According to Jairo comment on the first version of this question I revise the question as follows; Let $g$ be a real analytic Riemannan metric on $S^{2}$. Is it true to say that: There are at most a finite number of disjoint simple closed geodesics on $S^{2}$. If the answer is yes put $m$= the sup of the number of such disjoint closed geodesics. What is a geometric interpretation for this geometric invariant $m$? For a given $n\in \mathbb{N}$, is there a real analytic Riemannian metric on $S^{2} $ for which $m=n$
