||1990: Lothar Collatz dies ... mathematician.
||1996: Geoffrey Wilkinson dies ... chemist and academic, Nobel Prize laureate ... who pioneered inorganic chemistry and homogeneous transition metal catalysis. Pic.


||1998: Asteroid 25143 Itokawa discovered ... a sub-kilometer near-Earth object of the Apollo group and a potentially hazardous asteroid. It was discovered by the LINEAR program in 1998 and later named after Hideo Itokawa. The strange peanut-shaped S-type asteroid has a rotation period of 12.1 hours and measures approximately 330 meters (1,100 feet) in diameter. Due to its low density and high porosity, Itokawa is considered to be a rubble pile, consisting of numerous boulders of different sizes rather than of a single solid body. It was the first asteroid to be the target of a sample return mission, the Japanese Hayabusa space probe, which recovered more than 1500 particles. It is the smallest asteroid ever photographed and visited by a spacecraft. Pic (cool).
