Pluto is sometimes referred to as a binary system, because the barycentre of Pluto and it's moon Charon, do not lie within either body.
They revolve around a point in space determined by the mass of the planets.

No. Charon and Pluto are different objects that together form a binary system.
There were a total of nine planets in the solar system when Pluto was considered a planet.
There are no double planet systems in our solar system. The closest to being considered a double planet are Pluto and its largest moon Charon, but since Charon is significantly smaller than Pluto, it is not classified as a double planet system.
You mean in OUR solar system. lol. Mercury is now the smallest because Pluto isn't considered a planet anymore.
Because the barycenter of the Pluto-Charon lies between the two bodies, it is a binary system, and one could extrapolate the definition of a dwarf Planet to include Charon. However, the IAU has not yet defined a binary dwarf planet. So the answer is yes and no. If you were to adhere to the current IAU opinion, Charon is a moon. If you would like to adhere to the physics of the system, then yes, they are binary.
Pluto used to be CONSIDERED a planet. Pluto hasn't changed; the definition of a planet has. Charon is a moon of Pluto; since their masses are more similar than Earth and our Moon, they might be considered a binary system.
No. Charon and Pluto are different objects that together form a binary system.
They don't. Charon is generally considered a moon of Pluto, however, since Charon and Pluto orbit a center of mass that is outside of Pluto some have suggested calling the Pluto-Charon system a binary or double planet.
No. They are separate objects. Some have suggested that the Pluto-Charon system be called a binary or double planet, as rather than Charon simply orbiting Pluto, the two orbit around their common center of mass.

It is undecided whether Charon is Pluto's moon or if it is in a binary planet system with Pluto (which is actually a dwarf planet). But using Pluto's orbit, it takes about 248 Earth years (90,613 days) to orbit the Sun completely.
All planets revolve around the Sun. There are no binary planet systems in our Solar System. The dwarf planets Pluto and Charon are possible candidates for a binary system because of the barycentre. The other alternative would be Pluto and Neptune because of Pluto's chaotic orbit.
Charon is the largest moon of Pluto, a dwarf planet that was once considered a planet. Charon is so massive compared to Pluto that rather than Charon orbiting Pluto, the two objects orbit a common center of mass. This leads some to called Pluto-Charon a binary planetary system.
Why did English sentence structure is not in your head? Pluto is in the Solar system. It's just no longer considered a planet.
That could be Pluto with its mate, Charon.(Of course Pluto is only a "dwarf planet" now.)Alternate:Some people have argued that this holds true for Earth and Earth's Moon, although the idea has not caught on. Earth's Moon has by far the largest mass in proportion to its companion planet when compared with any other moon in the solar system.
Nope :)
