists had estimated based on radar … See more Bennu likely was broken off from a much larger carbon-rich asteroid about 700 million to 2 billion years ago, which is relatively recent in … See more Bennu looks like a spinning top – a shape whose origin scientists don’t fully understand. Some other asteroids have similar equatorial ridges. In terms of its composition, because of Bennu’s resemblance to … See more WebGlobal geologic maps are useful tools for efficient interpretation of a planetary body, and they provide global context for the diversity and evolution of the surface.
