A faint star will have a high number. Rigel / ˈ r aɪ dʒ əl /, designated β Orionis (Latinized to Beta Orionis, abbreviated Beta Ori, β Ori), is a blue supergiant star in the constellation of Orion, approximately 860 light-years (260 pc) from Earth.Rigel is the brightest and most massive component—and the eponym—of a star system of at least four stars that appear as a single blue-white point of light to the naked eye. 0.0 – 1.3), Bellatrix (Gamma Ori, mag. You can decline to give a name which if that is the case, the comment will be attributed to a random star. Saiph is most likely a  supernova candidate that will explode in the near future. The bluish-white giant has enormous energy output. All messages will be reviewed before being displayed. The map was generated using Night Vision, an awesome free application by Brian Simpson. The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. There are many open clusters, nebulas, and stars there that are best observed during the month of January. 3.31 – 3.6). Together with the brighter Rigel, Betelgeuse and Bellatrix, it outlines Orion’s familiar hourglass pattern. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet. The bright star is several times bigger than our Sun. If you need the diameter of the star, you just need to multiple the radius by 2. It is 56.881 times brighter than our sun. Saiph has an apparent magnitude of 2.07 which is how bright we see the star from Earth. Its variable/pulsating period lasts for 0.0 days (variability).

Saiph has the stellar classification B0.5 Ia, indicating a luminous supergiant star, bluish-white in colour. The star is moving -1.28 ± 0.13 milliarcseconds/year towards the north and 1.46 ± 0.22 milliarcseconds/year east if we saw them in the horizon. Saiph is located in the constellation of Orion, the celestial hunter. How to choose your telescope magnification? The red crescent shape is Barnard’s Loop. Also captured is the red supergiant Betelgeuse (top left) and the famous Belt of Orion composed of the OB stars Alnitak, Alnilam and Mintaka. Saiph brightness ranges from a magnitude of 2.021 to a magnitude of 1.986 over its variable period. It has been known to produce widely incorrect figures. Using the 2007 distance, the star is roughly 40,924,715.04 Astronomical Units from the Earth/Sun give or take a few. Saiph, also known as Kappa Orionis, is the sixth brightest star in the constellation of Orion, the celestial hunter. The star will eventually expand into a red supergiant and end its life cycle like many of its bright neighbours in Orion, in a supernova explosion. Its brightness changes slightly, varying by 0.4 magnitudes. 3.16), and Eta Orionis (mag. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. It made its closest approach to the Sun millions of years ago, when it was a very young star, coming within 56 light years.
