51826 Kalpanachawla (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.

Orbit and classification

Kalpanachawla is a member the Eos family ({{small|606}}), the largest family in the outer asteroid belt consisting of nearly 10,000 asteroids.{{rp|23}} It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.3 AU once every 5 years and 5 months (1,968 days; semi-major axis of 3.07 AU). Its orbit has an eccentricity of 0.09 and an inclination of 10° with respect to the ecliptic.

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.

Physical characteristics

The asteroid's spectral type is unknown. Members of the Eos family are typically K-type asteroids.{{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 albedo of 0.160.

= 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.

Naming

This minor planet was named after Indo-American astronaut and mission specialist Kalpana Chawla, who died in the Space Shuttle Columbia disaster on 1 February 2003. The approved naming citation was published by the Minor Planet Center on 6 August 2003 ({{small|M.P.C. 49283}}). 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.
