    63305 Bobkepple (provisional designation 2001 FE) is a carbonaceous Hygiean asteroid from the outer regions of the asteroid belt, approximately 6 kilometers (3.7 miles) in diameter. It was discovered on 17 March 2001, by astronomer David Healy at the Junk Bond Observatory in Arizona, United States. [5] The asteroid was named after Bob Kepple, co-author of The Night Sky Observer's Guide.

    Orbit and classification

    Bobkepple is a member of the Hygiea family ( 601 ), [3] a large family of carbonaceous outer-belt asteroids, named after 10 Hygiea, the main belt's fourth-largest asteroid. [6] It orbits the Sun in the outer main-belt at a distance of 2.7–3.7  AU once every 5 years and 9 months (2,091 days). Its orbit has an eccentricity of 0.15 and an inclination of 6° with respect to the ecliptic. [1]

    The body's observation arc begins with a precovery image taken by Spacewatch in March 1995, six years prior to its official discovery observation at Junk Bond Observatory. [5]

    Physical characteristics

    Rotation period

    As of 2017, no rotational lightcurve of Bobkepple has been obtained from photometric observations. The asteroid's rotation period, spin axis and shape remains unknown. [1]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Bobkepple measures 6.216 kilometers in diameter and its surface has an albedo of 0.055. [4]

    Naming

    This minor planet was named after deep-sky astronomer George Robert Kepple, creator of the "Astro Cards" observing aids and co-author of The Night Sky Observer's Guide, popular among deep-sky observers. [2] The official naming citation was published by the Minor Planet Center on 4 May 2004 ( M.P.C. 51982). [7]
