Alnitak alnilam mintaka

Alnitak is a triple star system in the constellation of Orion. The system is located at a distance of several hundred parsecs from the Sun and is one of the three main stars of Orion's Belt along with Alnilam and Mintaka. The stars are members of the Orion OB1 association and the Collinder 70 [ de ] association, alnitak alnilam mintaka.

The asterism consists of three bright stars Alnitak, Alnilam, and Mintaka. The asterism is sometimes more commonly known as the Three Kings or Three sisters. It is a direct reference to the biblical tale of the three kings who offered gifts to the baby Christ. This asterism, which is among the brightest and most prominent asterisms in the winter sky, is often used to find the Orion constellation. In Chinese mythology, they were known as The Weighing Beam. Alnitak B is a 4 th -magnitude B-type star which orbits Alnitak A once every 1.

The three bright blue stars — Alnitak, Alnilam, and Mintaka — outline the belt in the constellation figure of the celestial Hunter. 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. The color picture was composited from digitized black and white photographic plates recorded through red and blue astronomical filters, with a computer synthesized green channel. The plates were taken using the Samuel Oschin Telescope, a wide-field survey instrument at Palomar Observatory, between and 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. The constellation figure of Orion, image: Stellarium. Orion is one of the oldest constellations in the sky. In Greek mythology, it represents the giant huntsman Orion, who incurred the wrath of the goddess Gaia by saying that he would hunt down every animal on Earth. According to legend, Gaia sent a scorpion to prove him wrong.

It consists of three bright stars. They are Alnitak , Alnilam and Mintaka. Looking for Orion's Belt is the easiest way to locate Orion in the night sky. The stars are more or less evenly spaced in a nearly straight line, and so can be visualized as the belt of the eponymous hunter 's clothing. The names of the three stars that comprise the Orion constellation come from Arabic. Alnitak B is a 4th-magnitude B-type star which orbits Alnitak A every 1, years. The primary Alnitak A is itself a close binary, comprising Alnitak Aa a blue supergiant of spectral type O9.

It lies at an approximate distance of 1, light years from Earth in the constellation Orion. Alnitak is the 5th brightest star in Orion and the 31st brightest star in the sky. It shares the 31s place with Alioth , the brightest star in Ursa Major. Zeta Orionis is a multiple star system with at least three components. Alnitak Aa, the primary star in the Zeta Orionis system, is a hot blue supergiant with the stellar classification O9. It is the brightest class O star in the sky. The star has a visual magnitude of 2. Alnitak Ab has the spectral classification of B1IV, indicating a blue subgiant star.

Even though Alnilam is the most distant of the three stars, it appears the brightest because it is the most massive and therefore the most intrinsically luminous of the Belt stars. One of the pyramids is exactly half as tall as the Great Pyramid of Giza. It is estimated that Alnilam will turn into a red supergiant and explode within the next million years. The stars located in the belt are one of the most famous asterisms in Western culture. The pyramids are believed to be 4, years old. The stars which appear to "hang" off the belt form an asterism called Kalevanmiekka Kaleva 's sword. Orion is one of the 15 equatorial constellations. The primary Alnitak A is itself a close binary, comprising Alnitak Aa a blue supergiant of spectral type O9. M78 is found at the intersection of the imaginary lines connecting Alnitak and Betelgeuse and Bellatrix and Sirius. The exact dates depend on the tribe and geography. The pulsations cause the brightness to vary by about 0. This is the only time of year during which it is invisible. To the bottom right is the star Rigel.

Alnilam is the central star of Orion's Belt in the equatorial constellation of Orion. This is a massive, blue supergiant star some 2, light-years distant. It is estimated to be , times as luminous as the Sun , and

Some historians believe that this is not coincidental because the structure had an astronomical purpose. They are separated by only Alnitak is a hot blue supergiant of the spectral type O9.
