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.

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.

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. Orion was unable to defeat the scorpion and met his end after being stung by it. The gods placed them both into the heavens as constellations. Orion and Scorpius are never seen in the sky at the same time. Orion is best seen during the northern hemisphere winter, while Scorpius is prominent in the summer sky, when Orion stays below the horizon.

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 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. Alnitak Aa is estimated to be up to 28 times as massive as the Sun and have a diameter 20 times greater. It is the brightest star of class O in the night sky. It is the 29th-brightest star in the sky and the fourth-brightest in Orion.

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.
