According to Jairo comment on the first version of this question I revise the question as follwos;
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  $m=n$
