asteroid discovered onSeptember 4 ,1972 byLyudmila Zhuravlyova . The asteroid was named in honor of Aleksandr Aleksandrovich Alekhin, a Russian-Frenchchess champion. It is a main belt asteroid with a diameter of 17.42 kilometers. [ [http://ssd.jpl.nasa.gov/sbdb.cgi#tophttp://ssd.jpl.nasa.gov/sbdb.cgi#top JPL Small-Body Database Browser ] ]The asteroid is scheduled to occlude a 9.1 magnitude star in the Leo constellation on
November 30 ,2008 , dimming the magnitude of both heavenly bodies for a maximum duration of 0.6 seconds.Astronomer s had, as of March 2008, not predicted an optimal trajectory for the event.cite web
