If Pluto is considered a Dwarf Planet, then how come it still orbits the sun due to the gravitational pull?

I think you may be confusing dwarf planets with dwarf stars like red dwarves, yellow dwarves, black dwarves, and white dwarves. These are completely different things. As GreenWinter says, we can't even detect most of the expected dwarf planets in our own solar system. We can barely detect planets much larger than Earth in others, let alone dwarf planets.

Everything in the solar system orbits the sun and yes, other solar systems have dwarf planets

Pluto was cut out of the Major Planet Club (MPC) because it wasn't paying its dues. But it still hangs around the neighborhood with a bunch of kids, trying to get back in.

Carol wrote that she expects the s**t to hit the fan at the 2016 IAU conference, after the flyby of Pluto shows that Pluto has cleared the neighborhood. But it is already a given that Horizons will never discover any objects perturbing Pluto. The small number of large Kuiper Belt Objects are spread very far apart. They are normally in a region from 30-50 au. They stay very far away from each other. Carol misunderstands the nature of orbit-clearing. The key here was expressed by a finding by Steve Soter.. All the planets have at least 24,000 times as much mass as the rest of the orbital zone. With Pluto, the number is .08 and it is less than a tenth of the zone.

Yes due to gravity, like all orbits.

the main reason was they were worried that they would find hundreds of dwarf planets and it would be unreasonable for everyone to have to learn all their names. There are some I consider to be "worlds" so to me they're a class of planet, but I don't have a job that makes my opinion valid. Anyway, currently there are about 10 dwarf planets I consider worthy of calling them planets/worlds, so to me their concern has so far not held up, but they do have a point. I don't think it would be reasonable of me to expect 8 year-olds to learn all their names, and so far what is known about them is kind of limited. Interesting? yes. limited? learning more, and once Horizon gets further out things could get much more interesting. to me Ceres, Humea, Makemake, Sedna, Eris, Quaoar, Pluto and Orcus are worlds. There are over 50 dwarf planets and I haven't looked deeply into all of them yet. And that number actually could rise as more are discovered. But they are all tiny, so it's not sinister that Pluto is no longer considered a planet and is instead a dwarf planet. You're forgetting our solar system extends about half way to the nearest star. It's gravity is that strong.

If Pluto is considered a Dwarf Planet, then how come it still orbits the sun due to the gravitational pull?: who made the rule that a DP (Dwarf Planet) shouldn't orbit the Sun? Is it IAU or UAI? I'm just asking because other dwarf planets are yet to become a star close to our solar system, yet Pluto still stays in range of orbiting the sun isn't that strange? : I know you are asking because every DP is a star at the end of the show. I see many of them in the movies. [today I learnt one thing - a DP becomes a 'star'.] And if it's just a coincidence then how come other dwarf planets don't orbit other solar systems?: But IAU permitted them to orbit the Sun, only you, Plutophiles blocked it. They don't need to go to the other stars. Ask yourself, due to the economy did people cut the ninth planet out just for money; business? : You are way ancient. There is already a tenth planet, PlanetX. I didn't measure it to see whether it is also a dwarf. It is the business of Americans (& American businesses) to accord which one to become a DP. None else has that right. They can pluck a Pluto from its orbit & put it in a doghouse.

No, it is NOT strange at all, Pluto was NOT reclassified as dwarf planet by 4% of the IAU membership (after all the planetary scientists had left the conference) by voice vote at the end of scientific conference because of the economy or business reasons. Pluto was reclassified for good SCIENTIFIC reasons , I expect the "sh** to hit the fan" at the IAU national and international conference in 2016 AFTER the New Horizons probe makes it's flyby's of Pluto and it turns out that Pluto HAS cleared "its neighborhood of similarly sized objects." The IAU painted itself into scientific hypocritical corner in 2006. How Humanity classifies Pluto does NOT matter to Pluto. Pluto has been orbiting in 2:3 gravitational resonance with Neptune for VERY VERY LONG TIME. THAT is NOT going to change no matter how many tempests in teapots the IAU members create. "...Mike Brown (born 5 June 1965) has been a professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003.[1] His team has discovered many trans-Neptunian objects (TNOs), notably the dwarf planet Eris, the only known TNO more massive than Pluto.[2] He has referred to himself as the man who "killed Pluto",[3][4] because he furthered Pluto being downgraded to a dwarf planet in the aftermath of the discovery of Eris and several other probable trans-Neptunian dwarf planets. He is the author of How I Killed Pluto and Why It Had It Coming, published in 2010...." http://en.wikipedia.org/wiki/Michael_E._Brown
