Asteroid Itokawa Had Violent Past, Planetary Researchers Say
Oct 26, 2017 by Enrico de Lazaro
Asteroid 25143 Itokawa is a near-Earth, rubble-pile asteroid, measuring 535 m x 294 m x 209 m.
It was discovered in 1998 by astronomers with the LINEAR project and, seven years later, became the first asteroid from which samples were captured and brought to Earth for analysis.
Japan Aerospace Exploration Agency’s Hayabusa spacecraft touched down twice on Itokawa and collected a small amount of dust. It delivered about 1,500 dust particles to Earth in 2010.
