Working out exactly which stars were or will be the brightest at any given point in the past or future is difficult since it requires precise 3D proper motions of large numbers of stars and precise distances. [1] This information only started to become available with the 1997 Hipparcos satellite data release. [1]
The Sun is the brightest star as viewed from Earth, at −26.78 mag. The second brightest is Sirius at −1.46 mag. For comparison, the brightest non-stellar objects in the Solar System have maximum brightnesses of: the Moon −12.7 mag [1] Venus −4.92 mag; Jupiter −2.94 mag; Mars −2.94 mag; Mercury −2.48 mag; Saturn −0.55 mag [2]
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.
The brightest stars form a shape somewhat similar to that of Ursa Major and Ursa Minor. The total mass contained in the cluster is estimated to be approximately 800 solar masses and is dominated by fainter and redder stars [clarification needed]. [68] An estimate of the frequency of binary stars in the Pleiades is approximately 57%. [69]
Regulus is the brightest object in the constellation Leo and one of the brightest stars in the night sky. It has the Bayer designation designated α Leonis, which is Latinized to Alpha Leonis, and abbreviated Alpha Leo or α Leo. Regulus appears singular, but is actually a quadruple star system composed of four stars that are organized into two ...
The Yale Bright Star Catalogue has been steadily enhanced since the Yale astronomer Frank Schlesinger published the first version in 1930; even though the YBS is limited to the 9110 objects already in the catalog, the data for the objects already listed is corrected and extended, and it is appended with a comments section about the objects. The ...
[9] [10] Despite being designated "ε" , it is the brightest star in the constellation and at magnitude 1.77 is the thirty-third brightest star in the sky. It is the star in the tail of the bear closest to its body, and thus the star in the handle of the Big Dipper (or Plough) closest to the bowl.
The two brightest components of Alpha Librae form a double star moving together through space as common proper motion companions. They are separated in the sky by an angular distance of 231" (3'51"). The position angle of the companion is 314 degrees. The brighter of the two is a white star of spectral type A3, with an apparent magnitude of 2.8 ...
