    6102 Visby, provisional designation 1993 FQ25, is a stony asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 21 March 1993, during the Uppsala-ESO Survey of Asteroids and Comets (UESAC) at the ESO's La Silla Observatory site in northern Chile.[7] The asteroid is the survey's lowest numbered body among its more than 1,100 discoveries.

    The S-type asteroid orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 2 months (1,530 days). Its orbit has an eccentricity of 0.16 and an inclination of 2° with respect to the ecliptic.[1] The first precovery was taken at Palomar Observatory in 1989, extending the asteroid's observation arc by 4 years prior to its discovery.[7]

    A rotational light-curve for this asteroid was obtained from photometric observations at the Palomar Transient Factory in February 2013. It gave a rotation period of 3.28±0.01 hours with a brightness variation of 0.28 in magnitude (U=2+).[5]

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.5 kilometers in diameter and its surface has an albedo of 0.29,[4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 5.2 kilometers.[3]

    The minor planet was named after Visby, a Swedish town on the island of Gotland, known for its medieval and Hanseatic history.[2] Naming citation was published on 28 September 1999 (M.P.C. 36126).[8]
