'''1140 Crimea''', provisional designation {{mpf|1929 YC}}, is a stony [[asteroid]] from the middle region of the [[asteroid belt]], approximately 28 kilometers in diameter. It was discovered on 30 December 1929, by Soviet astronomer [[Grigory Neujmin]] at [[Simeiz Observatory]] on the [[Crimean peninsula]], after which it was named.<ref name="springer" /><ref name="MPC-Crimea" />
== Orbit and classification ==
''Crimea'' is a [[S-type asteroid]] in both the [[Tholen classification|Tholen]] and [[SMASS classification|SMASS]] taxonomic scheme. It orbits the Sun at a distance of 2.5–3.1 [[Astronomical unit|AU]] once every 4 years and 7 months (1,685 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.11 and an [[orbital inclination|inclination]] of 14[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> First identified as {{mpf|A922 HA}} at Simeiz in 1922, the body's [[observation arc]] begins at [[Uccle Observatory|Uccle]] in 1935, or 16 years after its official discovery observation at Simeiz.<ref name="MPC-Crimea" />
== Lightcurves ==
In April 2005, a rotational [[lightcurve]] of ''Crimea'' was obtained by American astronomer [[Robert D. Stephens|Robert Stephens]] at Santana Observatory in California. Lightcurve analysis gave a well-defined [[rotation period]] of 9.77 hours with a brightness variation of 0.30 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=3]]}}).<ref name="Stephens-2005e" /> Photometric observations by amateur astronomers Federico Manzini and [[Pierre Antonini]] in March 2014, gave a concurring period of 9.784 hours with an amplitude of 0.23 magnitude ({{small|[[LCDB quality code|U=2]]}}).<ref name="geneva-obs" /> In addition, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue and other sources gave a period 9.7869 hours, as well as a spin axis of (12.0°, -73.0°) in [[Ecliptic coordinate system|ecliptic coordinates]] ({{small|[[LCDB quality code|U=n.a.]]}}).<ref name="Hanus-2011" />
== 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, ''Crimea'' measures between 27.75 and 29.18 kilometers in diameter, and its surface has an [[astronomical albedo|albedo]] between 0.160 and 0.177 (without preliminary results).<ref name="SIMPS" /><ref name="AKARI" /><ref name="Masiero-2014" /> The ''Collaborative Asteroid Lightcurve Link'' adopts the results obtained by IRAS, that is, an albedo of 0.1772 and a diameter of 27.75 kilometers with an [[absolute magnitude]] of 10.28.<ref name="lcdb" />
== Naming ==
This [[minor planet]] was named for the [[Crimean Peninsula]] on the northern coast of the [[Black Sea]], where the discovering Simeiz Observatory is located.<ref name="springer" /> Naming citation was first mentioned in ''[[The Names of the Minor Planets]]'' by [[Paul Herget]] in 1955 ({{small|[[Herget's discovery circumstances|H 106]]}}).<ref name="springer" />
