Why have astronomers decide that Pluto should be reclassified as a dwarf planet?

They agreed a new definition of a planets and created "dwarf planets" as a separate type of object. Pluto qualified only as a "dwarf planet", because it is not the dominant object in the neighbourhood of its orbit.

When and who reclassified Pluto as a dwarf planet?
In the year 2006.Pluto was demoted because it did not have an orbit of its own, but shared its orbit with other Kuiper belt objects (KBOs).(The link below should help answer your question better)
What is Pluto called now?
It is still known as Pluto, even though it was downgraded to a dwarf planet and given a number. So really we should call it 134340Pluto.
Should Pluto be a planet again?
I don't think so because we are discovering more Pluto like bodies in the solar system and we either have to make these planets or put Pluto into a new category (of Dwarf Planets) along with these.
How should you humans react to martians if they decide to visit planet earth?
They should warn everybody about that martians are coming.Then they should go in the house close the door and the windows and hide.Then they should have weapons if the martians are bad.
Why are some planets called Dwarf Planets?
A dwarf planet is called a dwarf planet as it is small. Another reason is that people such as astronomers , think that because a planet is so small it should not be in our solar system. That is quite silly you know because if a planet is there, a planet is there! Comment: Unfortunately that's really not the proper explanation.

Some astronomers think Pluto should not be called a planet because it?
Pluto is too cold to be a planet Pluto is made completely out of ice
Why don't astronomers think Pluto should not be called a planet?
Pluto has been the ninth planet in our solar system ever since it was discovered. However, as a small rocky planet with a very strange orbit, it doesn't really fit in with the rest of the gaseous outer planets. Pluto is much more similar to a group of objects called Trans-Neptunian Objects (TNOs), or asteroids. So, some astronomers don't think Pluto should be called a planet.The International Astronomical Union (IAU) gets to decide questions for astronomers around the world. They have been talking about Pluto's status, and what it should be called. Since Pluto is very important to a lot of people, the IAU isn't going to take away Pluto's status as a planet. They are talking about calling Pluto both a planet and a TNO, but Pluto still is and will be a planet!
What planet disappeared?
No planet actually disappeared. A couple of years ago, there was agreement among most professional astronomers that Pluto should not be considered a major planet. It is no longer listed as a major planet of our solar system, but it is still there.

The current portion of long-term debt should?
be reclassified as a current liability
Why do some astronomers think Pluto should not called a planet?
they think that it's too small to count for anything. :( really stupid but whatever. ~josette :) hope it helped a bit!

Why do you say that Neptune the planet was discovered by pen?
It's a long story, and to answer it, we have to go all the way back to when Uranus, the planet before Neptune, was discovered. Uranus was discovered in 1781, and astronomers started calculating the orbit it should be following around the Sun. However, within a few years, astronomers started noticing the planet wasn't quite following the orbit they'd assigned it; it was slightly out of place. No matter how hard they tried, the mathematicians couldn't manage to calculate an orbit for Uranus that fit the facts. In 1845, two astronomers, John Couch Adams in England and Urbain LeVerrier in France, working independently of each other, came to the conclusion that there must be another planet beyond Uranus, pulling on it with its gravity and affecting its orbit. They used the discrepancies in Uranus' orbit to calculate where the new planet should be, but couldn't get anyone interested for a long time. It wasn't until 1846 that a German astronomer, Johann Gottfried Galle, using LeVerrier's calculations, decided to look at the spot in the sky LeVerrier had predicted the planet should be - and lo and behold, there was Neptune! So Neptune was discovered by Adams and LeVerrier, writing down their calculations with a pen, before astronomers had ever actually seen it. That's why Neptune was "discovered by pen."
Why do you think scientists found it difficult to decide how Pluto should be classified?
because not all scientists agreed with each other so it took alot of research on the planet Pluto
