Since we've only been observing it for 60 years, how do we know it revolves around the sun?

AND THIS HAS NOTHING TO DO WITH IT NOT BEING A FUCKING PLANET ANYMORE

Took the words right out of my mouth.

It does exist, it's just not classified as a planet anymore

Yes, it's a dwarf planet!  :p

It is estimated, but it's predicted that it has an orbit that interferes with Neptune's orbit.  The definition of a planet is that it has to have cleared everything in it's orbit and must be bigger than Mercury.  In a way you might think Neptune's not a planet because of that, but it still is... their definition of a planet isn't really perfect.
Pluto is a dwarf planet.

Isnt this why Pluto is not a planet anymore?

Pretty sure it isn't a planet anymore because it's so small & far off. To WIKIPEDIA!

From Wiki:

From its discovery by Clyde Tombaugh in 1930, Pluto was considered the ninth planet from the Sun. In the late 20th and early 21st century, many similar objects were discovered in the outer solar system, most notably the Trans-Neptunian object Eris which is slightly larger than Pluto. In August 2006 the IAU redefined the term "planet", and classified Pluto, Ceres, and Eris as dwarf planets.[1] Pluto is also classified as the prototype of a family of trans-Neptunian objects.[2][3] After the reclassification, Pluto was added to the list of minor planets and given the number 134340.[4][5]

Did you know it's composed of nitrogen and methane? Yup.

What if it's nothing but an asteroid from that asteroid belt thing (at the edge of our solar system) just floating by?

---

I'm not an expert (Hey, I'm only 15) but at the speed it's going it's trapped in our sun's gravitational pull.  It'd need to be going much faster to just drift by.
If you mean just drift around the sun, well, that's exactly what it's doing.  There's an asteroid in the asteroid belt between Mars and Jupiter classified as a dwarf planet.  Just like Pluto.  That's why they redefined the definition of a planet, so they wouldn't have like 12 planets.
