As far as we can actually PROVE, it is the only dwarf planet that orbits our own Sun. However, there has long been some speculation that there may be another dwarf planet out beyond Pluto, that is even smaller, but which is too far away from the Sun to be seen with optical instruments. It has also been debated that some large meteorites that orbit the Sun between the orbits of the planets, should maybe be declared as being dwarf planets in their own right.
Back when Pluto was a planet and not a dwarf planet, it sometimes Neptune to be the ninth planet because their orbit crossed. Now that Pluto is a dwarf planet, there are only eight planets in the solar system.
Pluto may not only be a dwarf planet but possibly a moon
Pluto is considered to be two different things. 1. Pluto is a dwarf planet. It is in hydrostatic equilibrium (round) and it orbits the sun, but it has not cleared its neighborhood of debris. What's its neighborhood? The Kuiper belt, a collection of icy objects similar to comets that somewhat resembles the asteroid belt. This leads to its second classification. 2. Pluto is a Kuiper Belt Object (KBO). Specifically, it's classified as a plutino - an object within a certain zone of the Kuiper Belt.
It depends if you count all planets, or just dwarf planets:On the list of all 13 planets including dwarf planets, pluto is the 10th from the sun.If you only count only the 5 dwarf planets, it is the second dwarf planet from the sun (the first is Ceres).
Pluto was recently reclassified as a dwarf planet after being considered the 9th planet for over 80 years. This was due to the discovery of several Pluto-sized objects is similar orbits to Pluto, and the suspected existence of hundreds or thousands more.

Generally, a dwarf planet orbits only the sun, whereas a moon orbits a planet, which in turn orbits a sun.
Makemake is the second dwarf planet from Pluto (moving away from the sun). The only dwarf planet in between the two of them is Haumea.
No, it was only reclassified as a dwarf planet
Pluto may not only be a dwarf planet but possibly a moon
No.It is a satellite (moon) of Pluto, which itself was declared a "Dwarf Planet" at the International Astronomical Union (IAU) Symposium in 2006.Pluto is very small - only 2/3rds the size of Earth's moon. Charon is 1/2 that size - which is large enough that the IAU would have faced calling Pluto-Charon a "Double Planet" if they had decided to call Pluto one.However, IAU's decision was based upon the fact that there are MANY objects in similar orbits to Pluto's (some even larger than Pluto itself, such as Eris), and we would have ended up listing dozens (possibly hundreds) of objects as "Planets"No. Charon is not a planet; it is a moon of the dwarf planet Pluto.

No. It was the first planet to be downgraded to the title of a dwarf planet.Before Pluto became a dwarf planet, we discovered several other small, Pluto-like planets such as Ceres (Discovered on January 1st,1801), Eris(Discovered on January 5th,2005) , etc.
Pluto is no longer a planet it is now a dwarf planet. There are only 8 planets in our Solar System.
No, the only dwarf planet closer to the Sun than Pluto is Ceres.
