    1153 Wallenbergia, provisional designation 1924 SL, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 5 September 1924, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula. [11] The asteroid was named after German mathematician Georg Wallenberg. [2]

    Orbit and classification

    Wallenbergia is a member of the Flora family ( 402 ), a giant asteroid family and the largest family of stony asteroids in the main-belt. [3] It orbits the Sun in the inner main-belt at a distance of 1.8–2.5  AU once every 3 years and 3 months (1,189 days). Its orbit has an eccentricity of 0.16 and an inclination of 3° with respect to the ecliptic. [1]

    The body's observation arc begins with its identification as 1930 HH at Johannesburg Observatory in April 1930, almost six years after its official discovery observation at Simeiz. [11]

    Physical characteristics

    Wallenbergia has been characterized as a stony S-type asteroid by PanSTARRS photometric survey. [9]

    Rotation period

    In September 1989, the first rotational lightcurve of Wallenbergia was obtained from photometric observations by Polish astronomer Wiesław Z. Wiśniewski at University of Arizona. Lightcurve analysis gave a well-defined rotation period of 4.096 hours with a brightness amplitude of 0.33 magnitude ( U=3 ). [6] Observations in the R-band at the Palomar Transient Factory in 2014, gave a period of 4.116 and 4.12 hours with an amplitude of 0.25 and 0.23 magnitude, respectively ( U=2/2 ). [7] [8]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Wallenbergia measures 8.02 and 8.037 kilometers in diameter and its surface has an albedo of 0.37 and 0.433, respectively. [4] [5]

    The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – taken from 8 Flora, the parent body of the Flora family – and derives a diameter of 9.36 kilometers based on an absolute magnitude of 12.31. [3]

    Naming

    This minor planet was named after German mathematician Georg Wallenberg (1864–1924). The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 107 ). [2] [lower-alpha 1]

    Notes

    1. 1 2 Wallenberg's middle name is likely "Jakob", not "James" as given in the Dictionary of Minor Planet Names
