Xi Geminorum (ξ Geminorum, abbreviated Xi Gem, ξ Gem), formally named Alzirr / ˈ æ l z ər /, is a star in the zodiac constellation of Gemini.It forms one of the four feet of the outline demarcating the Gemini twins. The orbital period is 12.632 +/- 0.002 yr, the eccentricity is 0.893 +/-0.002, and the orbital parallax is 0.0291 +/-0.0024 arcsec, or a distance of 34 pc.

Low-resolution SWP spectra and high-resolution LWR spectra of the SRc variable star TV Gem have been studied. Alhena is the traditional name of star Gamma Geminorum and it is the second brightest star in the constellation Gemini, about 109 light years from the Earth , having Apparent visual magnitude of 1.9 . Astronomical Name.

This is a list of the 300 brightest stars made using data from the Hipparcos catalogue.

Alhena B is a yellow dwarf star similar in many ways to the Sun.

Alhena has an apparent magnitude of 1.93 which is how bright we see the star from Earth.

The information on magnitudes is taken from data obtained by the Hipparcos Satellite Catalog. absolute magni-tude (M V) A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. It orbits the main white subgiant Alhena A following a highly eccentric path taking nearly thirteen years to complete.

Distance measurements are from the Observer's Handbook 2001, by The Royal Astronomical Society of Canada. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.60 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.70. Volgens parallaksmetings is dit sowat 109 ligjare van die Son af. Alhena marks the foot of the twin whose head is marked by Pollux, and marks the southwestern border of the constellation, near Orion's club. The following list contains the 100 brightest stars as seen from the earth at night. [1] They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. Apparent Magnitude.

Alhena Apparent and Absolute Magnitudes. Alhena (Gamma Geminorum) is a subgiant A star and the third brightest member of the constellation Gemini.Its Arabic name (alternatively given as Almeisan) refers to a brand on a horse or a camel. Apparent Magnitude is also known as Visual Magnitude. Alhena - γ Geminorum (gamma Geminorum) Alhena, also designated as γ Geminorum (gamma Geminorum), is a multiple hypergiant star in the constellation of Gemini.

If you used the 1997 Parallax value, you would get an absolute magnitude of -4.15 If you used the 2007 Parallax value, you would get an absolute magnitude of -4.01. Eienskappe. We determine a v sin i of 8 +/-1 km/s for the A star, which confirms that it is a slow rotator. Common Name. Volgens parallaksmetings is dit sowat 109 ligjare van die Son af. Apparent Magnitude is also known as Visual Magnitude.

New spectroscopic observations of Gamma Geminorum, a bright, 'normal' A1 IV star have resulted in an improved spectroscopic orbit.

Gamma Geminorum (Alhena) is the third brightest star is Gemini, just a 0.3 magnitudes fainter than Alpha. The stellar distances are only fairly accurate for stars well within 1000 light years. Alhena visual magnitude is 1.93, making it the 42th brightest star in the sky. This is every star brighter than magnitude 3.55.

Alhena A is seen here in the distance, though in fact the white star is the larger and more luminous of the binary pair. Alhena is the traditional name of star Gamma Geminorum and it is the second brightest star in the constellation Gemini, about 109 light years from the Earth , having Apparent visual magnitude of 1.9 . Meaning. Mebsuta Apparent and Absolute Magnitudes.

The Brightest Stars. Alhena (ook bekend as Gamma Geminorum of γ Gem) is die derde helderste ster van die sterrebeeld Tweeling.Met sy skynbare magnitude van 1,9 is dit een van die helderste sterre in die naglug en duidelik met die blote oog sigbaar. Absolute Magnitude. The star has an apparent visual magnitude of 3.35, which is bright enough for it to be seen with the naked eye. Mebsuta has an apparent magnitude of 3.06 which is how bright we see the star from Earth. The available ultraviolet spectrophotometry and UBV photometry of the system can be interpreted in terms of the blended light from a B3.5 IV star and an M1 Iab star. Absolute magnitude (M)-0,68 B-V ... Alhena (ook bekend as Gamma Geminorum of γ Gem) is die derde helderste ster van die sterrebeeld Tweeling. Met sy skynbare magnitude van 1,9 is dit een van die helderste sterre in die naglug en duidelik met die blote oog sigbaar.
