3822 Segovia, provisional designation 1988 DP1, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered by Japanese astronomer Tsutomu Seki at Geisei Observatory in Kōchi, Japan, on 21 February 1988.[6]

The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 5 months (1,249 days). Its orbit has an eccentricity of 0.12 and an inclination of 3° with respect to the ecliptic.[1] The first precovery was taken at the Karl Schwarzschild Observatory in 1962, extending the asteroid's observation arc by 26 years prior to its discovery.[6]

In March 2016, a rotation period was published using data from the Lowell Photometric Database (LPD). Using light-curve inversion and convex shape models, as well as distributed computing power and the help of individual volunteers, a period of 11.03204±0.00001 hours could be obtained for this asteroid from the LPD's sparse-in-time photometry data (U=n.a.).[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 4.9 kilometers, based on an absolute magnitude of 13.7.[3]

The minor planet was named for world-famous virtuoso classical guitarist Andrés Segovia (1893–1987). In 1959, the discoverer attended one of his concerts in Japan and became inspired to play the guitar.[2] Naming citation was published on 21 April 1989 (M.P.C. 14481).[7]
