What is the Constellation Zodiac Constellation Names

Children and adults around the world love to look at the stars, connect the dots to create the shapes they were told or their shapes. But these shapes probably emerged as important tools to help people mark what time of year it was.

History of Constellations

Just like the sun, stars move in a regular chart across the sky. At different times of the year, different constellations appear at sunset. Ascendant constellations rotate according to the Earth’s movement in space and can therefore be used to mark the seasons in regions where moderate weather does not indicate the change between winter and spring.

Many constellations in the northern sky bear Greek and Roman names, but long before these empires took root, humans were mapping the sky. The Greeks adopted their system from Babylonian roots, perhaps 3000 years ago, from the Sumerian tradition. Going even further, scientists suspect that markings made 17,000 years ago on cave walls in Lascaux, southern France, may have mapped the Pleiades and Taurus star clusters and could be the first known star map.

In 1929, the International Astronomical Union (IAU) officially identified 88 constellations in the sky. However, these constellations are almost rectangular slices of the sky that are not drawn by combining certain stars, but that contain stars. Officially setting these boundaries allows astronomers to communicate with each other about which region of the sky they are studying. Within these 88 regions, there are single star groups that people know as constellations. As an example, the constellation Ursa Major includes all the stars around the shape known by the same name.

But many star groups that most people assume constellations are not officially constellations. For example, the Big Dipper within the Big Bear is not considered a constellation; instead, it is an asterism or a group of stars not officially identified but known to most non-astronomers.

Constellation Names and Zodiac Signs

As the earth rotates, the sun, moon, and planets move along a specific path in the sky known as the orbital plane. The list of 13 constellations they pass through is known as the stars of the zodiac. Zodiac constellation names:

Astrologers exclude Ophiuchus and use 12 of these constellations to predict as zodiac signs. (Unlike astronomy, astrology is not a science.) Signs are different from constellations, they just resemble each other. Pisces, for example, corresponds to the ascension of the constellation Aquarius. Ironically, if you are born under a certain sign, the constellation for which it is named is not visible at night; instead, the sun passes over it at that time of year, making it an invisible diurnal constellation.

Constellations appear to form shapes in the sky, but the stars themselves do not form shapes in space. The distance from our Earth to stars in a constellation varies, usually by tens of light-years, randomly distributing the stars across the galaxy.

How Far Are The Constellations?

The shapes we see in the sky at night are formed because we only see them in two dimensions, not taking into account the available depth.

However, with a bit of imagination, constellations can be an excellent source of entertainment. They can also help missing people find their way, and help celestial observers find planets, comets, or other phenomena through a process called star jumping. And just like in ancient times, constellations can evoke an eternal sense of wonder.
