'''1281 Jeanne''' (''prov. designation'': {{mp|1933 QJ}}) is a dark asteroid from the background population of the intermediate asteroid belt. It was discovered on 25 August 1933, by astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, who named it after his daughter, Jeanne.<ref name="springer" /><ref name="MPC-object" /> The likely P-type asteroid has a rotation period of 15.2 hours and measures approximately {{convert|22|km|mi|abbr=off|sigfig=2|sp=us}} in diameter.

== Orbit and classification ==

''Jeanne'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.<ref name="AstDys-object" /> It orbits the Sun in the central asteroid belt at a distance of 2.0–3.1&nbsp;AU once every 4 years and 1 month (1,492 days; semi-major axis of 2.56&nbsp;AU). Its orbit has an eccentricity of 0.21 and an inclination of 7° with respect to the ecliptic.<ref name="jpldata" /> The asteroid was first identified in July 1904, as {{mp|A904 NA}} at Heidelberg Observatory, where the body's observation arc begins in September 1929, almost four years prior to its official discovery observation at Uccle.<ref name="MPC-object" />

== Naming ==

This minor planet was named after Jeanne Arend, daughter of Belgian discoverer Sylvain Arend.<ref name="springer" /> The official naming citation was mentioned in ''The Names of the Minor Planets'' by Paul Herget in 1955 ({{small|H 117}}).<ref name="springer" />

== Physical characteristics ==

''Jeanne'' has been characterized as both an X-type and P-type asteroid by the Wide-field Infrared Survey Explorer (WISE) and Pan-STARRS photometric survey, respectively.<ref name="WISE" /><ref name="Veres-2015" />

=== Rotation period and poles ===

In May 2002, a rotational lightcurve of ''Jeanne'' was obtained from photometric observations by French amateur astronomer Christophe Demeautis. Lightcurve analysis gave a rotation period of 15.18 hours with a brightness amplitude of 0.45 magnitude ({{small|U=2}}).<ref name="geneva-obs" /> A lightcurve was also modeled using photometric data from the Lowell Photometric Database. It gave a concurring sidereal period of {{val|15.30379|0.00001}} hours and two spin axes at (153.0°, 19°) and (338.0°, 32.0°) in ecliptic coordinates (λ, β).<ref name="Durech-2016" />

=== Diameter and albedo ===

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, ''Jeanne'' measures between 14.26 and 27.620 kilometers in diameter and its surface has an albedo between 0.053 and 0.17.<ref name="Nugent-2016" /><ref name="SIMPS" /><ref name="Nugent-2015" /><ref name="AKARI" /><ref name="Masiero-2014" /><ref name="WISE" /> The ''Collaborative Asteroid Lightcurve Link'' derives an albedo of 0.0863 and a diameter of 21.65 kilometers based on an absolute magnitude of 11.6.<ref name="lcdb" />
