Hello friends continuing our journey through the constellations, today we will know the constellation of Leo, Lepus, Libra and Lupus.
Leo is one of the 48 constellations described by the 2nd-century astronomer Ptolemy, Leo remains one of the 88 modern constellations today, and one of the most easily recognizable due to its many bright stars and a distinctive shape that is reminiscent of the crouching lion it depicts. Leo contains many bright stars, many of which were identified by the ancients. There are four stars of first or second magnitude, which render this constellation especially prominent: Regulus, Beta Leonis, Gamma Leonis y Delta Leonis.

Lepus is a constellation lying just south of the celestial equator, immediately south of Orion. Its name is Latin for hare. Although the hare does not represent any particular figure in Greek mythology, Lepus was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. There are a fair number of bright stars, both single and double, in Lepus. Alpha Leporis, the brightest star of Lepus, is a white supergiant of magnitude 2.6, 1300 light-years from Earth.
