is pluto a planet or a moon?

Question

is pluto a panet or a moon now

Answer 1

It is a dwarf planet.

Answer 2

There is only one Moon, and it is that silvery globe that entices lovers and ruins the night sky for stargazing. Some people have extended the word "moon" to mean any satellite, but saying that Io is a moon of Jupiter is like saying that George Bush is the George Washington of the United States of America.

Pluto is neither a planet nor a planetary satellite. It is not a satellite since it does not revolve around another body. Both Charon and Pluto revolve around a barycenter that is outside Pluto's globe, so some say that this is a double dwarf planet. And that is what Pluto is now - a dwarf planet. It is too small to be a planet, and it does not dominate its orbit.

pluto is not a planet, but pluto orbits the sun, is round, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite so it is a dwarf planet. this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.

this same thing has happened before. beginning in 1800, astronomers found a few bodies orbiting between the orbits of mars and jupiter, and they finally stopped calling them planets after the fourth discovery. astronomers then added numerals to the names, and pluto recently got its numeral. 150 years from now, no one will think of "134340 pluto" as a planet. very few will even know we classified it as a planet. "1 ceres" and "136199 eris" are other dwarf planets.

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 illogical and "out of place". this was the right thing to do, believe me. i don't understand why so many are having such a problem with this.

i don't know how long this will drag on tho. many planetary scientists are not satisfied that the definition is rigorous enough.

Answer 4

pluto now is neither a planet nor a moon. Its a dwarf, a heavenly body big enough to have independent existence and small enough not to be called as a planet. As far as being a moon is concerned, it should be revolving round a planet which it does not. Hence its a dwarf

Answer 5

It is a planet - Read-

Pluto (officially designated 134340 Pluto) is the second-largest known 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 water 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 planetoid/moon combinations in the solar system, and because the barycentre of their orbits does not lie within either body. 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 of 2006 the International Astronomical Union (IAU) redefined the term "planet", and classified Pluto, the asteroid Ceres, and Eris as dwarf planets. Pluto is also classified as the prototype of a family of trans-Neptunian objects. After the reclassification, Pluto was added to the list of minor planets and given the number 134340

Answer 6

It is supposedly dwarf planet. I don't think so because Pluto itself has moon the revolves around it Charon. It is not a moon. But now it is classified as a dwarf Planet.

Answer 7

It never was and never will be a moon, as moons orbit planets. Pluto orbits the Sun, not a planet. It is now being called a dwarf planet.

Answer 8

Pluto is a dwarf planet now.

Answer 9

The IAU recently re-classified Pluto as a dwarf planet, but in my book, it's still one of the nine planets.

Answer 10

Neither...it is a Dwarf Planet...according to the IAU.

Answer 11

It is a dwarf planet. Very simple.
