+4.4 Pi2 (π2) Orionis to home in on this faint galaxy, which rests just 18 arcminutes east of the star and shines at mag. Sirius is the brightest star in the sky, and the name of its parent constellation translates to «big dog,» and as legend has it, Canis Major was Orion’s faithful hunting dog. Conveniently, if you follow the line extending through Orion’s belt from your right to your left, you will soon «run into» Sirius. Procyon is also a very bright star and sits in the «little dog» off the Betelgeuse side of Orion’s upper body.
- Near Sirius and further up in the sky are the two brightest stars in Orion — the red supergiant star Betelgeuse, and Rigel, a blue supergiant star.
- +5.9, a small scope will show NGC 2169, containing 16 stars in a 5 arcsecond area.
- Security also earns high marks thanks to licensing, strict KYC verification, and encrypted payments.
- Alnitak, Zeta Orionis (ζ Ori), is the leftmost star of Orion’s Belt.
- The Abell catalogue of planetary nebulae lists 86 objects, many of which are faint and require large scopes.
Each package is designed to give a strong start, whether you prefer casino games, sports betting, or crypto play. Constellations weren’t just for telling stories in the ancient world. Because they are easily recognisable patterns, people have used the night sky for orions bet navigation when no landmarks were available.
So how does the position of Orion’s Belt correlate with the pyramids of the Giza plateau?
Winter often makes for better stargazing in general because colder air is usually less hazy, affording better views of stars, planets and more. Considering Alnilam’s size and trajectory of expansion, it is estimated to turn into a red giant and explode in the future. But there’s nothing new about it, stars explode all the time.
2.6 Navigating by the stars
We can find this red star if we draw a line connecting Orion’s Belt and extending it to the side of Mintaka. Two of these stars orbit each other and the third component orbits the pair. It only takes 5.7 days for the first two stars to orbit around one another because they are close. Since these stars orbit each other, there will be times when one passes in front of the other and covers it from our line of sight here on Earth. Orion is the most prominent constellation that is visible throughout the world.
What is special about the Orion constellation?
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. Looking at the Pole Star, if you imagine a line vertically down from the Pole Star to the horizon, this is North. Orion’s seven brightest stars form a distinctive hourglass-shaped asterism, or pattern, in the night sky. Four stars—Rigel, Betelgeuse, Bellatrix, and Saiph—form a large roughly rectangular shape, at the center of which lie the three stars of Orion’s Belt—Alnitak, Alnilam, and Mintaka.
NGC 2169
There are many interesting facts about this asterism that goes beyond time and culture, so let us dive deep into it. This theory states that – with precision and an eye to the sky, the great builders of the pyramids replicated Orion’s belt on the sands of Egypt. His vision restored by the rays of the rising sun, Orion is said to have gone to Crete to live with Artemis as a hunter. There’s plenty to see around the head of the hunter with a medium or large telescope. See if you can tick all 6 of our deep-sky objects off the list.

A fourth component, Delta Orionis B, is a 14th-magnitude star that may be related to the system, but its properties are not understood well enough to confirm this. Alnitak Aa and Alnitak Ab orbit each other with a period of 2,687.3 days. They are separated by only 35.9 milliarcseconds, corresponding to a physical distance of only 11 astronomical units (Earth-Sun distances).
- A 150mm scope shows a misty glow sprinkled with six or so individual stars.
- To prove his theory, Bauval used modern astronomical computer programs to see the position of the sky in Giza.
- Straddling the celestial equator, it is visible from almost anywhere on Earth, a prominent feature of the northern winter sky and of the southern summer sky.
- In ancient Egyptian mythology, Orion and the bright star Sirius represent Osiris and Isis.
- One of the most obvious features people see in Orion is the three starsthat make up what most people consider the belt of the giant.
That’s how far light spreads and when it finally reaches us, it appears as one bright dot. Another noticeable star you can find using Orion’s Belt is Aldebaran, a red giant star located in the constellation Taurus. To identify Aldebaran, follow Orion’s Belt in the opposite direction (from east to west) from how you identified Sirius.

The Hunter is one of the most recognizable constellations in the sky. Its major stars form a distinctive human figure in the sky that represents the Greek mythical character. Orion’s Belt is one of the most familiar asterisms in the night sky, along with the Big Dipper in the northern sky and the Southern Cross in the southern. The asterism is easy to find because is part of one of the most prominent stellar patterns in the northern sky, the hourglass-shaped constellation figure of Orion. The asterism and the constellation dominate the evening sky from November to February.
