'''Iphigenia''' ([[minor planet designation]]: '''112 Iphigenia''') is a fairly large and exceedingly dark [[main-belt]] [[asteroid]]. BasedIt upon ais classificationclassified as a [[C-type asteroid]], itand hastherefore probably has a primitive [[carbonate|carbonaceous]] composition. It was discovered by German-American astronomer [[Christian Heinrich Friedrich Peters|C. H. F. Peters]] on September 19, 1870, and named after [[Iphigenia]], thea princess sacrificed by her father in [[Greek mythology]]. The [[orbital elements]] for 112 Iphigenia were published by [[Germany|German]] astronomer [[Friedrich Tietjen]] in 1871.<ref name="Tietjen1871"/>

This body is orbiting the [[Sun]] with a [[orbital period|period]] of 3.80&nbsp;years and an [[orbital eccentricity|eccentricity]] of 0.13. The [[orbital plane]] is [[orbital inclination|inclined]] by 2.6° to the [[plane of the ecliptic]]. 112 Iphigenia has a cross-section diameter of ~72&nbsp;km. [[Photometry (astronomy)|Photometric]] observations of this asteroid during 2007 at the [[Observatorio Astronómico de Mallorca]] were used to create a [[light curve]] plot, which was published in 2010. This showed a relatively long [[Synodic period|synodic]] [[rotation period]] of {{val|31.385 ± |0.006}} hours (1.3 days) and a brightness variation of {{val|0.30 ± |0.02}} [[Magnitude (astronomy)|magnitude]] during each cycle.<ref name="Cikota2010"/> These findings agree with independent results reported in 2008, which gave a period of {{val|31.466 ± |0.001}} hours.<ref name="Pilcher2008"/>
