Querying Version Information
Solaris, based on BSD Unix, was initially called SunOS.
SUN Microsystems started to develop System V Release 4 (SVR4) from SunOS 5.0 and gave it a new name Solaris 2.0. After Solaris 2.6 was released, SUN Microsystems renamed SunOS 2.10 to Solaris 10. Later, the earlier versions of Solaris were renamed to Solaris 1.x.
Therefore, the word "SunOS" is used to exclusively indicate the Solaris operating system kernel. Based on this, it is deemed that Solaris consists of SunOS, GUI, and other network enhancements.
Querying the Current Solaris Version
To query the current Solaris version, run the following command:
bash-3.2# cat /etc/release
Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC

In the command output, Solaris 10 8/11 s10s_u10 indicates that the OS is Solaris 10 U10 released in August, 2011; Solaris 11.3 SPARC indicates that the OS is Solaris 11.3 released in October, 2015.
