We show that in this case the statistics of local neighborhoods around vertices of $G$ is far from the statistics of local neighborhoods around vertices of any planar graph $G{^{\prime}}$. In fact, a similar result is proved for any minor-closed property of bounded degree graphs.The main motivation of the above result comes from theoretical computer-science. Using our main result we infer that for any minor-closed property $\cal P$, there is a constant time algorithm for detecting if a graph is “far” from satisfying $\cal P$. This, in particular, answers an open problem of {\it O. Goldreich} and {\it D. Ron} [Algorithmica 32, No. 2, 302-343 (2002; Zbl 0990.68103)], who asked if such an algorithm exists when $\cal P$ is the graph property of being planar. The proof combines results from the theory of graph minors with results on convergent sequenc-es of sparse graphs, which rely on martingale arguments. rv:
