Types of Constellation

constellation is a group of stars that, when drawing a line that joins them in an imaginary way, form a figure in the sky. In this way figures of people, objects or animals are formed. This type of figures in the sky was useful for navigation in ancient times, since, through these constellations, ships could guide themselves and know where they were. There are 12  major types of constellations are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces.

How many major Types of constellation are there?

The 12 constellations of the zodiac are:
  • Aries 
  • Taurus
  •  Gemini
  • Cancer
  •  Leo
  •  Virgo
  • Libra
  • Scorpius
  • Sagittarius
  • Capricornus
  • Aquarius
  • Pisces.

As we have said above, the union between the points that form a certain constellation has been (and is) arbitrary . In other words, they do not respond to a specific astronomical question, but rather to a human criterion and not referring to the stars that make up those constellations.

However, these constellations have been written down and have become part of the astronomical communication of ancient civilizations. Although the stars that form the same constellation seem to be found at a short distance, the truth is that they can be found millions of kilometers apart from each other.

Early discoveries

The ancient peoples who have observed the sky and who began to make the first notes on the constellations were the civilizations of the Middle East and those of the Mediterranean . However, and as already mentioned, since they were arbitrary in nature, many of them could correspond to constellations of a given civilization while another civilization might not recognize it as such.

Observations of the constellations

Constellations can be observed directly by looking at the night sky. However, for better observation, it is necessary to make an observation from the night sky in the countryside, since in the city, as a product of lights and environmental pollution, the luminosity of the night sky becomes opaque, avoiding seeing all the available stars in the sky.

It is also useful to obtain, previously, a map of the night sky, to locate the constellations in it. Constellations are divided into two large groups. Both are divided by their location in the sky in relation to the Ecuador line:

  • Northern constellations . They are located north of the Ecuador line.
  • Austral constellations . They are located south of the equator

The navegation

These creations have been very useful, particularly for night navigation in ancient times where the lack of technology greatly limited the orientation of navigators (except for the use of a compass).

In this way, navigators could (observing the stars and these constellations) know where they should go in order to know the destination and the route they should follow to avoid deviating.
