is it true pluto is nolonger considered a planet if so why?

Answer 1

Because there was no one to speak up for the Plutonians at the conference table....we always pick on the little guys.

Answer 2

Astronomers consider Pluto to no longer be a significant planet. It is now considered to be a minor body, like Ceres in the orbit between Mars and Jupiter, and some bodies in the Kuiper Belt (i.e., beyond Pluto's orbit).

Pluto is in a highly elliptical orbit, outside of the normal ecliptic plane that the Planets are in. It's moon, Charon, is almost as big as Pluto. This causes the centerpoint for their orbit to be outside of Pluto. No other moon is so similar in size to its planet.

Those and other reasons mean Pluto really shouldn't be considered a planet.

Answer 3

It is true, it is no longer considered a planet. I believe it was because it does not clear it's own orbit of debris. It's now being called a Dwarf Planet:

- Planets: The eight worlds from Mercury to Neptune.

- Dwarf Planets: Pluto and any other round object that "has not cleared the neighborhood around its orbit, and is not a satellite."

- Small Solar System Bodies: All other objects orbiting the Sun.

Answer 4

You are, indeed, correct in that assumption! It's because astronomers have decided that it fits into the same category as a moon or asteroid- no rotation, no chance of life, and because it's, like someone else has already said, just a rock! So forget about all the past history you've learned- Pluto is too goofy to be a planet!

Answer 5

Officially, Pluto is no longer a planet as of 2006.

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


Scientists redefined what a planet is, and Pluto doesn't meet those "requirements" so it is considered a dwarf-planet---not an actual "planet"...

Answer 6

Yes, its considered a dwarf planet now. Pluto is basically a mass of rock and ice that got sucked into the sun's gravitational pull from the Oort Cloud.

Answer 7

It's true. Pluto is smaller than two other spacial objects, which sparked a debate over whether it should remain a planet or not. It was decided that a new category should be created: plutons, in which Pluto is now included.

Answer 8

Yes. Pluto barely meets the requirements to be a planet and leans more to being a huge asteroid. Too small to be a planet, too big to be a comet.

Answer 9

It is true, Pluto is no longer a planet. It is too small, and its shape is consider not round enought for a planet, it is a big rock

Answer 10

"That which we call a rose by any other name would smell as sweet."
- Shakespeare's Romeo and Juliet, 1594

JULIET:
'Tis but thy name that is my enemy;
Thou art thyself, though not a Montague.
What's Montague? it is nor hand, nor foot,
Nor arm, nor face, nor any other part
Belonging to a man. O, be some other name!
What's in a name? That which we call a rose
By any other name would smell as sweet;
So Romeo would, were he not Romeo call'd,
Retain that dear perfection which he owes
Without that title. Romeo, doff thy name,
And for that name which is no part of thee
Take all myself.


What matters is what something is, not what it is called.

Pluto is still Pluto. It didn't change into something else because someone says it did. It might now be reclassified as a "Minor Planet" but that doesn't make one iota of difference to Pluto!

Answer 11

it is true...it is not big enough. I read about it in Time for Kids, so if you go to their website, you can read the article in terms the average person can understand. They are also concidering adding a new planet.

Anyway, the new phrase to remember the planets is, My very educated mother just served us nothing.
