Such multiple star systems are indicated by parentheses showing the individual magnitudes of component stars bright enough to make a detectable contribution. For example, the binary star system Alpha Centauri has the total or combined magnitude of −0.27, while its two component stars have magnitudes of +0.01 and +1.33. [3]

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.
Some of the faintest stars visible to the unaided eye have magnitudes of about 6.5. ... “The moon is bright tonight, making it difficult to find the comet with the naked eye. On Feb 10th, the ...
According to the Farmers' Almanac, there have been several celestial events that have been referred to as the Christmas Star. In 2020, Jupiter and Saturn were so close together they looked like ...
Vega is the bright star near the bottom. Each night the positions of the stars appear to change as the Earth rotates. However, when a star is located along the Earth's axis of rotation, it will remain in the same position and thus is called a pole star .
Astronomers advise people hoping to see the planetary phenomena to go to an area with minimal light pollution and to allow at least 30 minutes to allow vision to adjust to the darkness.
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.
