Generally speaking, I'm in the "Pluto is not a (un-adjectived, anyway) planet" camp.

Lists of planets I can live with:
1. Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune.
2. Mercury Venus Earth Mars Ceres Jupiter Saturn Uranus Neptune Pluto Haumea Makemake Eris etc. etc. etc. etc. etc.
3. Sun Moon Mars Mercury Jupiter Venus Saturn
Edited to Add: harvey-ritt reminded me on another list of planets I'm happy with:
4. Jupiter Saturn Uranus Neptune. Plus a bunch of rubble.
Second Edited to Add
5. Mars Venus Mercury Jupiter Saturn Uranus Neptune
Third Edit
6. Jupiter. Nothing else is big enough to actually count.

Lists of planets which are harmful to the very nature of science because they are example of being emotionally tied to a conclusion and denying new data when its discovered, and which are based on denying new understanding of how things work.
1. Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
2. Sun Moon Mars Mercury Jupiter Venus Saturn
Second Edited to Add
3. Mars Venus Mercury Jupiter Saturn Uranus Neptune

Reason I'm okay with "Sun Moon Mars Mercury Jupiter Venus Saturn" being on both lists: it's not SUPPOSED to be a scientific list. It's based on the Babylonian numerological love of the number seven, and Roman gods.

Second edit, at suggestion from yamamnama, is Holst's Op. 32. Definitely fits into both lists.

This list is good: Mars, Venus, Mercury, Jupiter, Saturn, Uranus, Neptune

How is that one defined/compiled?

[yamamanama.livejournal.com]

It's the order of Holst's The Planets.

Added to both lists.

Fair enough. But I still did this image incredibly satisfying:

I find it satisfying as well... until I think about Saturn.

Why is Saturn's ring system depicted, but not those of the other ringed planets (I know Jupiter has a ring, and at least one of Uranus and Neptune but I can't recally off hand which)? (Possible answer: are they too small/dim to see in this scale?)

Why is Saturn's ring system depicted, but not Earth's moon?

If Saturn's ring system is to be considered part of Saturn, shouldn't the whole image be smaller so it matches the other planets? (On second look, the main body of Saturn actually is a little smaller than the others, so perhaps the artist considered this.)

Jupiter Saturn Uranus Neptune

and the rest are Dwarf Planets with hardly any mass at all.

[xiphias.livejournal.com]

Excellent point. I'll edit the original post to include that one, which IS an option I'd support.

Jupiter

If you add up the masses of all the other stuff orbiting the Sun, the total mass is less than the mass of Jupiter. An astronomer observing our system from afar would categorize it as one G2V star with one significant planet and a bunch of detritus.
