GL Ursae Majoris Facts

GL Ursae Majoris's Alternative Names

HIP48422 is the reference name for the star in the Hipparcos Star Catalogue.

GL Ursae Majoris has alternative name(s) :- , GL UMa.

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

Location of GL Ursae Majoris

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 GL Ursae Majoris, the location is 09h 52m 16.41 and +60° 16` 50.7 .

Physical Properties (Colour) of GL Ursae Majoris

GL Ursae Majoris Colour and Temperature

GL Ursae Majoris has a spectral type of K:. This means the star is a orange to red variable star.

GL Ursae Majoris Apparent and Absolute Magnitudes

GL Ursae Majoris has an apparent magnitude of 12.56 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 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 GL Ursae Majoris

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -13.36 which gave the calculated distance to GL Ursae Majoris as 0 light years away from Earth or 0 parsecs. If you want that in miles, it is 0.

GL Ursae Majoris brightness ranges from a magnitude of 12.947 to a magnitude of 12.308 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.4 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.
