(162173) Ryugu is a near-Earth C-type (i.e., carbonaceous) asteroid. It has been, after Itokawa, the second target for an asteroidal sample return, thanks to the JAXA Hayabusa2 mission (Watanabe et al. 2019). Most interestingly, Ryugu in situ observations in 2018–2019 have confirmed, as expected from its classification, the presence of significant ...

(101955) Bennu is a near-Earth carbonaceous asteroid, suggested to belong to the taxonomic class B or more likely to the rare class F (Belskaya et al. 2005) from its spectro-polarimetric properties (Cellino et al. 2018). It has been the target of the NASA OSIRIS-REx sample return mission, which rendezvoused with it in late 2018 and collected samples in

Asteroid Fragmentation and Evolution of Asteroids
Annual Review of Earth and Planetary Sciences, 2000To understand the complex collisional history of asteroids and explain their observed characteristics, it is necessary to be able to describe the fundamental physics of large-scale impact events. Because data collected on collisional outcomes is derived from small-scale laboratory experiments, success at describing asteroid evolution hinges ...

Itokawa (25143) is a near-Earth stony (S-type) asteroid. This object has been the first asteroidal target for a sample return mission, the JAXA Hayabusa mission. Itokawa is likely a contact binary. It is small (major axes 530 m, 290 m, and 210 m) and has a rotation period of about 12.13 h.

Icarus, 1995
Abstract Asteroid 2953 Vysheslavia, a Koronis family member about 15 km in diameter, very close to the outer edge of the 5/2 Kirkwood gap, has been shown by numerical integrations to fall into the resonance; then it approaches Jupiter and ends up into a hyperbolic orbit. The typical dynamical lifetime is of the order of 10 Myr.

The article analyzes existing information on clinical and experimental studies of vitreous changes in asteroid hyalosis, historical aspects of how this condition was studied over the past hundred years, its occurrence and pathogenesis. Results of various studies were used to evaluate current understanding of the forms and elemental composition of ...

"We are now on the threshold of a new era of asteroid studies," wrote Tom Gehrels in 1971 (Gehrels, 1971). These words proved quite prophetic for the three decades of physical observations and theoretical understanding that followed. As the third century of asteroid research has begun in 2001, we can once again picture ourselves standing on a new ...

Gut, 2010
During transarterial embolisation of a patient with hepatocellular carcinoma (HCC), a medical student learnt during his bedside teaching lesson that haematogenous metastasis may occur in cases with HCC. After this interventional procedure the medical student saw the catheter that had been used. This prompted him to use microscopy to analyse a …

Collisions of Asteroids: Asteroid (596) Sheila
Astrophysical Bulletin, 2019Among the small bodies of the Solar System, at present, a group of bodies, called comets of the main belt, exhibiting dynamic and/or physical properties of both comets and asteroids is distinguished. One of the reasons for such manifestations may be collisions with other bodies.
