what makes pluto loose its name as a planet?

Answer 1

They didn't want to go farther than Uranus.

Answer 2

It was a combination of things. It has a very unusual orbit, is very small and the astronomical gurus decided it just wasn't the stuff that planets are made of.

However, I went to college where the discoverer of Pluto, Dr. Clyde Tombaugh, was on the faculty, and Pluto will always be a planet to me. If Pluto isn't a planet why do we count another unusual planet--Mercury? Mercury is also small and has no significant atmosphere.

I say we all write our Congressmen and members of parliament or whatever we have and demand Pluto be reinstated in 2007!

Planet Pluto Now!!!

Answer 3

because Pluto is not a planet, Pluto is Santa's reindeer Hah. But Pluto is now a planetoid or something because it's orbit is irregular not like the other planets that's why its the 8th planet in some occasions because it overtakes Neptune. Or maybe the other planets were jealous because it has Charon for a Satellite and the Earth only has the moon. Or maybe because his the coolest among the planets.

Answer 4

The answer is NO. Here is why…

With recent change of definition of “planet”, we were told that there is a change of number of planets in our Solar System, so that it now has 8 planets, instead of 9. And we were told that Pluto lost its status as planet. But nothing of this happened.
With changing the definition of “planet”, what changed is what the word “planet” means. If we reserve the word “planet” for what it means today, we can use the term “old_planet” for what “planet” meant before the change. And having on mind that, we can say that, nothing in the reality changed concerning the number of planets, or number of old_planets. The Solar system still has 9 old_planets, and it has 8 planets. Actually it had 8 planets all along (given the definition of planet we have today). So the number of planets didn’t change at all, nor the number of old_planets changed. The number of planets can change only if some planet breaks in two, or if some neighboring system borrows us one planet, or if one of the planets self-destructs, and so on.
Also Pluto didn’t lose its status as planet, as it never was a planet. It only had status of old_planet.

Answer 5

1st and formost, there are confirmed 14 planetoids in our solar system that maintain their own independant orbits (Erise being the 10th planet). after re-discussion of what defines a "planet", it was found that Pluto is only a planetoid; in that it holds no inherent atmosphere, has no potential for being hydrostatic, maintains an irregular orbit, and does not maintain a revolution around its own central core. There are 4 moons of Jupiter that actually classify as planets, which are currently being discussed as such. As our knowledge as a culture grows, we need to be prepared to change what our previous labels were.

Answer 6

The orbit of Pluto was different from the other planets.

Answer 7

Here is an easy language answer

See now the definition of Planet is changed. Therefore it is now not considered to be a planet.
or,
It is the only planet which cuts the orbit of other planet (i.e. Neptune ). As a result , our ancestors thought it was a satellite. Therefore, experts thought not to go against our forefathers.

Answer 8

It doesn't meet the size and mass requirements to be a planet. And it's orbit intersects another planet's orbit, which is a no no for being a planet. It is all a matter of semantics. A rose by any other name would smell as sweet.

Answer 9

It is still Pluto, but about 200 members of the IAU decided that it did not meet the requirements of a real planet, so its status was downgraded

Answer 10

a planet must be able to
1) revolve around the sun
2) have its own satellites or moons...
3) be hydrostatic or have some hydrostatic abilities
and the 4th one i can't rember but somehow pluto some how neva met the no. 1 they tot it did for years, but pluto is just a big snowball floatin in our universe. u shuld research more into it, i read these ones months ago

Answer 11

PLUTO IS ACTUALLY ONE OF THE MOONS OF NEPTUNE.
IT WAS CONSIDERED AS A PLANET BECAUSE ITS MOON CHARON ORBITS IT. BUT ACTUALLY BOTH PLUTO AND CHARON ORBIT NEPTUNE. SO NATURALLY, PLUTO IS A MOON AND NOT A PLANET!!
