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.

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.

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 has been known since antiquity and, as a component of Orion's Belt , has been of widespread cultural significance. It was reported to be a double star by amateur German astronomer George K. Kunowsky in The stellar parallax derived from observations by the Hipparcos satellite imply a distance around parsecs , but this does not take into account distortions caused by the multiple nature of the system and larger distances have been derived by many authors. Alnitak is a triple star system at the eastern end of Orion's Belt, the second-magnitude primary having a 4th-magnitude companion nearly 3 arcseconds distant, in an orbit taking over 1, years. Alnitak Aa is a blue supergiant of spectral type O9. It is estimated as being up to 33 times as massive as the Sun and a diameter 20 times greater. It is some 21, times brighter than the Sun , with a surface brightness luminance some times greater. It is the brightest star of class O in the night sky. A fourth star, 9th-magnitude Alnitak C, has not been confirmed to be part of the Aa—Ab—B group, and may simply lie along the line of sight. The Alnitak system is bathed in the nebulosity of IC The three belt stars were collectively known by many names in many cultures.

The Horsehead Nebula also known as Barnard 33 is located just to the south of Alnitak.

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.

Moreover, unlike other eye-catching constellations, Orion lies on the celestial equator. It alone stands visible throughout the world. Because the Belt stars are fairly bright at 2nd magnitude, matching Polaris and six of the seven Big Dipper stars, Orion successfully withstands most light pollution. To the ancient Sumerians, Orion was a sheep. But most cultures visualized a human. Not necessarily a hunter, of course; the starry shape would just as easily fit a vegetarian or a dental hygienist. Still, widely separated civilizations like the Greeks and the natives of Mexico called it a hunter. The Chinese, as usual, went their own way.

It is a hot blue bright giant of the spectral type O9. The Horsehead Nebula also known as Barnard 33 is located just to the south of Alnitak. They are separated by only It has the stellar classification B0 Ia, indicating a luminous blue supergiant. The asterism is sometimes more commonly known as the Three Kings or Three sisters. Navy Crater -class cargo ship named after the star. It has around It is the primary star in a triple star system located approximately 1, light-years away. The third component, Zeta Orionis B, orbits the main pair with a period 1, It is

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.

The Alnitak system is bathed in the nebulosity of IC The last two components of the Mintaka star system are much smaller. Its radius is around Navy Crater -class cargo ship named after the star. It has an apparent magnitude of 2. The name denotes a hunter. In Chinese mythology they were known as The Weighing Beam. Several smaller reflection nebulae appear near Alnilam and Mintaka. According to legend, Gaia sent a scorpion to prove him wrong. Absolute magnitude M V.
