Can we have infinitely many conjugacy classes of stabilizer subgroups?

Question

Let $G$ be a compact connected Lie group acting smoothly on a smooth connected manifold $M$. Say that $p,q\in M$ have the same orbit type if their stabilizer subgroups $G_p$ and $G_q$ are conjugate in $G$.

Can there be infinitely many orbit types?

In other words, if $[G_p]$ denotes the conjugacy class of $G_p$ in $G$, is it possible that the set $$\{[G_p]:p\in M\}$$ is infinite?

Answer 1

There exits finitely orbit type if $M$ is compact. See p. 15 here
