More details on objects' alternative names can be found at. VY Canis Majoris Luminosity (energy emitted) Measurements of the star's luminosity vary quite dramatically, from around 250,000 to 500,000 times as luminous as the sun. . Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The letters are allocated as the next in the list up e.g. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. The temperature was calculated using information from Morgans @ Uni.edu. [1][8], In the catalogue of stars in the Calendarium of Al Achsasi Al Mouakket, this star was designated Thanih al Adzari (ثاني ألعذاري - thaanii al-aðārii), which was translated into Latin as Secunda Virginum, meaning the second virgin. You can decline to give a name which if that is the case, the comment will be attributed to a random star. The information was obtained as of 12th Feb 2017. [11] Although they are located near each other on the celestial sphere, ο1 CMa and ο2 CMa are most likely not gravitationally bound to each other as they appear to lie many light years apart. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 10,000 and 25,000K based on the notes from Harvard University. 12 Canis Majoris Colour and Temperature Based on the star's spectral type of B7II/III, 12 Canis Majoris's colour and type is blue giant star. The source of the information if it has a Hip I.D. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. The relative brightnesses of the three spectroscopic components have been calculated from the eclipses and orbital movement. [8] It has about 21[7] times the mass of the Sun and 65[6] times the Sun's radius. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Based on the spectral type (B7II/III) of the star, the star's colour is blue . Information regarding Metallicity and/or Mass is from the E.U. VY Canis Majoris is estimated to have surface temperatures of around 3,200C (5,800F). [12] This star, along with ε CMa (Adhara), δ CMa (Wezen) and η CMa (Aludra), were Al ʽAdhārā (ألعذاري), the Virgins. The star's Galacto-Centric Distance is 7,548.00 Parsecs or 24,618.81 Light Years. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.49 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.85. GH follow GG, all the way up to ZZ then a V and a number is the next in the order. For DZ Canis Majoris, the location is 07 16 59.3295830214 and -15 18 25.436502497 . The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*. An Astronomical Unit is the distance between Earth and the Sun. For 12 Canis Majoris, the location is 06h 47m 01.49 and -21° 00` 55.5 . The time it will take to travel to this star is dependent on how fast you are going. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. In the case of a star, its the galactic centre. It should not be taken as though the star is moving closer or further away from us. The smaller the magnitude, the brighter the star. U.G. [1], This is a massive supergiant star with a stellar classification of B3 Ia,[3] indicating that, at the age of around 7 million years,[7] it has exhausted the supply of hydrogen at its core and is now undergoing nuclear fusion of helium to generate energy. It has been known to produce widely incorrect figures. 12 Canis Majoris estimated radius has been calculated as being 2.09 times bigger than the Sun. If the R.A. is positive then its eastwards. In all likelihood, it will end its life as a Type II supernova. EZ Canis Majoris Colour Based on the star's spectral type of WN5 (SB1) The star has a B-V Colour Index of -0.05 which means the star's temperature is about 11,775 Kelvin. The number of A.U. It is about 90,443,004,083,952,231 miles from Earth. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. has done some calculations as to how long it will take going at differing speeds. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. An Astronomical Unit is the distance between Earth and the Sun. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 5,000 and 6,000K based on the notes from Harvard University. When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. The temperature was calculated using information from Morgans @ … Omicron 2 Canis Majoris is one of the most luminous stars known, as it radiates about 220,000 times as much luminosity as the Sun from its outer envelope at a temperature of 15,500 K. At this heat, the star is glowing with the blue-white hue of a B-type star. There's no register feature and no need to give an email address if you don't need to. Sir John named the stars in the constellation with a number and its latin name, this star's Flamsteed designation is 12 Canis Majoris. When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 4.88000 which gave the calculated distance to 12 Canis Majoris as 668.37 light years away from Earth or 204.92 parsecs. Proper Motion details the movements of these stars and are measured in milliarcseconds. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,450,779.77.km. is the number of times that the star is from the Earth compared to the Sun. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Given this information, we can calculate the surface temperature of the star with the following equation, whereby T = temperature (the unknown), L = luminosity = 270,000 solar, and R = radius = 1480 solar: The Variable Type is usually named after the first star of that type to be spotted. The figure of 497.88 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012. has done some calculations as to how long it will take going at differing speeds. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 16.40000 km/s with an error of about 2.50 km/s . All messages will be reviewed before being displayed. The star has a B-V Colour Index of -0.15 which means the star's temperature is about 13,674 Kelvin.
