During the interval from September through early December 2005, the Hayabusa spacecraft was in close proximity to near-Earth asteroid 25143 Itokawa, and a variety of data were taken on its shape, mass, and surface topography as well as its mineralogic and elemental abundances. The asteroid's orthogonal axes are 535, 294, and 209 meters, the mass is 3.51 × 1010 kilograms, and the estimated bulk density is 1.9 ± 0.13 grams per cubic centimeter. The correspondence between the smooth areas on the… 
Itokawa – a mid-ocean ridge asteroid
Itokawa is a peanut-shaped near-Earth asteroid, c. 535 m long and c. 200 m thick (Fig. 4). Itokawa orbits the Sun between Earth and Mars, and was generally explained to have formed by the accretion
Mass and Local Topography Measurements of Itokawa by Hayabusa
TLDR
Combined with surface observations, these data indicate that Itokawa is the first subkilometer-sized small asteroid showing a rubble-pile body rather than a solid monolithic asteroid.
The nature of asteroid Itokawa revealed by Hayabusa
Abstract The spacecraft Hayabusa, which was launched in 2003, arrived at its destination, asteroid (25143) Itokawa in September 2005. The appearance of Itokawa, a small S-type near Earth asteroids,
Boulders on asteroid Toutatis as observed by Chang’e-2
TLDR
Using images acquired by the Chang’e-2 spacecraft, more than 200 boulders have been identified over the imaged area of the near-Earth asteroid Toutatis and the cumulative boulder size frequency distribution shows a steep slope, which may imply a different preservation state or diverse formation scenarios.
Space environment of an asteroid preserved on micrograins returned by the Hayabusa spacecraft
TLDR
Impact appears to be an important process shaping the exteriors of not only large planetary bodies, such as the moon, but also low-gravity bodies such as asteroids, demonstrating the central role played by impact processes in the long-term evolution of planetary bodies.
Craters, boulders and regolith of (101955) Bennu indicative of an old and dynamic surface
Small, kilometre-sized near-Earth asteroids are expected to have young and frequently refreshed surfaces for two reasons: collisional disruptions are frequent in the main asteroid belt where they
Three-Dimensional Structure of Hayabusa Samples: Origin and Evolution of Itokawa Regolith
TLDR
Regolith particles on the asteroid Itokawa were recovered by the Hayabusa mission and their three-dimensional structure and other properties, revealed by x-ray microtomography, provide information on regolith formation.

DUST LEVITATION ON ASTEROIDS
Abstract In comparison to the lunar regolith, asteroidal regoliths appear to be deficient in dust and in agglutinates, i.e., in particles ≤100 μm across. On asteroid surfaces of high electrical
Detailed Images of Asteroid 25143 Itokawa from Hayabusa
TLDR
Rendezvous of the Japanese spacecraft Hayabusa with the near-Earth asteroid 25143 Itokawa took place during the interval September through November 2005 and the onboard camera imaged the solid surface of this tiny asteroid with a spatial resolution of 70 centimeters per pixel, revealing diverse surface morphologies.
Shoemaker crater as the source of most ejecta blocks on the asteroid 433 Eros
TLDR
It is suggested that most large ejecta blocks on Eros originate from a relatively young 7.6-km-diameter crater, and a large fraction of the ejecta from impacts pre-dating that crater has apparently been buried or eroded.
Disruption of kilometre-sized asteroids by energetic collisions
Recent numerical studies suggest that ‘rubble-pile’ asteroids (gravitationally bound aggregates of collisional debris) are common in the Solar System, and that self-gravitation may equal or exceed
Impact History of Eros: Craters and Boulders
Abstract Preliminary measurements of craters and boulders have been made in various locations on Eros from images acquired during the first nine months of NEAR Shoemaker's orbital mission, including
Radar observations of asteroid 25143 Itokawa (1998 SF36)
Abstract— We observed 25143 Itokawa, the target of Japan's Hayabusa (MUSES‐C) sample‐return mission, during its 2001 close approach at Arecibo on twelve dates during March 18‐April 9 and at Goldstone
Ponded deposits on asteroid 433 Eros
Abstract— In late January 2001 the NEAR—Shoemaker spacecraft performed low‐altitude passes over the surface of 433 Eros. Coordinated observations of the asteroid surface were obtained at submeter
