(51826) Kalpanachawla is an asteroid of the main belt , which was discovered on July 19, 2001 by the American astronomer Eleanor Helin , on recordings of the Near Earth Asteroid Tracking (NEAT) project, which were recorded with the 120 cm Oschin-Schmidt Telescope of the Palomar Observatory ( IAU code 644) in California .
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(51826) Kalpanachawla was named on August 6, 2003 after the American astronaut of Indian descent Kalpana Chawla , who was killed in the accident on the Columbia space shuttle on February 1, 2003. Asteroids were named after all members of the Columbia crew: after Rick Douglas Husband (51823) Rickhusband , after Michael Philip Anderson (51824) Mikeanderson , after David McDowell Brown (51825) Davidbrown , after Laurel Blair Salton Clark (51827) Laurelclark , after Ilan Ramon (51828) Ilanramon and after William Cameron McCool (51829) Williemccool .
