What is the star Deneb made of? WebMost stars are grouped into a small number of spectral types. The Henry Draper Catalogue and the Bright Star Catalogue list spectral types from the hottest to the coolest stars (see stellar classification). These types are designated, in order of decreasing temperature, by the letters O, B, A, F, G, K, and M. This group is supplemented by R- and N-type stars …

WebThe standard spectral class classification scheme is thus based on temperature. Most stars fit into one of the following types or spectral classes: O, B, A, F, G, K, M These classes go from hot to cool with O the hottest and M, cool. recent discoveries have led to tentative new classifications for even cooler L-class stars.

Within each class, one could find a small range of variation, and use it to define sub-classes: B0, B1, B2, down to … Webbrightest stars in the night sky and 6 th mag are the faintest stars in the night sky (or 4 or 5 if you live in a city with a bright night sky background). The stars that are hotter are bluer, and the stars that are cooler are redder. Remember that star's apparent brightness is a function of their intrinsic luminosity as well as their distance. foodbank redcar
