The Brightest Stars
Below you find a list of the brightest stars in the sky (up to 2.5 mag). The asterisk at the spectral type of some stars indicates that it is a binary; the spectral type of the brighter component has been listet.
The table lists the 152 visually brightest stars of the sky, those through visual magnitude 2.
The following list contains the 100 brightest stars as seen from the earth at night. The information on magnitudes is taken from data obtained by the Hipparcos Satellite Catalog.

List of brightest stars
Bright stars are bright because they have high luminosities and/or they are nearby. Below are the 90 brightest individual stars as seen from Earth in visible wavelengths (apparent magnitude less than or equal to +2.50).

The brightest stars of Norma are of only fourth magnitude and none have names. Because of changes in the constellation's boundaries since Lacaille's time, Norma no longer has stars labelled Alpha or Beta.
The brightest stars in the picture (easily distinguished by the spikes radiating from their images, produced by optical effects within the telescope), are foreground stars lying within our own Milky Way galaxy.

The two brightest stars in Gemini, [3940] alpha and [3938] beta Geminorum, are better known as Castor and Pollux, and represent the twins' heads. Both are among the brightest stars in the night sky.
The nine brightest stars of the Pleiades are named for the Seven Sisters of Greek mythology: Sterope, Merope, Electra, Maia, Taygete, Celaeno and Alcyone, along with their parents Atlas and Pleione.
One of the brightest stars to change its position significantly at rising was Arcturus (Alpha Boötes). In the 2000 years following the Pyramid Age, it shifted southward along the horizon about 0.7° in azimuth per century.

When we list the brightest stars in the sky, we find that most of them are much larger than the Sun, emitting many times as much power as the Sun. The brightest star in the sky, Sirius (&alpha Canis Majoris), is only 2.
Like many of the brightest stars in Earth's sky, Antares figures prominently in science fiction.

(pronounced "beetle juice") Betelgeuse (alpha Orionis) is the second-brightest star in the constellation Orion and one of the brightest stars in the sky.
The stars cataloged by Ptolemy (2d cent. A.D.), all visible with the unaided eye, were ranked on a brightness scale such that the brightest stars were of 1st magnitude and the dimmest stars were of 6th magnitude.
Well before a galaxy is truly resolved into even its brightest stars, the image will be mottled by statistical fluctuations; for example, if the surface brightness is such that there are 100 red giants per seeing disk, ...
The system was invented by Johannes Bayer around the year 1600; it used the familiar Greek alphabet for the 24 brightest stars in a given constellation, and the Roman alphabet for fainter stars.
Among the representatives of Population I, the brightest stars provide a unique opportunity to study the evolution of massive stars and the upper limit to the mass that a star can have and remain stable.
He called the brightest stars first magnitude stars, the ones he felt to be half as bright second magnitude, and so forth down to the faintest visible stars which were sixth magnitude. Notice that this means that magnitudes go backward, i.e.
In his magnitude system, the brightest stars were called first magnitude stars, and the dimmest were sixth magnitude stars. So, in this system, brighter objects have lower magnitudes than dimmer objects.
This photograph above shows a large part of the southern sky, from Crux to Orion, and includes the two brightest stars in the sky, Sirius and Canopus.
The brightest stars, supernovas, star clusters, and gas clouds have been used for this purpose.
This cluster has also been named the Seven Sisters, after its seven brightest stars. These stars can easily be seen with the naked eye. The Pleiades are believed to be very young - only 100 million years old.
It's the ninth largest constellation and it contains two of the ten brightest stars. No other constellation can make this claim although Orion the Hunter and Crux the Southern Cross each contain two of the twenty brightest stars.
I - in which the brightest stars are hot and white; and II - in which the brightest stars are old Red Giants. This is an odd distinction because the first stars to have populated a given region would now be classified as Population II! ...
Magnitude: Astronomical brightness measured on a logarithmic scale, based on the ancient practice of noting that the brightest stars in the sky were of "first importance" or "first magnitude", the next brightest being "second magnitude" etc.
The stars selected to be examined for parallax are usually either the brightest stars or those with an especially large proper motion. Neither criterion is a guarantee that the star shall have a measurable parallax.
3, which would make it one of the 20 brightest stars, if it were a star. Rusty red in color, Mars can be found just 5 1/2 degrees above the western horizon, just barely to the north.
In ancient times, stars were ranked in six magnitude classes, the first magnitude class containing the brightest stars. In 1850 the English astronomer Norman Robert Pogson proposed the system presently in use.
Its brightest stars mark the Northern Cross. Cygnus, with the bright star Deneb in the swan's tail, appears high in the summer sky.

Many of the brightest stars visible to the unaided eye have been named in "ancient" times. The customs and traditions for naming stars have changed over time.
Venus is always brighter than the brightest stars, with its apparent magnitude ranging from âˆ'3.8 to âˆ'4.6. This is bright enough to be seen even in the middle of the day, and the planet can be easy to see when the Sun is low on the horizon.
Variable high level ice fog caused light scatter which highlighted color of the brightest stars in this beautiful cluster. Cookbook 245 LDC camera was used on Celestron Ultima 8 SCT with f3.0 focal reducer.
Rigel (beta Orionis) is the brightest star in the constellation called Orion and one of the brightest stars in the sky. It is a blue (very hot) supergiant, over 60 million miles in diameter (almost 100 times bigger than the sun).
DoDz10 - larger, loose and scattered. The two brightest stars in the cluster are close doubles.
DoDz11 - small, faint, stars are arranged in a linear fashion. The two brightest stars in the cluster are close doubles.
Eta Carinae was the site of a giant outburst about 150 years ago, when it became one of the brightest stars in the southern sky. Though the star released as much visible light as a supernova explosion, it survived the outburst.
"What this paper is showing is that some of the standard assumptions that we've had - that the brightest stars tell you about the whole population of stars - this doesn't seem to work, at least not in a constant way, ...
Incidentally, the constellation Gemini's brightest stars, Pollux and Castor, shine to the Moon's immediate right tonight, nearly in line with the Moon; and the intensely bright point of light to the Moon's upper left is the planet Jupiter.

"As an astronomer, some of the brightest stars I discover are in the classroom," Odenwald said.

magnitude: the brightness of a star, ranging from 1st for the brightest stars to 6th for the faintest that can be seen with the un-aided eye. Originally defined by Ptolemy, it is sometimes indicated on astrolabes.
The brightest stars are first class and those slightly fainter are second class. The sixth class is the faintest stars that he cold see with the unaided eye. The magnitude scale is logarithmic like the eye.
