Show that Petersen Graph minus a vertex is hamiltonian

I need to show that the Petersen graph minus a vertex is hamiltonian, but now all I can think about is that its vertex degrees are in $\{2,3\}$ and that the order is $n=9$ but I do not know how to continue, can you please help me? Thanks in advance.

The Petersen graph is vertex-transitive, since it is isomorphic to the Kneser graph $KG(5,2)$.
