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]
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 first star in the list, Godzilla [1] — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the 19th ...
The primary is a blue-hued star of magnitude 3.5, 82 light-years from Earth, and the secondary is an F-type star of magnitude 6.6. [2] Tau Ceti is noted for being a near Sun-like star at a distance of 11.9 light-years. It is a yellow-hued main-sequence star of magnitude 3.5. AA Ceti is a triple star system; the brightest member has a magnitude ...
R136a1 is separated from R136a2, the second brightest star in the cluster, by 5,000 AU. [ 15 ] R136 is located approximately 157,000 light-years from Earth in the Large Magellanic Cloud, positioned on the south-east corner of the galaxy at the centre of the Tarantula Nebula , also known as 30 Doradus.

SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, [3] and exceeding roughly sixteen times the brightness of Venus.
