Andromeda Constellation Facts Everyone Should Know

What is Andromeda Constellation?

Andromeda Constellation is one of the constellations first listed by Ptolemy, an ancient Greco-Egyptian astronomer, in the 2nd century.

It’s the 19th largest of the 88 modern constellations of our universe.

It occupies about 722 square degrees of the sky.

The Andromeda constellation is a member of the Perseus family of constellations.

This family includes Auriga, Cetus, Perseus, Cassiopeia, Triangulum, Andromeda, and Lacerta.

Don’t mistake the Andromeda constellation with the Andromeda galaxy.

The Andromeda galaxy actually lies within the constellation.

Andromeda Constellation Reference in Mythology

The constellation is named after Andromeda, the child of Cepheus and Cassiopeia in Greek mythology.

Andromeda was famed for her beauty as well as her vanity.

Her arrogance drove her to upset the Nereids, the beautiful sea nymphs, by challenging them that her beauty is unmatched, even by them.

The Nereids complained to Poseidon. As a punishment, he decided to unleash a sea monster to destroy Cepheus’s kingdom.

Cepheus and Cassiopeia decided to chain Andromeda to a rock as a sacrifice to the monster, hoping to get their kingdom back.

Luckily, Perseus saved her and killed the sea monster. Later, they got married, and their story got documented in Greek Mythology forever.

What Does Andromeda Constellation Look Like?

Connecting the bordering stars in Andromeda, you can notice that it looks like a person chained from both hands.

This refers to the sacrificed princess, Andromeda.

This is why the constellation is referred to as “the chained lady” or “the chained woman.”

It’s also called Persea, which means “Perseus’ wife.”

The International Astronomical Union (IAU) uses the name “the chained maiden” as the English name for the Andromeda constellation.

Other names include Mulier Catenata in Latin and al-Mar’a al Musalsalah in Arabic, meaning the chained woman.

Where and When to Locate Andromeda Constellation?

The Andromeda constellation is located between latitudes +90° and -40° in the northern hemisphere, particularly in the first quadrant.

Luckily, we can locate the Andromeda constellation from both the northern and southern hemispheres of the sky.

However, it’s best viewed in the north part since it disappears in places further south -40°.

Its neighboring constellations include Pisces, Pegasus, Cassiopeia, Triangulum, and Lacerta.

If you know how to locate any of the neighboring constellations, it’ll be easier for you to find Andromeda.

Now that you know how to identify the Andromeda constellation, when is the best time to view it?
