    The asteroid was discovered on 9 June 1999, by the Lincoln Near-Earth Asteroid Research team at Lincoln Laboratory's ETS in Socorro, New Mexico, United States.[8] It was named for Vasiliy Fedoseev, an awardee of the ISEF contest in 2003.[2]

    Orbit and classification

    Vasifedoseev is a member of the Koronis family, a family of stony asteroids in the outer main-belt. It orbits the Sun at a distance of 2.7–3.1 AU once every 4 years and 11 months (1,807 days). Its orbit has an eccentricity of 0.08 and an inclination of 1° with respect to the ecliptic.[1] The first precovery was obtained at ESO's La Silla Observatory in 1990, extending the asteroid's observation arc by 9 years prior to its discovery.[8]

    Physical characteristics

    Rotation period

    A rotational lightcurve of Vasifedoseev was obtained from photometric observations by the wide-field survey at the Palomar Transient Factory in September 2010. Lightcurve analysis gave a rotation period of 4.1124 hours with a brightness variation of 0.23 magnitude (U=2).[6]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Vasifedoseev measures 4.9 kilometers in diameter and its surface has an albedo of 0.17,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 and calculates a diameter of 3.7 kilometers with an absolute magnitude of 14.34.[3]

    Naming

    This minor planet was named after Russian Vasiliy G. Fedoseev (born 1986) an awardee of the Intel International Science and Engineering Fair (ISEF) in 2003. At the time, he attended the Lyceum of Information Technologies Moscow, Russia.[2] The official naming citation was published by the Minor Planet Center on 14 June 2004 (M.P.C. 52172).[9]

    gollark: However, the actual `reboot` command in the sandbox does *not* reboot it fully.
    gollark: I can't get around that.
    gollark: No, it does.
    gollark: - PotatOS uses a single global process manager instance for nested potatOS instances. The ID is incremented by 1 each time a new process starts.- But each nested instance runs its own set of processes, because I never made them not do that and because without *some* of them things would break.- PotatOS has a "fast reboot" feature where, if you reboot in the sandbox, instead of *actually* rebooting the computer it just reinitializes the sandbox a bit.- For various reasons (resource exhaustion I think, mostly), if you nest it, stuff crashes a lot. This might end up causing some of the nested instances to reboot.- When they reboot, some of their processes many stay online because I never added sufficient protections against that because it never really came up.- The slowness is because each event goes to about 200 processes which then maybe do things.
    gollark: WRONG!
