Given that the polar coordinate equation of curve $C$ is $ρ=2\cos θ$, and the parametric equation of line $l$ is $ \begin{cases} x=- \frac {2}{3}t+2 \\ y= \frac {2}{3}t-5\end{cases}(t\text{ is the parameter}) $.
(1) Convert the polar coordinate equation of curve $C$ into rectangular coordinates.
(2) Let $M$ be the intersection point of line $l$ and the $y$-axis, and $N$ be a moving point on curve $C$. Find the minimum value of $MN$.
