134340 Pluto was discovered on Februrary 18th 1930 by the American astronomer Clyde W Tombaugh after a search lasting some 20 years occasioned by the fact that Neptune's orbit was being influenced by the gravitational pull of another object.
Tombaugh worked at the Percival Lowell Observatory in Fiagstaff, Arizona. It was Pickering and Lowell who had begun the search in 1909 using the observatory Lowell had founded in 1894.
Part of Tombaugh's ashes are aboard the New Horizons spacecraft currently on its way to Pluto, due to arrive in July 2015.
It was originally thought to be larger than th earth, and that is why there was no hesitation in pronoucing it to be a planet. But it was later realised this was a wrong impression and in August 2006 the IAU took away the planetary status it had bestowed 76 years previously.
Once no longer a planet, it was given a Minor Planet Centre number 134340
134340 Pluto is the second-largest known dwarf planet in the solar system and the tenth largest observed body directly orbiting the Sun. It orbits between 29 and 49 AU from the Sun, and was the first Kuiper Belt Object to be discovered. (We now know of some 800+ KBOs),
Approximately one-fifth the mass of the Earth's Moon, Pluto is primarily composed of rock and ice. It has an eccentric orbit that is highly inclined with respect to the planets and takes it closer to the Sun than Neptune during a portion of its orbit.
As you sound as though you are of school age yourself, the story of how Pluto got its name may interest you?
The name Pluto was first suggested by Venetia Burney (later Venetia Phair), an eleven-year-old girl from Oxford, England.
Venetia, who was interested in Classical mythology as well as astronomy, suggested the name, the Roman equivalent of Hades, in a conversation to her grandfather Falconer Madan, a former librarian of Oxford University's Bodleian Library.
Madan passed the suggestion to Professor Herbert Hall Turner, Turner then cabled the suggestion to colleagues in America.
The object was officially named on March 24th 1930. Each member of the Lowell Observatory was allowed to vote on a shortlist of three: "Minerva" (which was already the name for an asteroid), "Cronus" (which had garnered a bad reputation after being suggested by an unpopular astronomer named Thomas Jefferson Jackson and Pluto. The first two letters of Pluto's name, PL, are Lowell's initials.
Pluto received every single vote. The name was announced on May 1, 1930. Upon the announcement, Madan gave Venetia five pounds as a reward.
Five pounds is less than a week's pocket money now, but then it was more than a weekly wage for many people,
Pluto takes just over ninety thousand earth days (90,613.3055 days to be precise) or almost 250 earth years (248.09 years to be precise) just to go round the sun once. With the Pluto year being that long no human born in a colony there would ever have a birthday party: no-one would ever reach their first birthday!

It is named after the roman god of the underworld. It is so far that a only little amount of light can reach it. It was discovered by Dr. Clyde Tombaugh. It was denoted as a planet because:
On Aug.19, 2006, the International Astronomical Union ( 2,500 astronomers from 75 countries) defined the word planet.
Planet
1. orbits the sun
2. large enough to assume a circle shape
3. Clears its orbit from neigboring planets
since Pluto passes through the orbit of neptune, it was denoted as a planet. it became a dwarf planet with:
1. Pluto
2. Ceres
3. UB313
note: it is still a member of the solar system and i am only 11 years old

It's a dwarf planet now. It is smaller than our moon, has a moon that is so big compared to pluto itself, and so close to it in orbit, that gravity kicked in much in the same way that it did between our sun and jupiter - pluto's barycentre is, as the sun's barycentre, outside of it's body and so it circles around that as well as being in orbit around the sun. The sun, of course, doesn't have any orbit - in case you were thinking of using that comparison... well, no orbit that we can discover anyway. Not in our lifetime.
It has two other moons, called Nix and Hydra. The closest moon to Pluto is called Charon... incidentally all names that relate to the underworld.
Pluto has a very elliptic orbit - at one point he would be (since the new act on planets) the 9th planetary object in a row (mercury-venus-earth-mars-ceres(dwarf planet)-jupiter-saturn-uranus- THEN pluto-neptune-eris(dawrf planet)). At his point farthest away from the sun, he would be the 10th. Coming only after Neptune.
Pluto also has an orbit very inclined to the ecliptic, which is very unusual for a planetary object - one reason why they *finally* decided to demote it to a lesser planetoid.
Now I know my explanations usually make feck-all sense, so here's a link to more information.

Basic Training of the Puppy - Read here https://tr.im/7q5sH
The new puppy is certainly one of the most adorable and cuddly creatures that has ever been created. It is the most natural thing in the world to shower it with love and affection. However, at the same time it is important to realize that if you want to have a well trained adult dog, you need to begin the training process right away. The dog, like its related ancestor, the wolf, is a pack animal. One of the features of a pack is that it has a single dominant leader. Your new puppy is going to want that leader to be you, but if you do not assume that role from the very beginning, the puppy’s instincts will push him to become the leader.
The most important thing to remember about training the puppy during its first six months of life is that it must see you as the leader of the family pack. The essential thing is gaining the trust and the respect of the puppy from the beginning. You will not do this by allowing the puppy to do whatever it wants to do whenever it wants to do it. On the other hand, a certain amount of patience is required. Most people err in their early training by going to extremes one way or the other. Although you need to begin the basic training process at once, you can not expect your dog to do too much at first. Basic obedience training is fine and should include simple commands like sit, stay, and come. Remember that trying to teach the dog advanced obedience techniques when it is a puppy is much like trying to teach a five year old child algebra.
It is also important to restrain from cruel or abusive treatment of the puppy. You can not beat obedience into your dog, and it certainly is not going to engender feeling of respect and trust. House breaking is an area where this usually becomes a problem because of the anger that is triggered when the puppy fails and creates a mess inside the home. Although this issue must be addressed without anger, it most be addressed. If you allow the puppy to eliminate inside the house, it will continue to do so as an adult dog. The same thing is true of other destructive or dangerous behavior such as chewing and biting. Do not expect the puppy to grow out of it. You are going to need to train the puppy out of it, but you should do so firmly but with a sense of play and fun using positive reinforcement and lots of love and praise for good behavior.

ickey's faithful pet dog Pluto starred in 48 of his own cartoons, but also appeared along with Mickey Mouse and Donald Duck in many of their cartoons. Pluto was created as an actual dog character, with no speaking voice, as opposed to Goofy, who was created as a human character. The dog who would eventually evolve into Pluto made his debut as a bloodhound in the Mickey Mouse cartoon "The Chain Gang" in 1930. Later that year he appeared as Minnie Mouse's dog, Rover, in "The Picnic," and the following year finally became Mickey's dog Pluto in "The Moose Hunt." Favorite sayings: "Grrr ..." "Snort!" "Sniff, sniff, sniff ..." "Bark! Bark!"

You cannot find ANY information about Pluto? Excuse me, but either you are incredibly lazy or incredibly stupid. Either way, you ought to learn the skills to do your own homework.
