I must've missed the memo that Pluto was no longer a planet. When did that happen? Wonder what they're now teaching in the grade schools, is the solar system only 8 planets now?
Yes. The solar system is now only 8 planets. Pluto was downgraded to "dwarf planet" status in 2006. The reason for that is because Pluto did not fit the definition of a planet.
A planet is a celestial body that is in orbit around the Sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and has cleared the neighbourhood around its orbit.
The term "plutoid" came from this decision.
This group decided that Pluto was not really a planet because of its size and location in space. So Pluto and objects like it are now called dwarf planets. Pluto is also called a plutoid. A plutoid is a dwarf planet that is farther out in space than the planet Neptune.

So are those dark spots oceans of hydrocarbons or just dark material?

It disappoints me how little attention this has been getting. Sure I've seen it mentioned here and there but people should be more excited about this than they are.

So what was Pluto from 1979-1999, when it was closer to the sun than Neptune?

Classified as planet at the time. In reality it was just a dwarf planet. Plutoid is a new term.

I remember the good old days when Pluto was still considered a planet and all the talk was about Planet X.
There's a special on New Horizon and Pluto Tuesday evening on NatGeo.

Isn't it just a big ball of rock and ice? It's cool that we're getting these pictures and all, but are there any other benefits of the fly by? Don't we already know most of what needs to be known about Pluto?
you should watch tomorrowland and listen to the kids reason for building a rocket pack
then you'll have your answer

"Let's see if I can remember the planets: Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus, Neptune, Pluto."
There is a memory devise for this. Can't recall at the moment. Anyone help?

The way I remember being taught it was the smallest planets are closest (excluding Pluto at the time, obviously) then there's an asteroid belt, then the gas giants.
