12 Aurigae Star Facts
Updated : 04/02/2025
12 Aurigae is amain sequence star located in the constellation ofAuriga, The Charioteer.It is not part of the Auriga constellation outline but is within the borders of the constellation.
Based on the spectral type (B2Ve C), 12 Aurigae colour isblue, which means that the star is one of the hottest stars in theUniverse, hotter than our star.
12 Aurigae temperature is in the range of 10,000 to 30,000 Kelvin.12 Aurigae effective temperature is 8,086 Kelvin which ishotter than the Sun's effective temperature, which is 5,777 Kelvin.Based on a parallax of 1.3886, 12 Aurigae distance from Earth can be calculated at being 2,348.86 light years away or 720.15 parsecs.
Location
12 Aurigae location in sky is determined by theright ascension (R.A.) and declination (Dec.). These are equivalent to the Longitude and Latitude on Earth.The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far the star is along Earth's celestial equator. If the R.A. is positive, then it's eastwards and vice versa.
The Declination (Latitude) is how far north or south the object is compared to the celestial equator and is expressed in degrees. If the value is positive, it is north of the celestial equator. For12 Aurigae, the location is 05h 16m 27.0824322868 and +46° 24` 57.814505109 .
Based on the location of Auriga, 12 Aurigae can be located in the northern hemisphere of the celestial sky. The celestial hemisphere is equivalent to the hemispheres on Earth.12 Aurigae is north of the Ecliptic. The Ecliptic is the path that the Earth takes as it orbits the Sun. As the Earth is titled, we therefore have Celestial and Ecliptic hemispheres and they can be different for a star.
Physical Properties
Spectral Type
12 Aurigae spectral type of B2Ve Cwhich means its colour and type is blue main sequence star.There is no relationship between colour and size. For example, a red star can be large or small. Small stars are more energy efficient than larger stars and live longer.
12 Aurigae Distance from Earth
The Parallax of the star is given as 1.38860 which gives a calculated distance to 12 Aurigae of 2348.86 light years from the Earth or 720.15 parsecs. It is about 13,808,067,994,056,054 miles from Earth.The star is roughly 148,540,565.174 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
How long it will take to get to 12 Aurigae
The time it takes to travel to 12 Aurigae depends on how fast you are going. U.G. has done some calculations as to how long it will take to go at differing speeds. A note about the calculations, when I'm talking about years, I'm talking about non-leap years only (365 days).
TheNew Horizons space probe is the fastest one that we've sent into space at the time of writing. Its primary mission was to visitPluto, which at the time of launch (2006), Pluto was still a planet.
Mach 1 is the speed of sound; Mach 2 is twice the speed. |Before retiring, Concorde was the fastest commercial aeroplane and the only passenger jet that could do Mach 2.

Radial Velocity and Proper Motion
In simplistic terms, all non-rogue stars, like planets, orbit around a central object, although that is actually not true.Where is the centre of the Solar System. For simplicity it's the central star, such as the Sun. In the case of a star, it's the galactic centre. The constellations we see today will be different than they were 50,000 years ago or 50,000 years from now.
Proper motion details the movements of these stars and is measured in milliarcseconds. 12 Aurigae is moving -1.287milliarcseconds/year towards the north and -2.955milliarcseconds/year east if we saw them in the horizon.
Theradial velocity, the speed at which the 12 Aurigae istowardsthe Sun, is -32.90000 km/s. When the value is negative, the star and the Sun are getting closer to one another; likewise, a positive number means that two stars are moving away. It's nothing to fear as the stars are so far apart they won't collide in our lifetime, if ever.
