Of the roughly 10,000 stars visible to the naked eye, only a few hundred have been given proper names in the history of astronomy. [a] Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those, not to individual stars. Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above.
The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated 1022 to 1024 stars.
Largest stars by apparent size The following list include the largest stars by their apparent size (angular diameter) as seen from Earth. The unit of measurement is the milliarcsecond (mas), equivalent to 10×10−3 arcseconds. Stars with angular diameters larger than 13 milliarcseconds are included.

The following is a list of notable galaxies. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe. [1]
The age of the oldest known stars approaches the age of the universe, about 13.8 billion years. Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages about 370,000 years after the Big Bang. [1] This list include stars older than 12 billion years, or about 87% of the age of the universe.
This is a list of stars, neutron stars, white dwarfs and brown dwarfs which are the least voluminous known (the smallest stars by volume).
