B-type asteroids are a relatively uncommon type of carbonaceous asteroid, falling into the wider C-group; the 'B' indicates these objects are spectrally blue. [1] In the asteroid population, B-class objects can be found in the outer asteroid belt, and also dominate the high-inclination Pallas family which includes the third-largest asteroid 2 ...

Oct 16, 2020 · Bennu is classified as a B-type asteroid, which means it contains a lot of carbon in and along with its various minerals. Bennu’s carbon content creates a surface on the asteroid that reflects about four percent of the light that hits it — and that’s not a lot.

Jan 14, 2023 · There are M-type (metallic), S-type (silicate), and C-type (carbonous) asteroids with the latter being the most common. Depending on their location, asteroids can also be classified into main-belt asteroids, trojans, and near-Earth objects.

Mar 18, 2024 · Among them, the near-Earth asteroid, known as Bennu, contains a surprising reservoir of a mineral called magnesium phosphate. These bright-white particles sprinkled in a sea of Bennu's dark rocks...

1 day ago · In October 2020, a van-sized robotic spacecraft briefly touched down on the surface of Bennu, a 525-meter-wide asteroid 320 million kilometers from Earth.

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. These types are thought to correspond to an asteroid's surface composition.

Bennu is a B-type asteroid with a ~500 meter diameter. It completes an orbit around the Sun every 436.604 days (1.2 years) and every 6 years comes very close to Earth, within 0.002 AU. These close encounters give Bennu a high probability of impacting Earth in the late 22nd century.

Scientists chose Bennu, a rare B-type asteroid, as the target of the OSIRIS-REx mission because of its composition, size, and proximity to Earth.

5 days ago · B-type asteroids such as Bennu 41, so named for their blue spectral slopes, and other small bodies that emit particles 42 have been hypothesized 43 to be fragments of extinct comets sampling a ...

B-type asteroids are relatively uncommon types of carbonaceous asteroids. B-class objects are abundant in the outer asteroid belt, and also dominate the high-inclination Pallas family which includes the second-largest asteroid 2 Pallas.
