re: The upcoming flyby of Pluto will be the first for a planet in 25 years

I don't think so...the pictures of Uranus were taken with a Brownie

That is the criteria that they say disqualified Pluto from being the 9th planet.
I understand that. But we consider Earth to be a planet because we live here - so it isn't exactly a relevant comparison. Everything else is just a ball of mass.

sorry... for the planetary ignorant - what does clear its orbit mean?

In basic terms, clearing its orbit means that the planet is the dominant gravitational force in the area, there's nothing left in the area to compete with the Earth for gravitational dominance. The only significant body in the area of the Earth is the moon, which is dominated by the Earth, forcing it into its orbit as a satellite.
On the edge of our solar system is the Kuiper belt, and Pluto is located within it. It competes for gravitational dominance with the other objects within the Kuiper belt, which downgrades it to "dwarf planet" status. It isn't even the largest known thing in the Kuiper belt.
There are enough of these dwarf planets in the Kuiper belt to justify setting them aside as a classification distinguished from normal planets.
There is no reason for Pluto to be considered a planet when you factor that in, unless you just wanted to grandfather it in for old time's sake.

One question is what makes something a 'dwarf' planet? Is that relative to Mercury? The Earth? Jupiter? All of the inner planets are dwarves compared to the gas / ice worlds.

Who are we to say it can't be a planet? Maybe it feels like it was born a planet and that is its true identity.

Whether or not something is considered a dwarf planet or a regular planet has nothing to do with its size in absolute terms.
An object is a planet if it has enough gravitational force to become nearly perfectly spherical and it orbits a star. If it has cleared its orbit, it is a regular planet; if it has not cleared its orbit, then it is a dwarf planet.
Yes, if you took a planet and placed it in a different part of the solar system, of course its behavior would change and thus it would cease to be a planet and would be considered something else.
If you put Pluto in motion next to Jupiter, Pluto would orbit around Jupiter (after all, Jupiter's moon Ganymede has a larger mass than Pluto). Using your logic, does that mean we should call Pluto a moon now?

Just think about the time involved in this.
Cell Phones used by scientists when funding was approved by NASA in 2001.
Cell phones used by scientists when the probe was launched in 2005.
This thing is older than most people's cars and has been cruising around in space. Think about putting all kinds of time and effort into this project and having to wait a decade to see if it works.
I'm excited to see what new discoveries come in the next years from this.

Are these images going to eradicate racial oppression and suppress white privilege - the true issues of our time?
If not, this has all been a colossal waste of time and money.

That's "little person" planet. You're so un-PC

BTW, two days from now the probe should be able to achieve better resolution images than the Hubble. Expected flyby is to take place July 14th.
Initial compressed images should be available within a day or so, but full quality images will take and estimated 9 months to transmit.
Eat your heart out, AOL.
