sun-obliquity

The Sun is one of The Five "Discordant" LARGE Non-Planetary Bodies. Its "obliquity" = 7.15 degrees. 

To substantiate this statement, here is a scan of Table 3.1 from The Planetary Scientist's Companion, by Lodders and Fegley,  Oxford University Press, 1998.   You can see "Obliquity to ecliptic" near the bottom left hand corner of the scan.
