1909 Alekhin is an asteroid discovered on 4 September 1972 by Lyudmila Zhuravlyova. The asteroid was named in honor of Aleksandr Aleksandrovich Alekhin, a Russian-French chess champion. It is a main belt asteroid with a diameter of 17.4 kilometers.[1] It has a long 148.6 hour rotation period.[1]

The asteroid is scheduled to occlude a 9.1 magnitude star in the Leo constellation on 30 November 2008, dimming the magnitude of both heavenly bodies for a maximum duration of 0.6 seconds. Astronomers had, as of March 2008, not predicted an optimal trajectory for the event.[2]

Lyudmila Zhuravlyova is ranked number 43 in Harvard's ranking of those who discovered minor planets. She discovered 200 minor planets, thirteen of which were co-discoveries, between 1972 and 1992.[3]
