Location of 46 Camelopardalis

The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For 46 Camelopardalis, the location is 07h 19m 52.84 and +59° 15` 10.6 .

Radial Velocity and Proper Motion of 46 Camelopardalis

Proper Motion

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that 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 are measured in milliarcseconds. The star is moving -27.04 ± 0.28 milliarcseconds/year towards the north and -12.37 ± 0.54 milliarcseconds/year east if we saw them in the horizon.

Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 8.60000 km/s with an error of about 0.20 km/s . 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. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.

Physical Properties of 46 Camelopardalis

46 Camelopardalis Colour and Temperature

Based on the star's spectral type of K2 , 46 Camelopardalis's colour and type is orange to red star. The star has a B-V Colour Index of 1.47 which means the star's temperature is about 4,076 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

46 Camelopardalis Radius

46 Camelopardalis estimated radius has been calculated as being 45.13 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 31,400,620.56.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 46.39320709239389419521449464. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures.

46 Camelopardalis Mass

The 46 Camelopardalis's solar mass is 1.70 times that of our star, the Sun. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.

46 Camelopardalis Metalicity

The star's metallicity is -0.130000, this value is the fractional amount of the star that is not Hydrogen (X) or Helium (Y). An older star would have a high metallicity whereas a new star would have a lower one.

46 Camelopardalis Apparent and Absolute Magnitudes

46 Camelopardalis has an apparent magnitude of 6.75 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -1.91 If you used the 2007 Parallax value, you would get an absolute magnitude of -1.97. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to 46 Camelopardalis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.85000 which gave the calculated distance to 46 Camelopardalis as 1763.05 light years away from Earth or 540.54 parsecs. If you want that in miles, it is about 10,364,310,464,191,363.61, based on 1 Ly = 5,878,625,373,183.61 miles.

In 2007, Hipparcos data was revised with a new parallax of 1.80000 which put 46 Camelopardalis at a distance of 1812.02 light years or 555.56 parsecs. It should not be taken as though the star is moving closer or further away from us. It is purely that the distance was recalculated.

Using the 2007 distance, the star is roughly 114,591,677.27 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.

Travel Time to 46 Camelopardalis

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
