    827 Wolfiana, provisional designation 1916 ZW, is a Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered at Vienna Observatory on 29 August 1916, by Austrian astronomer Johann Palisa, who named it after German astronomer Max Wolf. [2] [9] The assumed stony asteroid has a rotation period of 4.0654 hours.

    Orbit and classification

    Wolfiana is a member of the Flora family ( 402 ), [3] [4] a giant asteroid family and the largest family of stony asteroids in the main belt. [10] : 23  It orbits the Sun in the inner asteroid belt at a distance of 1.9–2.6  AU once every 3 years and 5 months (1,253 days; semi-major axis of 2.27 AU). 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 official discovery observation at Vienna. [9]

    Physical characteristics

    Wolfiana is an assumed stony S-type asteroid, [3] which agrees with the overall spectral type for Florian asteroids. [10] : 23 

    Rotation period

    In September 2012, a rotational lightcurve of Wolfiana was obtained from photometric observations by American astronomers Luis Martinez, Arizona, and Frederick Pilcher at Organ Mesa Observatory ( G50 ), New Mexico. Lightcurve analysis gave a well-defined rotation period of 4.0654 hours with a brightness amplitude of 0.20 magnitude ( U=3 ), [8] refining a period of 4.0 hours previously measured in November 2009 ( U=2 ). [7]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Wolfiana measures 8.488 and 8.976 kilometers in diameter and its surface has an albedo of 0.129 and 0.1153, respectively. [5] [6]

    The Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.24 – derived from 8 Flora, the parent body of the Flora family – and calculates a diameter of 6.51 kilometers based on an absolute magnitude of 13.1. [3]

    Naming

    This minor planet was named by the discoverer in 1920 ( AN 211;441 ) after German astronomer, colleague and friend, Max Wolf (1863–1932), a professor of astronomy at Heidelberg University and founder and director of the Heidelberg-Königstuhl State Observatory, who discovered several novae, comets and 248 minor planets. [2]

    The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 82 ). Asteroid 1217 Maximiliana and the lunar crater Wolf were also named in his honor. [2]
