Lupus Constellation: The Ultimate Guide
Lupus (The wolf)
Lupus is one of the constellations located in the southern celestial hemisphere. The name of the constellation comes from Latin and means "Wolf."
The location of the constellation Lupus is essentially in the southern hemisphere, so it is impossible to visualize it in most countries in the northern hemisphere.
The constellation Lupus is a medium-sized constellation as it ranks 46th in size among the 88 constellations in the night sky.
The brightest star in the constellation Lupus is Alpha Lupi (α Lup/HD 129056) with an apparent magnitude of +2.30.
The constellation Lupus is home to deep-sky objects such as galaxies, nebulae, and star clusters.
There are no meteor showers within the boundaries of the constellation Lupus.
The Mythology And History Of The Lupus Constellation
Arabic Astronomy
In Arabic astronomy, Lupus and Centaurus were collectively referred to as "al-Shamareekh," meaning the dense branches of the date palm fruit.
Because the constellation Lupus is very faint to the eye, no culture considers it an independent constellation and therefore does not have many associated myths.
Greek Mythology
In ancient Greek culture, there is a story with which this constellation is associated; it is the myth of the king of Arcadia Lycaon. The king was transformed into a wolf as punishment for killing almost all his children in the story.
It is also often associated with the sun god Helios and another Mythical being named Bison-man, supposedly related to the Greek constellation Centaurus.
Nowadays
The International Astronomical Union named the constellation Lupus as one of the 88 officially recognized constellations worldwide during the twentieth century.
In this way, it remains with its limits intact since then, occupying an area of 334 square degrees and staying with the 46th place in size among the 88 constellations of the night sky.
The constellation Lupus is also a region teeming with deep space bodies of paramount importance to modern science and astronomy in scientific research.
How To Find The Lupus Constellation?
Visibility By Region
Lupus resides in the third quadrant of the Southern Hemisphere (SQ3) at latitudes between 35° N and 90° S, which means we can see the constellation in the night sky from all countries. The southern hemisphere of the earth and some countries of the northern hemisphere.
Lupus is visible in the Americas, Asia, Australia, and Antarctica.
Lupus is not visible in areas above 35° N latitude, such as The northern USA, Europe, Canada, and Russia.
Visibility By Season
Lupus is a constellation that can be seen most of the year in the southern hemisphere; however, June is the best month to visualize it.
The constellation Lupus is visible only during the summer in the northern hemisphere.
Finding Lupus Constellation
Lupus is near the celestial equator, so you will have to direct your gaze to the south in the northern hemisphere. You can contact the constellation Centaurus to find Lupus since both constellations are very close.
One way to locate the Lupus constellation is by finding its brightest star Alpha Lupi, which is at the end of the constellation closest to Centaurus.
The easiest way to locate the constellation Lupus is by locating Alpha Centauri, the fourth brightest star of all. Then you draw an imaginary straight line from Alpha Centauri towards the constellation Libra; in the middle of the road between the two, you will find the constellation Lupus.

Deep Sky Objects
Lupus is also known as the home of several deep-sky objects. Deep-sky objects often mean star clusters, nebulae ( interstellar cloud bodies), or galaxies.
In the case of Lupus, it is rich in galaxies, nebulae, and star clusters, one of the constellations with the most incredible diversity of deep-sky bodies.
