The mass of the newly discovered pentaquark is calculated within the
framework of the SU(3) Skyrme Model. Various estimates based on the \emph{model
independent} approach are compared with the model results and with the Chiral
Quark Model. Our discussion shows that $\Theta^{+}$ is light with the mass of
the order 1.5 GeV.
