It crosses the parallel of 10º of South latitude being visible during the months of January to August, is to 40º to the south of the equator of the Milky Route but they are possible to be observed some stellar wealth as we came near to Scorpius in the Eastern zone.

  Libra limits the north with the constellations of Serpens Cauda and Virgo that also limits to him by the east, to the south with Hydra and Lupus and to the west with the constellations of Scorpius and Ophiuchus.

               Libra I located the 15 of April of 1982 at the age of 15 years from the locality of Inca, Majorca, Spain to it
