DG Camelopardalis Facts

DG Camelopardalis's Alternative Names

HIP19764 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD26308.

DG Camelopardalis has alternative name(s) :- , DG Cam.

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+66 312.

More details on objects' alternative names can be found at Star Names .

Location of DG Camelopardalis

The location of the variable 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 DG Camelopardalis, the location is 04h 14m 15.15 and +66° 32` 52.5 .

Proper Motion of DG Camelopardalis

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 -0.52 ± 0.66 milliarcseconds/year towards the north and 0.31 ± 0.96 milliarcseconds/year east if we saw them in the horizon. . 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 (Colour, Temperature) of DG Camelopardalis

DG Camelopardalis Colour and Temperature

DG Camelopardalis has a spectral type of K5. This means the star is a orange to red variable star. The star has a B-V Colour Index of 2 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 1,830 Kelvin.

DG Camelopardalis Radius

Radius has been calculated as being 65.46 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 45,548,931.06.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 96.38. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

DG Camelopardalis Apparent and Absolute Magnitudes

DG Camelopardalis has an apparent magnitude of 8.27 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 0.76 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.08. 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 DG Camelopardalis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 3.15 which gave the calculated distance to DG Camelopardalis as 1035.44 light years away from Earth or 317.46 parsecs. If you want that in miles, it is 8,959,789,290,030,320.27.

In 2007, Hipparcos data was revised with a new parallax of 2.14 which put DG Camelopardalis at a distance of 1524.13 light years or 467.29 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 96,384,809.69 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.

Time to Travel to DG Camelopardalis

A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

If you were to drive there at about 120 m.p.h. in a car with an infinity engine so you didn't have to pull over for petrol, it would take you 50,724,698,803,410.22 hours or 5,790,490,730.98 years.

At the time of writing, the fastest probe so far created is the New Horizon probe which is travelling at a speed of 33,000 m.p.h. If the probe was travelling to DG Camelopardalis then it would take 184,453,450,194.22 hours / 21,056,329.93 years to get there. Speed Ref: N.A.S.A.

It would to take a spaceship journey travelling at the speed of light, 1035.44 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

DG Camelopardalis brightness ranges from a magnitude of 8.470 to a magnitude of 8.339 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 days (variability).

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.
