what is "pluto" ? Explatation of pluto?

Answer 1

http://en.wikipedia.org/wiki/Pluto

pluto does orbit the sun, is ball-shaped, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite so it is not a planet. this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially. i don't know how long this will drag on tho. many planetary astronomers are not satisfied that the definition is rigorous enuf. i can accept that the definition is flawed, but i can not accept that pluto is a planet.

many astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system. they are called nix and hydra.

i have been waiting for this since i was about twelve. i feel somewhat satisfied. i knew that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly. it just felt "out of place". now that astronomers have found hundreds of other bodies with similar orbits, classifying "134340 pluto" as a planet is even more irrational. this was the right thing to do, believe me.

incidental, "134340 pluto" was never a moon of neptune. neptune did capture triton. this is why triton has a retrograde orbit.

Answer 2

Pluto, the last planet to join the heavenly pantheon, became the first to leave it. The status of Pluto had been under discussion for some time, but with the discovery of 2003 UB313, nicknamed Xena, the question became acute, for it seemingly had as much right as Pluto to be called a planet.

On August 24, 2006, the International Astronomical Union surprised the world by voting in a new definition of planet, one that would exclude Pluto and bring the total number down to eight. (There had previously been been strong speculation that the redefinition would bring the total up to 12 instead of down.)

Pluto was instead classified as a dwarf planet, along with Ceres and the aforementioned Xena. The main difference between a dwarf planet and the real thing is that the dwarf variety has not cleared the area of its orbital path.

This redefinition met with a wave of protests from those who wanted to see the ninth planet grandfathered in, including but not limited to supporters of the late Clyde Tombaugh, who discovered Pluto in 1930. His widow, however, said he would have been accepting of the IAU's decision since "he was a scientist" and understood that astronomers had to take into account newly discovered objects in the Kuiper Belt (where Pluto is located).

But opponents of Pluto's demotion remain unconsoled and have generated a thriving industry in T-shirts, mugs and other memorabilia. Among the many slogans of this movement was one which played on the mnemonic for the names of the erstwhile nine:

Answer 3

Pluto, officially designated 134340 Pluto, is the second-largest dwarf planet in the solar system. It orbits between 29 and 49 AU from the Sun, and was the first Kuiper Belt Object to be discovered. 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. Pluto and its largest satellite, Charon, have often been considered a binary system because they are more nearly equal in size than any of the other known planetoid/moon combinations in the solar system, and because the barycentre of their orbits does not lie within either body. However, the International Astronomical Union (IAU) has yet to formalize a definition for binary dwarf planet, therefore Charon is regarded as a moon of Pluto for now. Two smaller moons, Nix and Hydra, were discovered in 2005. Pluto is smaller than several of the natural satellites or moons in our solar system (see the list of solar system objects by radius).

From its discovery by Clyde Tombaugh in 1930, Pluto was considered the ninth planet from the Sun. In the late 20th and early 21st century, many similar objects were discovered in the outer solar system, most notably the Trans-Neptunian object Eris which is slightly larger than Pluto. In August 2006 the IAU redefined the term "planet", and classified Pluto, Ceres, and Eris as dwarf planets.[1] Pluto is also classified as the prototype of a family of trans-Neptunian objects.[2][3] After the reclassification, Pluto was added to the list of minor planets and given the number 134340.[4][5]

Many moons ago, when the internet was not yet invented, and children were seen as prone to question others as to the nature of the universe, elders would answer, and not see this as anything but normal. Of course, you can ask, and search the engines available. The truly called to astromomy will not stop there. I am so old that I do not remember when Pluto was not a planet, or is that young? Pluto was discovered and seen as another planet, when people still unwrapped their gifts with the adoration of a child.

Answer 5

pluto? a planet pluto or pluto, a disney character? (lol)

Pluto orbits beyond the orbit of Neptune (usually). It is much smaller than any of the official planets and now classified as a "dwarf planet". Pluto is smaller than seven of the solar system's moons (the Moon, Io, Europa, Ganymede, Callisto, Titan and Triton).

orbit: 5,913,520,000 km (39.5 AU) from the Sun (average)
diameter: 2274 km
mass: 1.27e22 kg
Pluto is too faint to be seen with the naked eye. When viewed through a telescope, it looks like a star.
Stellar occultations have revealed a tenuous atmosphere on Pluto composed primarily of nitrogen and methane gas.
Pluto is cold: -233° C (-390 ° F), just 40° C (72 ° F) above absolute zero. At this temperature, all elements would be frozen but neon, hydrogen, and helium.
Measurements indicate Pluto is the smallest planet, 2320 kilometers (1440 miles) in diameter. It is smaller than Earth's Moon.

Answer 6

Pluto was a cute little planet. Until those overpaid solar scientists who are so bored with twiddling their fingers and have nothing better to do so they suddenly invented this nonsense about downgrading poor Pluto to some dwarf planet. Very soon each of the planets will have their own little categories like Giant Planet, Big big Planet, Big Medium Planet, Big dwarf planet.... It is obscene that Earth already has so many bigger problems but these twiddling scientists (who really are paid a lot) spout their nonsense about downgrading a planet. Those scientists, NASA and all these flamboyant big spending ET projects should be shelved.

Answer 7

pluto is a dwarf planet thought to be made of ice and rock, which lies in a part of our solar system cluttered with similar (but usually smaller) icy bodies. it was probably formed when debris left over from the formation of the solar system achieved escape velocity from the sun's gravity, then colided with other debris and was again caught in the sun's gravitational pull.

Pluto is thought to have a thin frozen atmosphere composed of mostly methane (much like our own atmosphere). pluto has a very odd orbit that is eliptical and tilted compared to the orbits of the 8 real planets...

Answer 8

Pluto is now defined as a "dwarf" planet, since it fails to meet all the recently developed requirements for a planet.

Answer 9

Pluto is something the IAU made up so that 600,000,000,000,000,000 fools could ask about it on this website over and over and over and over and over and over again because they're too lazy to use the Search button.
