Mythology of Lepus

        Lepus or the hare represents the hunting animal that hunts Orión with the aid of its dogs (Canis Major and Canis Minor). It was put in the firmament by Hermes due to his great fecundity and speed.

 

ori.gif (1448 bytes) 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.

 

Constellation of Lepus

 

Main stars

       Alpha, a; denominated Arneb, of magnitude 2.59 and yellow color one is in the center of the constellation. Dista 1280 years Earth light, is a supergiant 12000 times more shining than the Sun.

      Beta, b; denominated Nibal, of magnitude 2.84 and yellow one is to 3º to the south of a, dista 159 years Earth light, and is a star 150 times more shining than the Sun.

      Gamma, g; of 3.60 magnitude and yellow color one is in the western sector of the constellation. It is a star next to the Sun of the solar type that is to 29 years light of us.

       Delta, d; of 3.78 magnitude and orange color. Dista 112 years Earth light and is 30 times more luminous than our Sun is to 2º to the west of g lepi. 

    Other objects
