We know that billions of stars are scattered throughout the universe, forming constellations. One constellation that stands out is Ophiuchus. Ophiuchus is one of the 88 constellations recognized by the International Astronomical Union (IAU). Its name comes from Latin and means "tamer of the serpent." It is located in the southern celestial hemisphere and extends across the celestial equator, so it can also be observed from the northern hemisphere during the summer months.
In this article we are going to tell you everything you need to know about the Ophiuchus constellation, its symbol, characteristics and much more.
Ophiuchus constellation and its symbol
Ophiuchus is a rather special constellation, as it is the only one in the zodiac that has not been officially recognized as one of the twelve traditional constellations. Despite this, its presence on the ecliptic, the apparent path of the Sun across the sky, has led some astrologers to include it in the zodiac and attribute astrological influences to it.
The Ophiuchus symbol is represented by a human figure holding a snake. This image symbolizes the legend associated with the constellation. According to Greek mythology, Ophiuchus represents Asclepius, the god of medicine and healing. Asclepius was known for his ability to bring the dead back to life, which caused concern among the Olympian gods.
Some history
In the story, Zeus, the king of the gods, decided to kill Asclepius with a thunderbolt to maintain balance between the world of the living and the dead. As a tribute to his medical skills, Asclepius was placed in the sky as the constellation Ophiuchus. The snake he holds in his hands is the symbol of medicine, associated with the staff of Asclepius, which is often depicted with a snake coiled around it.
Although Ophiuchus may not be as widely recognized as the traditional zodiac constellations, its history and symbolism make it a point of interest for both astronomers and those interested in Greek mythology and astrology. If you are interested in this topic, you can explore more about the interrelationship between astronomy and astrology.
In ancient times, the Greeks associated it with Asclepius, the demigod and founder of medicine. As the only son of Apollo and Colonus, he received medical guidance from the centaur Chiron. When Asclepius was killed by Zeus, the gods brought him back to life on the condition that he live forever in the heavens. To distinguish him from other Olympian legends, they depicted him holding two snakes. At that time, snakes were considered symbols of rebirth because of their ability to shed their skin and begin a new cycle. According to Greek mythology, this is how the constellation Ophiuchus was formed.
In the night sky, it can be located at a right ascension of 17h and a declination of 0°. Because it is close to the equator, you can see both the northern and southern hemispheres. This is especially true in late December and early January when it is at its most visible. During this time, you might also observe other related constellations such as Taurus, which has its own fascinating history.
Today the constellation is known as Ophiuchus because that is how the Romans adapted the legend into Latin. If the Greek tradition were to be followed, this constellation would actually be known as "Asclepius", the snake charmer.
The number 13 of the Zodiac
It's a faint but very large constellation in the sky, difficult to see in places with a lot of light pollution. Ophiuchus is also a sign of the zodiac. It's number 13 because it lies partly between Sagittarius and Scorpio, and the sun also passes through that sign . To establish calendars and determine the seasons, ancient astronomers recorded the constellations that were visible before sunrise and after sunset. In this way, they divided the zodiac into twelve equal parts, each of which was named after a constellation. This set is called the Zodiac because most of them bear the names of animals.
We currently know of 13 constellations (12 plus Ophiuchus), and the time the Sun spends in each varies between 6 and 38 days. It contains faint stars, but also some very interesting ones, and the most beautiful part of this constellation is the area closest to the Milky Way, where we can see stunning star clusters. One of the most interesting stars is the famous Barnard's Star, because it has a high rotation rate. In fact, it is the fastest-rotating star in the background, moving at about 10,3 arcseconds per year. It covers the apparent size of the full moon for 180 years.
Major stars in the Ophiuchus constellation
Within the constellation Ophiuchus, we can find several interesting and significant stars. One of them is Rasalhague, also known as Alpha Ophiuchi. It is the brightest star in Ophiuchus and is located approximately 47 light-years from Earth . Rasalhague is a blue-white star and belongs to spectral type A5. Its name derives from Arabic and means "head of the serpent bearer."
Another notable star in Ophiuchus is Sabik, designated as Eta Ophiuchi. Sabik is a binary star system composed of two stars very close to each other. It consists of a giant star of spectral type A1 and a subgiant star of spectral type A2. Together, they emit a bluish-white light and are located approximately 88 light-years from Earth. The name Sabik also comes from Arabic and means "previous" or "first." If you are passionate about astronomy, you can check out other constellations that are easy to observe in summer.
Barnard's Star, mentioned earlier, is a red dwarf and one of the closest stars to our solar system, at only 5.9 light-years away. It is known for its rapid movement across the sky, making it an interesting star for astronomers.
In addition to these mentioned stars, Ophiuchus is home to a large number of fainter stars, but which together contribute to the beauty and complexity of this constellation.
As you can see, Ofiuco has stood out a lot for being number 13 of the Zodiac constellations and for its beauty. I hope that with this information you can learn more about the Ophiuchus constellation, its symbol and its characteristics.
