3822 Segovia (prov. designation:1988 DP1) is a stonyFlora asteroid from the inner regions of theasteroid belt. It was discovered by Japanese astronomerTsutomu Seki atGeisei Observatory in Kōchi, Japan, on 21 February 1988.[6] The presumedS-type asteroid has arotation period of 11.0 hours and measures approximately 5 kilometers (3.1 miles) in diameter. It was later named after Spanish guitaristAndrés Segovia.[2]
TheS-type asteroid is a member of theFlora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in theinner main-belt at a distance of 2.0–2.5 AU once every 3 years and 5 months (1,249 days). Its orbit has aneccentricity of 0.12 and aninclination of 3° with respect to theecliptic.[1] It was first observed as1962 ST at theKarl Schwarzschild Observatory in 1962, extending the body'sobservation arc by 26 years prior to its official discovery observation.[6]
Thisminor planet was named for world-famous virtuoso classical guitaristAndrés Segovia (1893–1987). In 1959, the discoverer attended one of his concerts in Japan and became inspired to play the guitar.[2] Theofficial naming citation was published by theMinor Planet Center on 21 April 1989 (M.P.C. 14481).[7]
In March 2016, arotation period ofSegovia was published using data from the Lowell Photometric Database (LPD). Usinglightcurve inversion and convex shape models, as well as distributed computing power and the help of individual volunteers, a period of11.03204±0.00001 hours could be obtained for this asteroid from the LPD's sparse-in-time photometry data (U=n.a.).[4] TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 4.9 kilometers with anabsolute magnitude of 13.7.[3]
