Did you want me to re-count the same points as errors in the summary section?

ERRORS IN "SUMMARY"

12. "If Pluto is a planet, it should be the largest planet, because it is the farthest from the sun"

13. "it is bigger than Mercury"

14. "If Pluto is a planet, it should rotate in the same direction of the rotation of the sun around its axis"

15. "but Pluto revolves in the opposite direction"

16. [in refrence to Pluto's orbit making it closer to the sun than Neptune at certain times] "this confirms that it revolves around Neptune "

The corrections should be as follows:

1. Pluto is not a moon of Neptune. It orbits the sun, along with the barycenter between itself and Charon, although the Charon bit was not known at the time of the claims.

2. No astronomers I have known have ever stated this. It revolves counterclockwise (as seen from "above" the solar north pole), just like all 8 planets.

3. It's size is based on the avaliable matter at the regions where it formed were, and gravitational influences. Since there are four gas giants out in that direction, most of the matter in the outer solar system was used to form them. Pluto (and the other far distant bodies) are small because of what remained, and what was avaliable. There is no mathematical formula (that I have seen) that states a body orbitng a star *must* be large if it is farther away from it's star. In fact, many of the first exoplanets discovered are larger than Jupiter, and closer to their star than 1 A.U.

4. The IAU made no such condition on the definiton of the term planet, so far as I can understand. Not that it would matter anyway, since Pluto DOES orbit in the same direction as the 8 planets.

5. This appears to be a repeat of error number 2.

6. There isn't really a threshold on the radius of an object for it to be considered a moon of a planet, mathematically, mass and distance could play a role as to whether an object orbiting a planet would have a "center of gravity" within the planet or not.

7. I have no idea how this claim has any validity.

8. Pluto radius = 1180km

Mercury radius = 2439km.

Doesn't look bigger to me.

9. Pluto radius =1180km

Earth radius = 6378km.

Only if "half" is equal to about .185

10. Entire statement should be removed.

11. <---this is true for roughly half of the globe, "east to west" would have been a better phrasing than "left to right" ...although we actually do see it revolve around the earth west to east, they did correctly state that our rotation period is faster than the moons orbital period, and so the rise/set phenomenon is more apparent in its visual motion than its orbit.

12. By this logic, Mars can't be a planet, because it is smaller than earth, but more distant than the sun. The same reasoning would make Saturn, Uranus, and Neptune not planets as well, but "moons of Jupiter"

13. See correction to #8

14. First of all, it does! But that has never been a prerequisite for something to be considered a planet anyway.

15. False.

16. Wrong. For starters, it has a much different inclination to it's orbit than Neptune. But it certainly does not orbit Neptune. In fact, there is no guarantee that Neptune and Pluto will even be on the same side of the sun during the approximate 20 years out of the Plutonian year that it is closer to the sun than Neptune. If it were a moon of Neptune, wouldn't they have to have the same orbital period around the sun?

<EDIT>

I added the errors from the "summary" section of that website.

A suggestion for the "limited space" in your explanation fo best answer is, you could also put details in the "comments" section of the question, after the question has become "resolved."

Well, let's start off with some of the basic facts that were Falsely written on that Page. First of all, Pluto is not a Planet, nor a moon. Pluto is a Dwarf Planet, and it does Not revolve around Neptune, instead it revolves around the Sun, as do the other planets, and the moons revolve around them.

This page wrote false facts about how Pluto should be the Largest planet in our Solar System because it is the furthest in the Solar System. This is False! Our Planet's positions are not based on their Size, because over time we've come to realize that in other Solar Systems, Out there, around other stars, there are sometimes Giant Planets closer to the sun, and smaller planets furthur away, and sometimes the Giant Planets are furthest, and the smaller planets are very close by. Again, It's position is not based by it's size!

Of course, if it's smaller, the Sun will have an easier effect on it, and if it's bigger, the sun will have a heavier effect on it (gravitational attraction).

Again, Pluto does Not revolve around Neptune, and this was mentioned way too many times. This page claims that as Pluto and Neptune orbit around our 'Sun', Pluto gets often closer to Neptune, and other times Furthur away, and According to this page, that means that Pluto is Actually Neptunes Moon! FALSE! Pluto is actually orbitting our Sun, and just because it has an unstable orbit, that does Not mean it is orbitting another Planet, even if it may have some (or any) gravitational effect.

And finally, even though the Sun is rotating in one Direction, Pluto does not have to Orbit it in the Same Direction.

Think of Asteroids and Comets, when they enter our Solar System (if not in it Already), they can travel through it, and orbit the sun (or slingshot around it) from either side, without being affected Too Much by it's Rotation. It would make sense for an object to orbit our Sun in the same Direction the Sun was going, but it All depends on when and how this Object entered our Solar System, and I'm not sure we know too much about Pluto's History, instead, we can Theorize.

And Theories are the key to Solution.

I really hope this helped!

1. If Pluto is a planet, it should be the largest planet, because it is the farthest from the sun. (but it is relatively small: it is bigger than Mercury and smaller than Venus.)

This is a false statement, but otherwise ambiguous for the main reason that Pluto once belonged to a much larger satellite. It is interesting to note that Pluto came, more than likely from the Oort Belt.

It is a planet, now-though perceived differently-as it is no longer considered a cumbersome entity. partially true.

This is going to be fun:

1) "I say that if Pluto was one of the planets, then it should be the biggest of the planets in size; because it is the farthest in distance from the sun than the rest of the planets"

Wrong, otherwise Saturn, Uranus, and Neptune would all be bigger than Jupiter.

2)"and it must revolve around the sun exactly like the revolution of the rest of the planets from right to left, then how could it happen that the revolution of Pluto is in the opposite direction"

Just plain incorrect. Pluto revolves around the Sun in the same direction as all the other planets.

3)"Moreover, if the size of Pluto is equal to half that of the Earth, then it is one of the satellites which belong to the planets."

Pluto is much smaller than half the size of Earth.

4) "If it was one of the planets, then its position would be between Mercury and Venus; because it is bigger than the first and smaller than the second"

Pluto is the smallest planet, and yes that means it is smaller than both Mercury and Venus.

5) "As regards to its revolution, [Pluto] revolves around Neptune just like how does our Moon revolve around Earth."

Just factually untrue.

*EDIT*

Now for true statements:

1) "He said: " Astronomers, however, think that Pluto is a planet"

Presuming that this quote is from the author's book in 1947, then the author is correct that astronomers classified Pluto as a planet at this time.

One can only hope that people will start using their own common sense to select political candidates based on what they have the potential to do to better the lives of all Americans rather than on their religious beliefs. I believe that the religious right, in their attempt to catapult Huckabee to the forefront of he Republican party, has effectively handed the presidency to a democrat, which should prove to all thinking Americans that this religious "body" is not only biased, but also inept!

Hi. "2. If Pluto is a planet, it should rotate in the same direction of the rotation of the sun around its axis, which is the same direction of revolution of the rest of the planets around the sun: from right to left. (but Pluto revolves in the opposite direction.)" This is false.

I hardly know where to begin, also. It would be fair to say that the errors begin at the heading and end with the final period.

Get back to you.

Wow, That is a lot of work for a lousy 10 points.

whoa i found like 10 things i didnt know in there

i do know though that pluto is not neptunes moon

Ohhh, I thought you said 'facial mistake" my bad...and just for the record...you look great to me Suitti, as always. *hugs*
