Orion 999 A project by
Luke Steel.
Period 6 Many stories explain the constellation.
The most famous and the namesake is the story of Orion the Hunter. Orion was a hunter of giants.
The way Orion became a constellation was he was hunting a giant scorpion. In the end he killed the scorpion but, at the same time he was killed. The gods then raised Orion and the scorpion to the skies. This created the constellations Orion and Scorpio. This constellation can be found in the night sky of the Northern Hemisphere from November to February. The picture above shows Orion in January around 9:00 at night. There are five facts that I think are both the most interesting and important facts about Orion. 1. Orion contains seven main stars. They are Betelgeuse, Rigel, Bellatrix, Mintaka, Alnilam, Alnitak, and Saiph. 1. There are seven main stars that make up the Orion constellation. They are Betelgeuse, Rigel, Bellatrix, Mintaka, Alnilam, Alnitak, and Saiph. 2.The brightest star in Orion is Rigel. It has an absolute magnitude of -7.84 but, more on that later. 3. Orion can be 3. Orion is helpful in finding other stars. For example, if you extend the line made by his belt southeastward you can locate Sirius. 4. Around October 20th of every year the Orion meteor shower reaches its peak. As many as 20 meteors per hour can be seen! 5. This constellation was the inspiration for the name of the NASA Orion program and the name of the 27th Infantry Division. The logo of the NASA program was used as the background for this Prezi. There are 5 stars that I believe are the most important. They are Betelgeuse, Rigel, Saiph, Mintaka, and Bellatrix. Here are some facts about Betelgeuse.
-It is a Red Super Giant
-It appears to have a Yellow coloration
-It is 643 light years away from Earth
-It has an absolute magnitude of -6.02
-It has an apparent magnitude of -2.99
-Its solar radii is 950 Here are some facts about Rigel
-It is a Blue-White Super Giant
-It appears as Blue-White from Earth
-Rigel is 860 light years away from our planet
-Its absolute magnitude is -7.84
-It has an apparent magnitude of 0.12
-The solar radii of Rigel is 74 Listed below are some facts about Saiph.
-It is a Super Giant type star
-It has a Blue-White coloring to it
-This star is 650 light years away from our planet
-The absolute magnitude of this star is -6.1
-The apparent magnitude of this star is 2.09
-The size of Saiph is fairly big having a solar radii of 22.2 The next star that will be reviewed is Mintaka.
-This star is like many of the others is a Super Giant
-The color of this star is, like all the other, is White-Blue
-This star is incredibly far with its distance from Earth being 900 light years
-The apparent magnitude is relatively high at 2.23
-The absolute magnitude is -4.99
-The solar radii is 15.8 The final star to be reviewed is Bellatrix.
-This star, unlike all the others, is a main sequence star
-It has a White hue to it
-This star is very far away at 250 light years away from Earth
-The apparent magnitude of this star is 1.64
-The absolute magnitude of this star is varying from 1.59 to 1.64
-Bellatrix is big with a solar radii of 6 I will end the presentation by showing 3 of my resources.
