Pluto is still a member of our solar system. They just downgraded it's classification to dwarf planet. It's still in a solar orbit.
UB313, now officially known as Eris is also classified as a dwarf planet of our solar system.

Pluto is still a member of the solar system, but not as a planet, but one of many of the Kuiper Belt objects. Pluto hadbeen demoted from being a planet in 2006

Pluto is still a member of the solar system, just like the asteroids are. But it is no longer considered a full fledged planet. It is now considered a dwarf planet, which is a new category defined specially to describe things like Pluto and UB313. It is just like how the new category of asteroid was made up in the 1800s to describe things like Ceres and Vesta. Ceres (the first asteroid discovered) was originally called a planet too.

Pluto is no longer defined as a planet, but like all the other dwarf planets, asteroids, and other orbiting objects it is still a member of the solar system.

Debates have raged for a long time on what is considered a planet. Scientists are still arguing over whether Pluto is or should be a planet. However - to keep from having to "accept" asteroids, traveling meteors that decide to stick around, and other space objects as planets, the International Astronomical Union set standards. Pluto doesn't measure up. There has been debate for years as to whether it did, since sometimes it is on our side of Neptune, and sometimes on the other. Since Pluto orbits both the sun and Neptune it isn't really a planet. Why decide? To keep from having to replace the list. Would you really want to have to memorize 276 planets ... or 8?

It is still part of our solar system. Solar, meaning "sun", so anything that revolves around our sun is part of our solar system, even if it is not a planet. Earth's moon is part of our solar system, and so is the asteroid belt between Mars and Jupiter.

Pluto has been traded to Alpha Centauri for two asteroids and a comet to be named later.
