The Constellation of Cetus is not one of the 12 constellations of the Zodiac. Cetus is represented as a huge and unusual sea monster with parts of sea creatures and large forefeet.

The largest Constellation is called Hydra and the smallest Constellation is called Crux The Sun does not belong to any constellation.
A Constellation does not actually exist as a fixed object, it is a group of bright stars that happen to be in a random place and are light years apart and ever moving. We see the pattern of their presence. Red Dwarf is not a Dwarf Planet it is a Star. What is the celestial sphere? In astronomy and navigation terms, the celestial sphere is imaginary.

However, Cetus has also been variously depicted with animal heads attached to an aquatic animal body. The constellation is also represented in many non-Western astrological systems. This star has left its main sequence and is on its way to becoming a red giant. Then comes Omicron Ceti, also known as Mira, binary star consisting located approximately light years away.
This binary system consists of an oscillating variable red giant Mira A. After being recorded for the first time by David Fabricius on August 3, , Mira has since gone on to become the prototype for the Mira class of variables of which there are six or seven thousand known examples. These stars are red giants whose surfaces oscillate in such a way as to cause variations in brightness over periods ranging from 80 to more than 1, days. Cetus is also home to many Deep Sky Objects.
It has an Active Galactic Nucleus AGN which is obscured from view by intergalactic dust, but remains an active radio source. It is located approximately 52 million light years away and is seen edge-on from Earth.
Next to Messier 77, NGC is a largest member of a galaxy group — measuring , light years in diameter — that also includes NGC and several smaller irregular galaxies. It has a diameter of about , light years.
The galaxy is a known radio source. It was named after the sea monster sent by the god Neptune to devour Andromeda in Greek mythology. Andromeda was chained to a rock as a sacrifice to the monster. Cetus was turned to stone when Perseus showed the monster the head of the gorgon Medusa. Today, this constellation is also sometimes identified as a whale.
To some, it represents the whale that swallowed Jonah in the famous Bible story. Cetus contains several well-known stars. The most famous is probably Mira, the first variable star to be discovered.
