EQ Camelopardalis Facts

  • EQ Camelopardalis is a pulsating variable star that can be located in the constellation of Camelopardalis. The description is based on the spectral class.
  • EQ Camelopardalis is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (K5) of the star, the star's colour is orange to red .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • Using the most recent figures given by the 2007 Hipparcos data, the star is 2104.28 light years away from us. Distance

EQ Camelopardalis's Alternative Names

HIP32653 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD48547.

EQ Camelopardalis has alternative name(s) :- , EQ 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+64 602.

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

Location of EQ 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 EQ Camelopardalis, the location is 06h 48m 40.45 and +64° 45` 15.6 .

Proper Motion of EQ 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 4.56 ± 0.52 milliarcseconds/year towards the north and 4.58 ± 0.76 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 of EQ Camelopardalis

EQ Camelopardalis Colour and Temperature

Based on the star's spectral type of K5 , EQ Camelopardalis's colour and type is orange to red variable star. The star has a B-V Colour Index of 1.7 which means the star's temperature is about 3,456 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

EQ Camelopardalis Apparent and Absolute Magnitudes

EQ Camelopardalis has an apparent magnitude of 7.90 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 If you used the 2007 Parallax value, you would get an absolute magnitude of -1.15. 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 EQ Camelopardalis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.02000 which gave the calculated distance to EQ Camelopardalis as -163081.67 light years away from Earth or -50000 parsecs. If you want that in miles, it is about -958,696,043,163,156,335.43, based on 1 Ly = 5,878,625,373,183.61 miles.

In 2007, Hipparcos data was revised with a new parallax of 1.55000 which put EQ Camelopardalis at a distance of 2104.28 light years or 645.16 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 133,072,875.13 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 EQ 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.

Variable Type of EQ Camelopardalis

The star is a pulsating Semi-Regular Star w variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. EQ Camelopardalis brightness ranges from a magnitude of 8.076 to a magnitude of 7.942 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.
