ORION

• Orion is a eight stars constellation can be easily recognised in the night sky. It look like a warrior or hunter man.This constellation can be seen from most part of the world.Orion contains 2 of the 10 brightest stars in the night sky. The constellation of Orion’s brightest star is Rigel, which is the night sky’s 7th brightest star and represents the hunter’s left knee. Next brightest is Betelgeuse, which is the sky’s 10th brightest star and depicts the top right shoulder of Orion. All of the eight main stars in Orion, with the exception of the red super giant Betelgeuse are young blue super giants. In order of visual magnitude, Orion’s brightest stars are as follows: The brightest stars Rigel and Betelgeuse, lies at opposite corners of a quadrilateral of stars with Bellatrix and Saiph at the other corners. Inside the  quadrilateral there are three second magnitude stars. These stars form the Orion's Belt. The Sigma Orionis and  Orion nebula are a nursery of forming new stars and it lies below the Orion's belt. In sanskrit it is called Kalpurish.

• 1.Betelgeuse is a red super giant star nearing the end of its life. The end of its life is expected to result in a supernova explosion that will be highly visible from Earth, possibly outshining the Earth's moon and being visible during the day. This is most likely to occur within the next 1000 to 100,000 years.Betelgeuse is a red super giant located 642.5 light years away with a visual magnitude of 0.42. It is about 10 million years old.  In sanskrit it is called Adra meaning the moist one.
  2.Rigel is a  blue super giant that is the sixth brightest star in the night sky. Similar to Betelgeuse, Rigel is fusing heavy elements in its core and will pass its super giant stage soon, either collapsing in the case of a supernova or shedding its outer layers and turning into a white dwarf. Rigel is a triple star system 772.51 light years distant of magnitude 0.12. It is 17 times more massive than our sun, has 70 times its width, and shines 85,000 times brighter. 
  3.Bellatrix is blue giant, though it is too small to explode in a supernova. It is the closest major star in Orion at only 244.6 light years.Bellatrix  is a blue-white giant star situated 240 light years away with a visual magnitude of 1.64. It is 8 times more massive than our sun, and emits around 6,400 times more light.
  4.Mintaka is the faintest of the three stars in Orion's Belt.  It is a multiple star system, composed of a blue giant star. The Mintaka system constitutes an eclipsing binary variable star, where the eclipse of one star over the other creates a dip in brightness. Mintaka is the westernmost of the three stars of Orion's Belt, as well as the northernmost. Mintaka  is a multiple star system 900 light years distant with a visual magnitude of 2.25. Its primary components are two blue giant stars with over 20 solar masses, and 90,000 times the luminosity of our sun.
  5.Alnilam is a super giant; . It is the farthest major star in Orion at only 1,344 light years.Alnilam is a blue super giant  of magnitude 1.70. It is around 24 times bigger than our sun, and 250,000 more luminous. (Light coming from the time of Prophet Muhammad the founder of Islam and Kumar Baskar Barman great king of Assam.)
      6.Alnitak is the eastern most star in Orion's Belt. It is a triple star system, with the primary star being a hot blue super giant star in the night sky.Alnitak is a triple star system found 700 light years from our solar system that shine with a visual magnitude of 1.72. Its primary component is about 20 times bigger than our sun, and around 10,000 times more luminous.
      7.Saiph is a similar distance and size to Rigel, but appears much fainter.Saiph is a blue super giant 720 light years distant of magnitude 2.06. It has around 16 times the Sun’s mass, and shines 18,000 times brighter.It is called Ban Raja.

      

 8.Meissa is designated forms Orion's head, and is a multiple        star with a combined apparent magnitude of 3.33. Its name          means the "shining one".Saiph is a blue super giant 720 light        years distant . It has around 16 times the Sun’s mass, and               shines 18,000 times brighter.
