why is Pluto so special?

Question

i'm doing a school report on pluto and i need a site that tells me why it's special?

Answer 1

read http:en.wikipedia.org/wiki/Pluto

Answer 2

well, i don't really know a site, but I know why its special.
Some scientists go together and are talking about astronomy and then they relaise: There's no definition for a planet. And the definition of 'a large spheroid circuling a star' includes alot of other masses in the universe, like some astroids and farther away planets. They decided to come up with a more accurate definition, and unfortunately Pluto didn't reach up to these new standards, so it was chucked off the planet list.

Answer 3

The International Astronomical Union decided that Pluto was no longer a planet. Instead, they decided to classify it as a "dwarf planet".

See the details below.

RESOLUTION 5A
The IAU therefore resolves that "planets" and other bodies in our Solar System, except satellites, be defined into three distinct categories in the following way:

(1) A "planet" [footnote 1] is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape [footnote 2] , (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.

(3) All other objects [footnote 3] except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".


Footnote 1: The eight "planets" are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Footnote 2: An IAU process will be established to assign borderline objects into either dwarf planet and other categories.

Footnote 3: These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

RESOLUTION 6A
The IAU further resolves:

Pluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

Answer 4

Well there are several good reasons:

1. He is a dog yet he is able to talk.

2. He is friends with famous people like Mickey AND Minnie Mouse, and Goofy

3. He has been in several famous cartoons

4. He lives at Disneyland.


I hope that helps a little bit. There are more reasons, of course, but this should get you started.


Good luck!
