There are 88 constellations is the sky. Example of constellations include Leo, pisces, Taurus, Andromeda, and Orion.


Constellations have fascinated human beings over the ages. Numerous folklores have been woven around these striking figures in the sky. 


Constellations are often used by people to locate stars. The stars of a constellation seem to be close to each other though in reality they are far apart. 


All the 88 constellations are not visible throughout the year. Some can only be seen during certain season depending on the Earth's annual revolution around the sun.



Constellations names:-




More constellations were named in Greek and Latin by the ancient Greeks and the Romans.


Ptolemy, the great astronomers from Egypt, named 48 of the 50 constellations known during his time.


The Constellations were generally named after animal and mythological characters. For example, the constellation Leo was named after a lion, prices after two fish, and Taurus after a bull. 


Constellations Andromeda, Cassiopeia, Origin, and Perseus were named after heroines and heroes in Greek mythology.


In the post-Copernican era, from around AD 1600 to 1800, astronomers discovered a host of new constellations.


In 1928, the International Astronomical Union (IAU) took into account 38 of the newly discovered constellations along with the 50 old constellations and named the 88 constellations that we know today.

Most of the Constellations retained their Greek and Roman names.
