(work against the mainstream) This is an IMAGINE

Pluto atmosphere was discovered in 1985 – 1988 – http://en.wikipedia.org/wiki/Pluto or at least scientists say this.

Now imagine that is not a atmosphere, I see problemwith the Pluto atmosphere or maybe more problems: physical state of a gas at those temperatures, very big atmosphere for so little gravity, change fast in size and also all this in combination with Pluto rotation axis very inclined.

1 – First we need consider the temperature of Pluto, the temperature of Pluto: Surface temp. in Kelvin:         min:33 K – mean:44 K            max: 55 K – http://en.wikipedia.org/wiki/Pluto – and all this need to by with Sun side and atmosphere is seen by not sun side is seen by contour (from Earth we only can to see atmosphere Pluto by contour).

With this temperature is difficult to understand gases in gaseous form and more according to the combination of this atmosphere:  “Does Pluto Have an Atmosphere?” – “The dominating gas in Pluto’s atmosphere is nitrogen. Carbon monoxide and methane are also present” – http://www.space.com/18564-pluto-atmosphere.html

Notes over melting and boiling point of this Nitrogen: At atmospheric pressure, Melting point of 63.15 k and Boiling point 77.36 K – http://en.wikipedia.org/wiki/Nitrogen – this mean a difference of 14.21 k.

Carbon monoxide with melting point of 68 K and Boiling point  of 82 k – http://en.wikipedia.org/wiki/Carbon_monoxide    – this mean a difference of 14 k

Methane – Melting point of 90.7 k  and Boiling point 109-113 K- http://en.wikipedia.org/wiki/Methane  – this means a difference of 18.3 k to 22.3 k

All this information is at atmospheric pressure, is sure that Pluto pressure is less but not for impossibility the liquid of these gases – “Its surface pressure ranges from 6.5 to 24 μbar” – http://en.wikipedia.org/wiki/Pluto

More: We need to add now that the gases are in ice in the surface planet and need to change to gas for atmosphere (not visible liquid in surface) and by that change directly from solid to gas without intermediate to liquid. The difference between solid and gas is not very high temperature but remember that surface is seen in solid glass and that is the more hot surface (the Sun side) and against this the atmosphere is seen in contour with less temperature that Sun side iced because their surface is at night or near nightfall with low rotation period. (Sidereal rotation period – 6 d 9 h 17 m 36 s – http://en.wikipedia.org/wiki/Pluto)

In our planet there is ice in atmosphere but floating in gas, but in Pluto all the gas is near the ice point by that cannot to be ice in gas because all that atmosphere is iced.

More: Admitting that the glass in Pluto is evaporated in gas form, a time it’s out of floor the temperature need to decrease many and return to glass format. We don’t know the temperature of these gases at the pressure of Pluto but in all form in floor of planet is in solid form and the contour side of the atmosphere need to be less that the Sun side of the planet.

2 – With a so little gravity is difficult to understand so big atmosphere, the gravity is only triple of Moon – http://wiki.answers.com/Q/What_is_the_relative_surface_gravity_for_the_planets  and only 8% of the Earth – http://answers.yahoo.com/question/index?qid=20090406230657AANYEk9

But the atmosphere of Pluto is near 10,390 kilometers – http://www.nbcnews.com/id/49984056/ns/technology_and_science-space/t/plutos-atmosphere-larger-thought-study-shows/#.URGnCvKVEnN against Earth atmosphere of only about 480 km – http://www.enchantedlearning.com/subjects/astronomy/planets/earth/  this is near 22 times less with a gravity of 12 bigger. This is equivalent to a atmosphere in Earth of 22×12 = 264 in high over actual (an atmosphere in Earth of 264 times in high would to be many times more in 3d).

(“From the rate of dimming, the atmospheric pressure was determined to be 0.15 pascal, roughly 1/700,000 that of Earth.” – http://en.wikipedia.org/wiki/Pluto – (or double – 0.30 pascal in same page) with this so little pressure cannot to be an atmosphere, only are gas, liquid or ice of gas (solid) in orbit)

3 – An atmosphere normally change few, but Pluto atmosphere has big changes: “Pluto’s atmosphere changes really fast!” – http://planetary.org/blogs/emily-lakdawalla/2011/3008.html  – and also “Pluto’s atmosphere recently expanded dramatically” – http://news.sciencemag.org/sciencenow/2011/04/plutos-expanding-atmosphere-conf.html

This is false (in all this years Pluto has not change from position and has been very big changes in atmosphere)   “When Pluto swings near the sun, the sun’s heat evaporates the ice and gases slowly escape into space. This process continues until Pluto moves away and the sun’s heat fades. Then, the ice builds up until Pluto approaches the sun again.” – http://www.nbcnews.com/id/49984056/ns/technology_and_science-space/t/plutos-atmosphere-larger-thought-study-shows/#.UQ116_JfHUg

Pluto has an orbital period of 246.04 years – http://en.wikipedia.org/wiki/Pluto this means that from discover in 1985 has made 28 years/246 = 11% of 1 orbit, by that impossible have seen neither half orbit). Or better : “Pluto’s last close approach to the sun was in 1989. That is considered a fairly recent event, because it takes 248 years for the dwarf planet to orbit the sun once” – http://www.nbcnews.com/id/49984056/ns/technology_and_science-space/t/plutos-atmosphere-larger-thought-study-shows/#.UQ116_JfHUg this means that is so very close to the distance in that moment.

More: really is against hot temperature, the closed distance was in 1989 but the atmosphere in present days is bigger that in the past known.

“Pluto’s atmosphere larger than thought, study shows” – http://www.nbcnews.com/id/49984056/ns/technology_and_science-space/t/plutos-atmosphere-larger-thought-study-shows/#.UQ116_JfHUg

4 – atmosphere definition : “The gaseous mass or envelope surrounding a celestial body, especially the one surrounding the earth, and retained by the celestial body’s gravitational field” – http://www.thefreedictionary.com/atmosphere

We can consider that is difficult to be according to atmosphere definition for Pluto (gaseous mass).

5 – We can add also that “Pluto rotation axis is of 122°.5 to its orbital plane” and “it presents its poles and its equator alternately towards the Sun and the Earth as it moves around its orbit” – http://oxfordindex.oup.com/view/10.1093/oi/authority.20110810105625485 or by an image in http://www.onr.navy.mil/focus/spacesciences/solarsystem/intro2.htm in fact that can be near to Saturn rings.

We also need consider that Saturn is not the only with rings, they are also discover in Jupiter – http://en.wikipedia.org/wiki/Rings_of_Jupiter.

Imagine Saturn rings with that inclination and not only at near 26º (http://answers.yahoo.com/question/index?qid=20081111180619AADqkAv) like you can compare in http://www.onr.navy.mil/focus/spacesciences/solarsystem/intro2.htm in that conditions probably the rings of Saturn we confuse with an atmosphere.

xxxxxxxxxxxxxxxxxxxxxxx

Really seem near orbit or rings and near impossible in atmosphere of gas (atmosphere only can to be in gas format).

In relation to orbit we can affirm that Pluto has moons in orbit at more distance and by that in good relation, also in Earth we can see that Moon is far but in shorter distance there are many other satellites and by that is totally correct take in relation with orbit.

Also is important the very quick changes of that supposed atmosphere (from now I call it like orbit or ring) and this is very probably by solar wind that in actual moment is growing with big activity.

Also we need use the same information for other seen atmospheres in zones so cold in other solar systems and consider are orbit and not atmospheres.
