If the R.A. is positive then its eastwards. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. It is about 90,443,004,083,952,231 miles from Earth. A name is preferred even if its a random made up one by yourself. [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. [9] This star is classified as an Alpha Cygni-type variable star that undergoes periodic non-radial pulsations, which cause its brightness to cycle from magnitude +2.93 to +3.08 over a 24.44 day interval. The two letters at the start identify that the star is a variable star. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). The number of A.U. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. The star has a B-V Colour Index of -0.15 which means the star's temperature is about 13,674 Kelvin. Based on the spectral type (B7II/III) of the star, the star's colour is blue . In the case of a star, its the galactic centre. In fact, its optical neighbor, the orange supergiant ο1 Canis Majoris has a much higher likelihood of 23.1% based upon its proper motion being a closer match to the motion of the cluster. The distance to this star is roughly 2,800 light years (800 parsecs), with a 34% margin of error. The star is a rotating Alpha2 Canum Venatic variable type which means that its size changes over time. 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 star is calculated at being about 15385.06 light years away from us.
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. It has been known to produce widely incorrect figures. has done some calculations as to how long it will take going at differing speeds. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 2.46. The Variable Type is usually named after the first star of that type to be spotted. The star is a pulsating Delta Cepheid variable type which means that its size changes over time. A faint star will have a high number. τ Canis Majoris appears as a class O supergiant at a distance of 5,000 light years within the open cluster NGC 2362, but this is composed of multiple stars. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.
For DZ Canis Majoris, the location is 07 16 59.3295830214 and -15 18 25.436502497 . The relative brightnesses of the three spectroscopic components have been calculated from the eclipses and orbital movement. Sir John named the stars in the constellation with a number and its latin name, this star's Flamsteed designation is 12 Canis Majoris. The temperature was calculated using information from Morgans @ … An Astronomical Unit is the distance between Earth and the Sun. 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.
Proper Motion details the movements of these stars and are measured in milliarcseconds. The temperature was calculated using information from Morgans @ Uni.edu. The Flamsteed name can be shortened to 12 Cma. The letters are allocated as the next in the list up e.g. It is about 90,443,004,083,952,231 miles from Earth. The time it will take to travel to this star is dependent on how fast you are going. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). GH follow GG, all the way up to ZZ then a V and a number is the next in the order.
Omicron2 Canis Majoris (ο² CMa, ο² Canis Majoris) is a star in the constellation Canis Major. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. 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. The number of A.U. 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. All messages will be reviewed before being displayed. is the number of times that the star is from the Earth compared to the Sun.
Based on the star's spectral type of A2V, 17 Canis Majoris's colour and type is blue - white main sequence star. There's no register feature and no need to give an email address if you don't need to. [10], While this star lies in the field of view of the open cluster named Collinder 121, it is unlikely to be a member. It should not be taken as though the star is moving closer or further away from us. [8], Omicron2 Canis Majoris is one of the most luminous stars known, as it radiates about 220,000[6] times as much luminosity as the Sun from its outer envelope at a temperature of 15,500 K.[6] At this heat, the star is glowing with the blue-white hue of a B-type star.
You can decline to give a name which if that is the case, the comment will be attributed to a random star. Proper Motion details the movements of these stars and are measured in milliarcseconds. The source of the information if it has a Hip I.D. 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. 12 Canis Majoris has an apparent magnitude of 6.07 which is how bright we see the star from Earth. satellite operation launched in 1989 for four years. Based on the star's spectral, the stars temperature is between 5,200.00 and 6,000.00 degrees kelvin. VY Canis Majoris is surrounded by an extensive and dense asymmetric red reflection nebula with a total ejected mass of 0.2-0.4 M☉ and a temperature of 800 K based on a DUSTY model atmosphere that has been formed by material expelled from its central star. The time it will take to travel to this star is dependent on how fast you are going. U.G. EZ Canis Majoris Radius
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 . [12] This star, along with ε CMa (Adhara), δ CMa (Wezen) and η CMa (Aludra), were Al ʽAdhārā (ألعذاري), the Virgins. A name is preferred even if its a random made up one by yourself. 17 Canis Majoris Luminosity According to Wikipedia, the hypergiant star VY Canis Majoris (VY CMa) in the constellation Canis Major the Big Dog has a radius that's around 1480 solar and a luminosity of 270,000 Suns.

VY Canis Majoris Statistics The Variable Type is usually named after the first star of that type to be spotted. Using the 2007 distance, the star is roughly 49,822,916.78 Astronomical Units from the Earth/Sun give or take a few. Flamsteed designations such as 12 Canis Majoris are named after the creator, Sir John Flamsteed.
[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. The properties of the minor components of the τ CMa system are poorly known. The star is moving 1.98 milliarcseconds/year towards the north and -1.02 milliarcseconds/year east if we saw them in the horizon. Based on the spectral type (G0 D~) of the star, the star's colour is yellow .

The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator.
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. There's no register feature and no need to give an email address if you don't need to. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. [4] It is losing mass from its stellar wind at the rate of around 2 × 10−9 times the mass of the Sun per year, or the equivalent of the Sun's mass every 500 million years. Hipparcos was a E.S.A. 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. Component D has been described as having spectral type B2V, but this is uncertain. The temperature was calculated using information from Morgans @ Uni.edu. 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. [3] It has an apparent visual magnitude of 3.043,[2] making it one of the brighter members of the constellation. All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun.
