Dec 20, 2024 · 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, coming within about 186,000 miles (299,000 kilometers) of our planet. Its orbital path is tilted about 5 degrees relative to Earth’s.

101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the third highest cumulative rating on the Palermo Technical Impact Hazard Scale . [ 9 ]

Dec 3, 2018 · This series of images taken by the OSIRIS-REx spacecraft shows asteroid Bennu in one full rotation from about 50 miles (80 km). The spacecraft’s PolyCam camera obtained the thirty-six 2.2-millisecond frames over a period of four hours and 18 minutes.

Bennu 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.

Nov 21, 2024 · This series of images taken by the OSIRIS-REx spacecraft shows asteroid Bennu in one full rotation from about 50 miles (80 km). The spacecraft’s PolyCam camera obtained the thirty-six 2.2-millisecond frames over a period of four hours and 18 minutes.

Jan 24, 2025 · RUSSELL GRAPHIC 1 This series of images taken by the OSIRIS-REx spacecraft shows Bennu in one full rotation from a distance of around 50 miles (80 km). The spacecraft’s PolyCam camera obtained the thirty-six 2.2-millisecond frames over a period of four hours and 18 minutes. ... A hot water extract from an asteroid Bennu sample (left, “Bennu ...

Nov 25, 2018 · This series of images taken by the OSIRIS-REx spacecraft shows Bennu in one full rotation from a distance of around 50 miles (80 km). The spacecraft’s PolyCam camera obtained the 36 2.2-millisecond frames over a period of four hours and 18 minutes.

Mar 12, 2019 · The new research finds the asteroid’s rotation is speeding up by about 1 second per century. In other words, Bennu’s rotation period is getting shorter by about 1 second every 100 years.

Mar 19, 2019 · The uneven heating and cooling of Bennu as it rotates in sunlight is causing the asteroid to increase its rotation speed. As a result, Bennu's rotation period is decreasing by about one second every 100 years.

Oct 8, 2020 · As Bennu’s rotation decelerates, a highly detailed view of the asteroid is revealed using 20cm terrain elevation data (OLA) and high resolution imagery (PolyCam). The camera then zooms in and flys over several locations - Simurgh, Roc, Gargoyle, and Ocypete.
