NASA demonstrates small asteroid Vesta fragments of size from five to 14 across the southern hemisphere of Bennu and from scattered legs near its center.
Boulders were detected in OSIRIS-Rex images, and it appeared much brighter than the area around the dark, rich carbon.
The team analyzed the fragments using an on-board spectrometer and found traces of the mineral pyroxene – a known compound on Vesta.
NASA theoretically this material came from the asteroid of Bennu’s parents who were hit by a piece of Vesta.

NASA demonstrates small asteroid Vesta fragments of size from five to 14 across the southern hemisphere of Bennu and from scattered legs near its center. Boulders were detected in OSIRIS-Rex images and showed much brighter from the dark, rich carbon surroundings.
Hanna Kaplan of NASA’s Goddard Space Flight Center in Grillbelt, Maryland, said: ‘Our leading hypothesis is that Bennu inherited this material from his parents’ asteroid after being hit by a vestoid (a piece from Vesta).’
‘Then, when the parent asteroid crashed destructively, a portion of its wreckage was deposited under its own gravity in Bennu, somewhat with Venta pyroxine.’
NASA has launched OSIRIS-Rex (Origins, Spectral Interpretation, Resource Identification and Security Regolith Explorer) on the asteroid Bennu in 2018 to close the object.
During spring 2019, the device spread images of odd pieces stuck in ‘piles of rubble’ that Bennu.

Daniela Delajistina of the Lunar and Planetary Laboratory at the University of Arizona in Tucson said: ‘We found six rocks scattered in the southern hemisphere of Bennu and in the equator, measuring 5 to 14 feet (about 1.5 to 4.3 meters).’
The fragments appear to be much brighter than the Bennu rocks, which NASA noted that some are ten times brighter than those around them.
Further investigation into the odd structure compounds revealed that they contained traces of the mineral pyroxene found in Vesta.
These minerals are usually formed when rocky structures melt at high temperatures and because NASA was able to refute the idea of boulders from Bennu consisting of water-bearing minerals.
Previous observations have determined that this is not unusual.
The new results help determine the complex journey of Bennu and other asteroids detected by the solar system. Based on its orbit, several studies indicate that Bennu was distributed from the interior of the main asteroid belt.
Vasa observer Don spacecraft found dark material on the hoof walls, a black boulder from the Hayabusa spacecraft in Itokawa and from the S-type asteroid in Raigut from the material observed by Hayabusa 2.
All of these discoveries suggest that “asteroids are participating in a complex orbital dance that is sometimes the result of cosmic massups,” NASA said in a statement.
As asteroids pass through the solar system, their orbits can be changed in a variety of ways, including gravitational pull from planets and other objects, meteor effects, and slight pressure from sunlight.
The new results help determine the complex journey of Bennu and other asteroids detected by the solar system.
Based on its orbit, several studies have indicated that Bennu was distributed from the interior of the original asteroid belt via a well-known gravitational path that could go from the inner main belt to Earth’s orbit near the object.

Scientists have found two major internal belt asteroid families, Polana and Yulalia which are dark and rich in carbon like Bennu.
Yulalia is the parent of a family that formed 900 to 1,500 million years ago, and Polana formed about 2 million years ago – probably not a candidate for Bennu’s parents.
Dante Loretta, chief investigator at OSIRIS-RX at the University of Arizona, said: “In addition to future studies of asteroid families, the source of Bennu must be combined with the presence of vest-like material and the apparent lack of other asteroid types.”
“We are looking forward to the return of the specimen, which is expected to contain this interesting rock type piece.”
‘The discovery of the S-type element in the asteroid Raigu made this obstacle even stronger.
‘This difference shows the value of multiple asteroid studies across the solar system.’
