How 25143 Itokawa connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
The Sun and the bodies gravitationally bound to it.
Hayabusa was the first mission to return a sample from an asteroid, the near-Earth asteroid Itokawa.
The largest class of near-Earth asteroids — Earth-crossers with orbits mostly larger than Earth's, named after 1862 Apollo.
More than 1,500 microscopic grains from the S-type asteroid 25143 Itokawa, returned by Hayabusa in 2010 — the first sample ever returned from an asteroid. The grains tied ordinary (LL) chondrite meteorites to S-type asteroids and showed signs of space weathering.
Japan's Hayabusa touches down on the asteroid Itokawa; despite great difficulties it returns to Earth in 2010 with the first samples ever collected from an asteroid.
Hayabusa returned the first samples ever collected from an asteroid, from Itokawa, to Earth.
A large, dark asteroid in the outer main belt.
A near-Earth asteroid sampled by NASA's OSIRIS-REx.
The first Mars-crossing asteroid discovered — its orbit crosses that of Mars.
The largest stony (S-type) asteroid and the parent of the Eunomia family in the intermediate main belt.
The namesake of the Hilda group, whose members orbit in a 3:2 mean-motion resonance with Jupiter in the outer main belt.
A metal-rich main-belt asteroid and NASA mission target.
