Let \(G\) be a connected real semisimple linear group with Lie algebra \({\mathcal G}\). Let \(G=K\exp ({\mathcal A}^+)K\) be a Cartan decomposition of \(G\). Denote by \(m:G\to {\mathcal A}^+\) the map associated with this decomposition and let \(\Gamma\) be a Zariski dense subgroup of \(G\). Let \(l_\Gamma\) be the cone asymptotic to \(m(\Gamma)\). For every \(\eta>0\) and every closed cone \(C\) such that \(C-\{0\}\) is included in the interior of \(l_\Gamma\), every point of \(C\) outside a compact is at distance less than \(\eta\) from \(m(\Gamma)\).
