'''1296 Andrée''', provisional designation {{mp|1933 WE}}, is a stony Nysian [[asteroid]] from the inner regions of the [[asteroid belt]], approximately 25 kilometers in diameter. It was discovered on 25 November 1933, by French astronomer [[Louis Boyer (astronomer)|Louis Boyer]] at the North African [[Algiers Observatory]], Algeria, and named after the discoverer's niece.<ref name="springer" /><ref name="MPC-Andree" />
== Orbit and classification ==
''Andrée'' is a member of the [[Nysa family]], named after its namesake [[44 Nysa]] and one of the smaller asteroid families in the main-belt. It orbits the Sun at a distance of 2.1–2.8 [[Astronomical unit|AU]] once every 3 years and 9 months (1,373 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.14 and an [[orbital inclination|inclination]] of 4[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> It was first identified as {{mp|1925 TA}} at [[Heidelberg Observatory]] in 1925, extending the body's [[observation arc]] by 8 years prior to its official discovery observation.<ref name="MPC-Andree" />
== Lightcurves ==
In January 2002, a rotational [[lightcurve]] of ''Andrée'' was obtained from photometric observations by French amateur astronomer [[Laurent Bernasconi]]. Lightcurve analysis gave a well-defined [[rotation period]] of 5.178 hours with a brightness variation of 0.27 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=3]]}}).<ref name="geneva-obs" /> In October 2004, a concurring lightcurve with a period of 5.18366 hours and an amplitude of 0.23 was obtained by French astronomers [[Cyril Cavadore]] and [[Pierre Antonini]] ({{small|[[LCDB quality code|U=3]]}}).<ref name="geneva-obs" />
== Diameter and albedo ==
According to the surveys carried out by the Infrared Astronomical Satellite [[IRAS]], the Japanese [[Akari (satellite)|Akari]] satellite, and NASA's [[Wide-field Infrared Survey Explorer]] with its subsequent [[NEOWISE]] mission, ''Andrée'' measures between 20.66 and 28.045 kilometers in diameter, and its surface has an [[astronomical albedo|albedo]] of between 0.06 and 0.121.<ref name="Nugent-2016" /><ref name="Nugent-2015" /><ref name="SIMPS" /><ref name="AKARI" /><ref name="Masiero-2014" /><ref name="WISE" /> The ''Collaborative Asteroid Lightcurve Link'' derives an albedo of 0.0849 and a diameter of 25.07 kilometers with an [[absolute magnitude]] of 11.3.<ref name="lcdb" />
== Naming ==
This [[minor planet]] was named by the discoverer in honor of his niece, Andrée. Naming citation was first published by [[Paul Herget]] in ''[[The Names of the Minor Planets]]'' in 1955 ({{small|[[Herget's discovery circumstances|H 118]]}}).<ref name="springer" />
