Hello friends, continuing our journey through the constellations to continue learning and observe the beauty of the universe today we are going to know the constellation Crater, Cygnus, Delphinus and Draco.
Crater is a small constellation in the Southern Celestial Hemisphere. Its name means "cup" in Latin. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it depicts a cup that has been associated with the god Apollo and is perched on the back of Hydra the water snake.

Cygnus is a northern constellation lying on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. The swan is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross).

Delphinus is a constellation in the northern sky, close to the celestial equator. Its name is Latin for dolphin. Delphinus was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains among the 88 modern constellations recognized by the International Astronomical Union. Delphinus does not have any bright stars; its brightest star is of magnitude 3.8. The main asterism in Delphinus is Job's Coffin, formed from the four brightest stars: Alpha, Beta, Gamma, and Delta Delphini.
