Solaris Operating Environment is the name of the
UNIX dialect from
Sun Microsystems.
Early versions, based on BSD UNIX, were called SunOS.
The shift to a [System V]? code base in SunOS 5 was marked by changing the name to Solaris 2 (and earlier versions were retroactively named Solaris 1.x).
After version 2.7, Sun began to drop the "2." from the name; the most recent versions (as of late 2001) are Solaris 7 and Solaris 8.
There is also a
movie called
Solaris directed by
Andrei Tarkovsky and based on the novel by
Stanislaw Lem.
There is also an album called
Solaris by
Photek.
