December Constellations


December is typically a month that is filled with various holiday celebrations; however, unfortunately there is rarely any celebration for the constellations that come around. A total of eight constellations come during the month of December, and typically do not receive the recognition they may deserve. Although there may only be a total of eight constellations, there is also a small planetary nebula that appears in various constellations, which supposedly makes up for all of the eight constellations being extremely dull in terms of luminosity.
