Characteristics
Lepus, is precious constellation located to the south or the feet of Orion and therefore quite easy to identify in winter skies of the North hemisphere and the warm summery nights of the South hemisphere. It crosses the parallel of 20º of South latitude and one is to 20º to the south of the equator of the Milky Route. She is rich in shining stars and globular accumulations. It has square dimensions of 270º.
Lepus limits the north with the constellations of Orion and Monoceros, to the east with Eridianus, the south with the constellations of Caelum and Columba and to the west with Canis Major.
Lepus I located the 14 of December of 1981 at the age of 14 years from the locality of Inca, Majorca, Spain to it.
