How many nodal plane(s) is / are present in ${\stackrel{*}{\mathrm{\pi }}}_{2_{p_y}}$ antiboding molecular orbital?

${\mathrm{\pi }}^{*}2{\mathrm{p}}_{\mathrm{y}}$ has two nodal planes, it is an anti-bonding orbital which is formed by destructive overlapping of two p-orbitals. One node is already present in p-orbital and another node formed due to destructive overlapping of two p orbitals.
