Origin of asteroid (101955) Bennu and its connection to the New Polana family [PDF]

open access: yesScientific Reports
The asteroid (142) Polana is classified as a B-type asteroid located in the inner Main Belt. This asteroid is the parent of the New Polana family, which has been proposed to be the likely source of primitive near-Earth asteroids such as the B-type ...

Ejecta from the DART-produced active asteroid Dimorphos [PDF]

open access: yesNature, 2023
Some active asteroids have been proposed to be formed as a result of impact events^ 1 . Because active asteroids are generally discovered by chance only after their tails have fully formed, the process of how impact ejecta evolve into a tail has, to our ...

Soluble organic molecules in samples of the carbonaceous asteroid (162173) Ryugu

open access: yesScience, 2023
The Hayabusa2 spacecraft collected samples from the surface of the carbonaceous near-Earth asteroid (162173) Ryugu and brought them to Earth. The samples were expected to contain organic molecules, which record processes that occurred in the early Solar ...
