Line 1:

'''Acrux''' ([[alpha (letter)|α]] Crucis) is a [[star]] in the [[constellation]] [[Crux]], the Southern Cross. Since the Southern Cross is roughly 60 degrees below the [[celestial equator]], Crux is only visible south of the [[Tropic of Cancer]] and therefore didn't receive an ancient proper name; "Acrux" is simply a combination of the A in Alpha plus Crux. Acrux has a [[stellar magnitude]] of 0.77, and is the twelfth brightest star in the sky. It is the southernmost first magnitude star, just beating out [[Rigil Kentaurus]] (α Centauri).

The page has no educational content except for the current band the guy is drumming for, and includes a ridiculously stupid burn/comment, "He is not a druggie like Johnny and Robby."

Acrux is a [[trinary star]] located 320 light years from the solar system. Only two components are visually distinguishable, α¹ and α², separated by 4 [[arcsecond]]s. α¹ is magnitude 1.33 and α² is magnitude 1.73, both hot [[stellar classification|class B]] (almost [[stellar classification|class O]]) stars, with surface temperatures of about 28,000 and 26,000 Kelvin respectively; their respective luminosities are 2,500 and 1,600 times that of the Sun. α¹ and α² orbit over such a long period that motion is only barely seen. From their minimum separation of 430 [[astronomical unit]]s, the period is at least 1500 years, and may be much longer.

Only page that links to it it [[Goo Goo Dolls]].

α¹ is itself a [[spectroscopic binary]] star, with its components thought to be around 14 and 10 times the mass of the Sun and orbiting in only 76 days at a separation of about one astronomical unit. The masses of α² and the brighter component of α¹ suggest that the stars will someday explode as [[supernova|supernovae]]. The fainter component of α¹ may survive to become a massive [[white dwarf]].

*I would say keep; he's a real member of a famous band. Could certainly be improved; I'll see what I can do. [[User:Meelar|Meelar]] 23:59, 1 May 2004 (UTC)

Another class B subgiant lies 90 arcseconds away from triple Acrux and shares Acrux's motion through space, suggesting it may be gravitationally bound to Acrux. However, if it is indeed located near Acrux, it is under-luminous for its class. It is probably just an optical [[double star]], most likely lying over twice as far away from the solar system as Acrux.
