Zodiac Constellations

People have been interested in how the universe is organized since ancient times. Long before the telescope was invented, astronomers observed the movement of celestial objects. They tried to understand the behaviour of stars, planets, the Sun and the Moon. Over time, the attention received by different objects in the sky only increased. People started to give names to the stars and grouped them into patterns that typically represent animals, mythological characters, or inanimate objects.

Almost a hundred years ago, the International Astronomical Union drew up the modern list of 88 constellations. However, without any doubt, the most well-known ones are the zodiac constellations, familiar to most people due to their application in astrology. Go on reading to find out everything you wanted to know about the constellations of the zodiac.

What Are the 12 Signs of the Zodiac?

Before we go any further, it’s a good idea to have a clear picture of what zodiac is. The word “zodiac” comes from the Greek language and means “the circle of small animals". Fair enough, as almost all the constellations of the zodiac (except Libra) represent living beings.

In astronomy, the zodiac is the name of the celestial zone around the ecliptic — the trajectory of the Sun across the sky as seen from Earth. Although the Sun actually passes through 13 constellations, in Western astrology, there are twelve signs of the zodiac. So what are the 12 signs of the zodiac? Here’s the list:

  • Aries
  • Taurus
  • Gemini
  • Cancer
  • Leo
  • Virgo
  • Libra
  • Scorpio
  • Sagittarius
  • Capricorn
  • Aquarius
  • Pisces

The Zodiac Constellation Names Origin

The names of the constellation zodiac signs have Latin origin: Aries means “ram”, Taurus — “bull”, Gemini — “twins”, Cancer — “crab”, Leo — “lion”, Virgo — “maiden”, Libra — “scales”, Scorpio — “scorpion”, Sagittarius — “archer”, Capricorn — “mountain goat”, Aquarius — “water-bearer”, Pisces — “fish”. They got their names based on creatures or objects the star patterns resemble.

12 Constellations of the Zodiac

Aries

Aries

Let’s start with the mighty Aries, which occupies the first position in the sequence of the zodiac. The traditional Western zodiac associates the Ram with the period between March 20 and April 21.

It is a mid-sized constellation, ranking 39th overall size. The highest-magnitude star of Aries is called Hamal.

Taurus

Taurus

Now it’s time to explore Taurus, number two in the modern zodiac, a constellation transited by the Sun from around April 21 until May 20.

Taurus is the 17th largest constellation in the sky. Its brightest star is Aldebaran, the 14th brightest star in the sky. Taurus is an interesting constellation, as it’s home to two open star clusters that we can see with the naked eye: the Pleiades and the Hyades.

Gemini

Gemini

Gemini is number three zodiac sign. Under the tropical zodiac, the Sun goes through it between about May 21 to June 21. Ancient Greeks associated it with the myth about Castor and Pollux.
