This is a list of stars arranged by their apparent magnitude – their brightness as observed from Earth. It includes all stars brighter than magnitude +2.50 in visible light, measured using a V-band filter in the UBV photometric system.
The first list shows a few of the known stars with an estimated luminosity of 1 million L ☉ or greater, including the stars in open cluster, OB association and H II region. The majority of stars thought to be more than 1 million L ☉ are shown, but the list is incomplete. The second list gives some notable stars for the purpose of comparison.
Star Normal maximum brightness is 2.29; magnitude 0.7 once observed 2.39 Epsilon Boötis: Binary star system 2.41 2.14 Mintaka: Triple star system 2.41 Kappa Scorpii: Binary star system Maximum brightness 2.42 2.31 Beta Pegasi: Star 2.42 Eta Ophiuchi: Binary star system 2.440 Phecda: Binary star system 2.45 2.38 Eta Canis Majoris: Star 2.46 ...
Prominent stars in the neighborhood of the Sun (center) This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.
This is the list of notable stars in the constellation Cassiopeia, sorted by decreasing brightness. Name B F Var HD HIP RA Dec vis. mag. abs. mag. Dist. Sp. class Notes
As a star moves toward or away from us, its apparent brightness changes. Sirius is currently the brightest star in Earth's night sky, but it has not always been so. Canopus has persistently been the brightest star over the ages; other stars appear brighter only during relatively temporary periods, during which they are passing the Solar System ...
The Bright Star Catalogue, which is a star catalogue listing all stars of apparent magnitude 6.5 or brighter, or roughly every star visible to the naked eye from Earth, contains 9,096 stars. [1] The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way .
It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
