11836 Eileen           Discovered 1986 Feb. 5 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Eileen Collins (b. 1956), astronaut, became in Feb. 1995 the first woman to pilot a shuttle mission. In July 1999 she became NASA's first female shuttle commander. Her five-day mission launched the Chandra X-ray Telescope into orbit.
