is pluto a planet????and plz give the name of other 3 planet??

Answer 1

Was'nt that Mickey Mouse's dog?

Answer 2

Pluto is smaller than 7 of the moons in the Solar System. Because it is so small many scientists don't consider it a planet at all. In 1999 a group of scientists attempted to redesignate Pluto as a comet. On August 24th, 2006 Pluto's status was officially changed from planet to dwarf planet. For decades children have been taught that there are nine planets in the Solar System. However, with this change, there are now only eight planets.

other planets are:
MERCURY
VENUS
EARTH
MARS
JUPITER
SATURN
URANUS
NEPTUNE

Answer 3

Pluto is one of the nine objects that were considered planets in the 20th century. The other three objects that would have been the tenth through twelfth planets under rules proposed this year by the International Astronomical Union are Charon, a moon of Pluto; the asteroid Ceres (which was considered a planet in the 19th century); and "Xena", or 2003 UB313, the farthest known object in the solar system.

According to an AP article: "But the IAU said Pluto meets its proposed new definition of a planet: any round object larger than 800 kilometers (nearly 500 miles) in diameter that orbits the sun and has a mass roughly one-12,000th that of Earth. Moons and asteroids will make the grade if they meet those basic tests."

Shortly after that, they reversed themselves and dubbed Pluto and others "dwarf planets", which pretty much means any round object orbiting the Sun that isn't a moon.

Answer 4

as before few days the scientists desided to take the word planet away from pluto due to few reasons. One is that the size of pluto is very small, that is less than that of our moon, secondaly the orbit in which the pluto is getting to sun's gravitational field is elliptical like which is different from any other planet. The other three planets which are under consideration to be a planet are the moon of jupitor, one small planet between mars and jupitor, the third one is pasidon. Hoping you got it right.

Answer 5

Pluto, long known as one of the nine planets of the solar system, was stripped of its planetary status when leading astronomers decided to redefine it as a "dwarf planet".

After a week of contentious debate, astronomers from around the world at the International Astronomical Union (IAU) General Assembly in Prague, yesterday decided to demote Pluto from planet to dwarf planet, downsizing the solar system from nine planets to eight.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune will now be defined as "classical planets."

The IAU said in a statement that the definition for planet is now officially "a celestial body that orbits around the sun; has sufficient mass to become round; and has "cleared the neighborhood around its orbit."

So as for example, Jupiter, which circles the sun is supreme in its own orbit, is a planet.

But Pluto, on the other hand was disqualified as its oblong orbit overlaps with Neptune's.

The new definition of celestial bodies also lays out a third class of lesser objects that orbit the sun - "small solar system bodies," a term that will apply to numerous asteroids, comets and other natural satellites.

Answer 6

Wow Pluto in now bonsai

Pluto, which was discovered in 1930 by the American Clyde Tombaugh, will be referred to as a "dwarf planet

The scientists agreed that for a celestial body to qualify as a planet:

it must be in orbit around the Sun
it must be large enough that it takes on a nearly round shape
it has cleared its orbit of other objects
Pluto was automatically disqualified because its highly elliptical orbit overlaps with that of Neptune. It will now join a new category of dwarf planets.

Answer 7

pluto isnt a planet nemore. it ws stripped f d status recently. The other three planets of same type as pluto : Charon( previously thought as pluto's moon, bt always doubtful as it ws about half d pluto's size.), Ceres( an asteroid in kuiper belt b/w mars n Jupiter) n Xena.

Answer 8

Yes - Pluto is a planet - and there are more than 3 other planets - earth/venus/uranus!@

Answer 9

pluto was supposed to be a planet a few days back but until recently it has been outcast from that family due to weird knowledge of our so called scientists. the other planets are our very own mother earth(dont know for how many more days),mars,mercury,venus,etc.

Answer 10

Pluto (officially designated 134340 Pluto) is the second-largest known dwarf planet in the solar system, orbiting between 29 and 49 AU from the Sun. 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 2003 UB313 (nicknamed "Xena") 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 2003 UB313 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]

Total planets as per latest records are:

Mercury ( ) with no confirmed natural satellites
Venus ( ) with no confirmed natural satellites
Earth ( ) with one confirmed natural satellite, the Moon
Mars ( ) with two confirmed natural satellites, Phobos and Deimos
Jupiter ( ) with sixty-three confirmed natural satellites
Saturn ( ) with fifty-six confirmed natural satellites
Uranus ( ) with twenty-seven confirmed natural satellites
Neptune ( ) with thirteen confirmed natural satellites

Answer 11

Ploto is no more a planet. It was a planet but then suddenly some day it went to the orbit of netune's and then became a white dwarf. The four new planets are (you are wrong, it's not three but four):Sedna, Quaoar, UB313 and Ceres.
