25143 Itokawa is an Apollo and Mars-crosser asteroid discovered in 1998 by LINEAR. It is named after Hideo Itokawa, a Japanese rocket scientist.

Itokawa is believed to be an S-type asteroid in composition. It has been imaged by radar astronomy at Goldstone, revealing a somewhat elongated shape and a 12.5 hour rotation period. [1]

Itokawa is the target of the Japanese Hayabusa space probe, which will land on and take samples of the asteroid's surface in 2005.
