'''51826 Kalpana Chawla''', provisional designation {{mp|2001 OB|34}}, is an Eoan [[asteroid]] in the outer region of the [[asteroid belt]], approximately 7 kilometers in diameter. It was discovered on 19 July 2001, by astronomers of the [[Near-Earth Asteroid Tracking]] program at [[Palomar Observatory]] in California, United States. The asteroid was named for Indo-American astronaut and mission specialist [[Kalpana Chawla]], who died in the [[Space Shuttle Columbia disaster|Space Shuttle ''Columbia'' disaster]].

== Orbit and classification ==

''Kalpanachawla'' is a member the [[Eos family]] ({{small|[[FIN tbl#606|606]]}}),<ref name="Ferret" /> the largest [[Asteroid family|family]] in the [[Kirkwood gap|outer]] asteroid belt consisting of nearly 10,000 asteroids.<ref name="Nesvorny-2014" />{{rp|23}} It orbits the Sun in the [[Kirkwood gap|outer]] asteroid belt at a distance of 2.8–3.3 [[Astronomical unit|AU]] once every 5 years and 5 months (1,968 days; [[semi-major axis]] of 3.07 AU). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.09 and an [[orbital inclination|inclination]] of 10[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" />

The body's [[observation arc]] begins with a [[precovery]] taken by [[Spacewatch]] at [[Kitt Peak Observatory]] in April 1994, more than 7 years prior to its official discovery observation at Palomar.<ref name="MPC-object" />

== Physical characteristics ==

The asteroid's [[Asteroid spectral type|spectral type]] is unknown.<ref name="jpldata" /> Members of the [[Eos family]] are typically [[K-type asteroid]]s.<ref name="Nesvorny-2014" />{{rp|23}}

=== Diameter and albedo ===

According to the survey carried out by the [[NEOWISE]] mission of NASA's [[Wide-field Infrared Survey Explorer]], ''Kalpanachawla'' measures 6.947 kilometers in diameter and its surface has an [[astronomical albedo|albedo]] of 0.160.<ref name="Masiero-2011" />

=== Rotation period ===

As of 2017, no rotational [[lightcurve]] of ''Kalpanachawla'' has been obtained from photometric observations. The asteroid's [[rotation period]], poles and shape remain unknown.<ref name="jpldata" /><ref name="lcdb" />

== Naming ==

This [[minor planet]] was named after Indo-American astronaut and mission specialist [[Kalpana Chawla]], who was killed in the [[Space Shuttle Columbia disaster|Space Shuttle ''Columbia'' disaster]] on 1 February 2003.<ref name="springer" /> The approved naming citation was published by the [[Minor Planet Center]] on 6 August 2003 ({{small|[[Minor Planet Circulars|M.P.C.]] 49283}}).<ref name="MPC-Circulars-Archive" /> The following asteroids were also named in memory of the other six members of [[STS-107]]: [[51823 Rickhusband]], [[51824 Mikeanderson]], [[51825 Davidbrown]], [[51827 Laurelclark]], [[51828 Ilanramon]] and [[51829 Williemccool]].<ref name="springer" /><ref name="wn-1" />
