Beta Canis Majoris (β Canis Majoris, abbreviated Beta CMa, β CMa), also named Mirzam / ˈ m ɜːr z əm /, [13] is a star in the southern constellation of Canis Major, the "Great Dog", located at a distance of about 500 light-years (150 parsecs) from the Sun. [1] In the modern constellation it lies at the position of the dog's front leg.
A simple chart for classifying the main star types using Harvard classification In astronomy , stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors ...
In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is.

2. Hypothermia . Hypothermia occurs when the body temperature drops to a dangerously low level. This can happen very quickly in smaller breeds of dogs, puppies, and older dogs.
Canes Venatici (/ ˈ k eɪ n iː z v ɪ ˈ n æ t ɪ s aɪ / KAY-neez vin-AT-iss-eye) is one of the 88 constellations designated by the International Astronomical Union (IAU). It is a small northern constellation that was created by Johannes Hevelius in the 17th century.
A cool star, it has a surface temperature of around 2,900 K and a radius 234 times that of the Sun, its distance estimated at 1,444–1,450 light-years from Earth. [68] At the other extreme in size is RX J0720.4-3125 , a neutron star with a radius of around 5 km. [ 69 ] Exceedingly faint, it has an apparent magnitude of 26.6. [ 70 ]
The star is radiating this energy from its outer envelope at an effective temperature of 12,050 K, [3] giving it a blue-white hue typical of B-type stars. [19] An 'e' classification indicates that the spectrum contains emission lines , which means this is a Be star that is surrounded by a thin, circumstellar disk made of gaseous material ...
