The International Astronomical Union has recognized eighty-eight constellations in different sizes and shapes. Their longest is Hydra, which covers almost 1303 square degrees of the sky’s surface, while Crux is only 68 square degrees. Centaurus contains forty nine stars with apparent magnitude higher than 5, while Mensa does not include even one star of such brightness. Over the year, the Sun passes through twelve constellations of Zodiac. It should be noted that the position of bright stars is more in South than in North.
