Perseus Constellation: The Ultimate Guide

Perseus

Perseus is a constellation located in the northern celestial hemisphere. The constellation's name comes from Greek mythology derived from "Perseus," one of the most famous warriors of ancient Greece.

The location of the constellation Perseus is essentially in the northern hemisphere, and we can find it in the night sky during the winter.

Perseus is relatively easy to see in the night sky. It features the Alpha Persei Cluster with an apparent magnitude of 1.2, visible to the naked eye.

Perseus's brightest star is Mirfak (α Persei), with a magnitude of +1.75.

The constellation Perseus is also home to deep-sky objects such as galaxies, nebulae, and star clusters.

Also, within the constellation’s boundaries, a famous meteor shower called The Perseid occurs.

The Mythology And History Of The Perseus Constellation

Greek Mythology

In ancient Greece, Perseus was one of the most famous heroes and warriors after Heracles; Perseus was a demigod son of Zeus and Danae.

His best-known feat is when he defeated the Medusa, a creature with a human body and snakes instead of hair. Usually, the Medusa is drawn with a serpentine tail instead of legs. She also has the power to turn anyone who looks into her eyes to stone.

In the myth, Perseus manages to defeat the medusa with the help of Athena's shield, which also functioned as a mirror, so he could see the Medusa without turning into stone.

The Greeks represent Perseus holding Medusa's decapitated head, which he will later use in future adventures.

Early Modern Period

In fifteenth-century celestial maps, Perseus used to be depicted as the figure of the warrior holding the shield of Athena, the sword of Hermes, and with his right hand raised holding the head of Medusa.

In these cases, the triangle of stars Gamma Persei, Miram, and Tau Persei is the head of medusa.

On celestial maps of other regions, Perseus appears with the sword and shield without the head of a medusa. Still, its boundaries and number of stars are not modified.

Perseus remains one of the northern constellations, and its boundaries have not undergone significant modifications.

In the field of research, the constellation Perseus is located just opposite the galactic plane of the Milky Way, so it is currently a region of vast importance for the study of the evolution of the universe.

The constellation Of Perseus resides in the first quadrant of the Northern Hemisphere (NQ1), at latitudes between 35° S and 90° N, which means that we can see the constellation in the non-central sky in all countries of the northern hemisphere.

Perseus is visible in the US, Europe, Russia, Asia, China, and Japan in the northern hemisphere.

Perseus is visible in all countries in the south. The only exception is New Zealand, Antarctica, and the southernmost areas of Australia, such as Tasmania, areas south of Argentina such as El Mar Del Plata, and regions south of Chile.

Visibility By Season

Perseus is a constellation into the north pole; in the northern hemisphere, it is visible during winter and in the southern hemisphere during summer.

Only a part of the constellation is seen in winter for the southern hemisphere countries. The best month to see the constellation of Perseus is in December.

To locate the constellation Perseus, you must look to the north of the celestial vault.

Perseus is huge and has one of the brightest stars in the sky, Mirfak, with a magnitude of +1.89.

You can also guide yourself using the Pleiades cluster of the constellation Taurus; this cluster is very bright and easy to find.

Draw a line from the Pleiades to the constellation Cassiopeia. You can find the constellation of Perseus right in the middle. The constellation Cassiopeia is M-shaped and is adjacent to Perseus.

Perseus is also home to several deep-sky objects. Deep-sky objects are celestial bodies different from stars, such as nebulae (body of interstellar clouds) or galaxies.

In the case of Perseus, it is very rich in planetary nebulae and galaxies; some of them are:

  • h + χ Persei,  a star formation consists of two open clusters, NGC 869  and  NGC 884.
  • M34, a star cluster with an apparent magnitude of 5.5.
  • M76, planetary nebula.
  • NGC 1499, California Nebula.
  • NGC 1333, reflection nebula.
  • NGC 1023, lenticular galaxy.

  • 0402+379, Radiogalaxy.

Meteor Showers

The constellation Perseus has an associated meteor shower called "The Perseid."

The Perseid meteor shower occurs between July 23 to August 22 and has its observation peak from August 11 to August 13.

Research suggests that the Perseid shower originates from fragments left by Comet Swift-Tuttle.
