This star is actually the nearest in the celestial equator among the three. The Orion’s Belt looked almost the same in ancient times as it does now. In ancient Egyptian mythology, Orion and the bright star Sirius represent Osiris and Isis. Ancient Egyptians believed that the gods descended from Sirius and the Belt of Orion, and instigated the human race.
- Instead, they were described as “wise men from the East.” Because of that, Orion’s Belt is also called the Three Wise Men.
- Not much is known about the third star Alnitak B, with the exception that it is also older, at around 7 million years old.
- There is a celebration for the Three Marys in France and Italy.
- It has a radius 7.2 times solar and is 32,000 times more luminous than the Sun, with a surface temperature of 29,000 K.
- The stars were collectively known by different names in different cultures.
Constellation
The Flame Nebula (NGC 2024, Sh2-277) is an emission nebula in the constellation Orion. It lies approximately 1,350 light-years from the Earth and has an apparent magnitude of 10. It is lit by a star inside it that is 20 times the mass of the Sun and could be as bright to our eyes as the other stars in Orion’s Belt.
- Follow this line for about five times the distance between the two stars, and the next bright star you reach will be the Pole star.
- There are four splittable stars, the brightest of which is another double – though this one is too tight to resolve in amateur instruments.
- The extensive slots library, packed with titles from leading providers, combines seamlessly with a robust live dealer selection and a fully integrated betting section.
- +10.0 star embedded within it, and using a large scope reveals more stars around it.
- In late November, Orion appears to be lying on his side, with the three stars of the belt pointing upward, in the Northern Hemisphere.

With a mass 14 times that of the Sun, it is also a supernova candidate. It has a radius 7.2 times solar and is 32,000 times more luminous than the Sun, with a surface temperature of 29,000 K. Alnitak Ab is a little older than its more massive companion, with an estimated age of 7.2 million years. Alnitak forms a close binary star system with a blue subgiant with the stellar classification B1IV.
It consists of three aligned stars – Alnitak (Zeta), Alnilam (Epsilon), and Mintaka (Delta). Locating Orion’s Belt is the easiest way to learn how to find the whole constellation in the night sky. If you take a closer look, Orion’s Belt forms a diamond-like shape with Betelgeuse and Rigel stars.
NGC 2112 and Barnard’s Loop
The names “Three Kings” and the “Three Marys” are just a few of the many labels for which it has become known to people. The Big Bang Optics was started because of our love for astronomy and to help others like us find the best telescope and accessories. Built with incredible accuracy and containing many puzzling features, the true purpose of the pyramids has inspired endless speculation.

Betelgeuse is in fact the second-brightest of the stars in Orion, trailing its across-the-body comrade Rigel by a slight amount. In any case, Betelgeuse is considered the 12th-brightest star in the sky. The name means “armpit of the central one” in Arabic, implying that constellations were shared between cultures. This color is caused by a blue supergiant, Anitak A, which is the primary star of the system. It happens to be a class O supergiant – some of the brightest stars visible in the night, and it’s around 30 times as big as our sun. The brightest of these objects, the Orion Nebula (Messier 42), lies below Orion’s Belt and is part of an asterism known as Orion’s Sword.
What is special about the Orion constellation?
The name “Mary” was a common Jewish name at the time, so the names might be confused with one another. When King Herod heard about this, he became worried that someone will become a new king. He called the chief priests and scribes of his kingdom and asked them about the newborn king. The priests said that the baby is in Bethlehem of Judea, as it was in the prophecy. Upon knowing about this, King Herod called the three Wise Men and asked about the star that they were following.
Below the Orion’s Belt, there is another 3-stars-line pattern, the so-called Orion’s Sword (and sometimes scabbard). It comprises three stars – 42 Orionis, Theta Orionis, and Iota Orionis – and M42, the Orion Nebula (and Running Man Nebula above). The Hopi frequently move from place to place but they have chosen to settle down in northeastern Arizona.
Betelgeuse, a variable star, is easily distinguished by its reddish colour and is the 11th brightest star in the sky, with a magnitude of 0.6. Orion’s brightest star, Rigel, located in the hunter’s leg, has a magnitude of 0.1 and is the seventh brightest star in the sky. Open cluster NGC 2141 sits 0.8˚ north and a bit east of Mu Orionis.
Their distance to one another is another factor that makes them stand out among other stars. In total, Orion is home to 10% of the seventy brightest stars, despite covering only 1.4% of the sky. Look for the contrast in colour between most of the stars and the two which mark the join between the vertical and horizontal components of the ‘7’. orions bet This pair is double star Struve 844 and looks orange compared to the white and blue-white colour of the others. The brightest star in the top of the ‘3’ is double star Struve 848, with mag. Telescopes over 250mm may detect faint nebulosity around the cluster.
