There are 217 recognized planets. 220 planets if you want to include our dwarf planets.
In our solar system there are 8 planets, and 3 dwarf planets.
Beyond our solar system there are 209 recognized planets.
The reason we can't detect many planets in other solar systems is because we can only detect the wobble on a star created by high mass planets... The smaller planets don't have a strong pull against their star and cannot be detected from so far away, especially not over the stronger pull of the high mass planets in that system.

In our solar system *. Pluto got the boot as being closer to a comet just too far from the Sun to glow. Oddly we've had little luck finding many planets in other solar systems. Ours seem to be a rarity.
Remember that mas & orbital calculations are all thats needed to detect far away planets. We don't acctually have to SEE them.

Since Pluto is no longer considered a planet, there are 8.
