what do u think about the recent elimination of pluto from the planets list?

Answer 1

I don't care what they say. Pluto is still a planet to me.

Answer 2

G'day Sweety,

Thank you for your question.

While I am annoyed at the decision, I can understand the reasoning.

Pluto was recently reclassified as a dwarf planet. Since the discovery of Pluto in 1930, controversy has surrounded its status as a planet.The discovery of other trans-Neptunian objects (notably 2003 UB313, nicknamed "Xena", which is even larger than Pluto) focused debate on Pluto and the definition of a planet, which led to the above IAU proposal.

The 2006 redefinition of "planet" by the International Astronomical Union (IAU) states that, in the solar system, a planet is a celestial body that:

* is in orbit around the Sun,
* has sufficient mass so that it assumes a hydrostatic equilibrium (nearly round) shape, and
* has "cleared the neighborhood" around its orbit.

A non-satellite body fulfilling only the first two of these criteria is classified as a "dwarf planet", whilst a non-satellite body non-satellite body fulfilling only the first two of these criteria is classified as a "dwarf planet", whilst a non-satellite body fulfilling only the first criterion is termed a "small solar system body" (SSSB). The redefinition has been criticized and remains controversial.

According to the definition there are currently eight planets and three dwarf planets known in the solar system. The definition does not apply outside the solar system, and so does not include provision for extrasolar planets.

I have attached sources for your reference.

Answer 3

Look Sweety, it's time you got over it and moved on. Pluto never was a planet, it was merely misclassified as a planet. Of the eight real planets, the first four are small, rocky planets and the last four are large gas giants. Pluto (and its companion Charon) are small chunks of ice. They don't fit in with the other two groups, but they are like some of the other junk floating around in that neck of the solar system. So get over it!

Answer 4

It actually makes sense to knock it off the list. Given the new definition of a planet, it would have forced astronomers to include our own moon as one. The cries of "what about rewriting the text books and the cost?", mean nothing. As we're better able to see out into our solar system, there would have been more inclusions into the planetary list, forcing us to rewrite the books anyway.
That conference actually danced around Pluto's planetary status anyway. It didn't quite knock it down into an asteroid so it's still a "sort of" planet. I'm sure Copernicus got beat up pretty badly when he decided to change things as well.

Answer 5

I guess I'm young, and I used to read a lot when I was a boy. I didn't learn about the solar system from schools, I learned it from books and encyclopedias when I was a boy. I learned about Pluto knowing along Charon they were a binnary system, and that they were too small compared to the rest. I've read about how much some scientists wanted to stop calling it a planet all throughout middel school. When Pluto was demoted, I actually though it took them a long time to finally make it official.

Answer 6

I'm honestly not sure then why was it added in the first place if they have removed it now!!! Does this show that whatever we believed is false??

I haven't heard of any elimination of Pluto from the planet list. Just like Poopsie Daisy had mentioned - is this true?

Answer 7

well it is crazy to think that for all these years they didnt realize that pluto wasnt a planet and this silly mistake will cost the world dearly


but i will keep pluto as the last one

Answer 8

When I was in grade school; the early years and it was a looooooonnnnnnggggg time ago, I remember my teacher telling us that although Pluto was called a planet, that scientists were arguing that point...

Answer 9

I DO wonder if there will be a muliti-million recall of textbooks. That would effect school district budgets, and, subsequently, local taxes.
Taxation without Pluto representation. That's a call to arms.

Answer 10

Oh man... I heard about the addition of 3 new ones, but did they seriously dump Pluto? I hadn't heard. That really stinks... poor Pluto.
