Which is the nineth Planet?

Answer 1

not yet discovered

Answer 2

There are now only 8 classic planets according to the International Astronomical Union. But Pluto is still a kind of planet that fits two of the most important criteria of being a planet (being round and orbiting the sun). Ceres, was an asteroid, but is actually spherical so gets upgraded to a kind of planet called a dwarf planet. The reason Pluto is not a classic planet is that there are at least another ten objects that are the same size as Pluto or even bigger. These Plutonian objects are not really like any of the other classic planets. Pluto is regarded as the prototype of a new family of dwarf planets.

Answer 3

Pluto is the ninth planet from the Sun in our solar system. Because Pluto is also the smallest planet in our solar system and has a highly eccentric orbit (which takes it inside the orbit of Neptune) there has been some debate regarding whether Pluto should be classified as a planet

Answer 4

Pluto

Answer 5

Actually, until last week it was PLUTO. Now the scientists have excluded PLUTO from the Planet Club. PLUTO is no longer considered as a Planet.

Answer 6

It's called "Irving" and it orbits my left ear.

When Pluto was originally discovered (by Clyde Tombaugh, 1930), he could only estimate its size based on its brightness. Since it's coated with ice, it appeared much brighter than average, and Tombaugh thought it was about the same size as Earth.

Since then, astronomers have figured out that it's much smaller, and should never have been called a planet in the first place.

Answer 7

as per new rules(25 Aug,2006) there are only 8 planets in the solar system
this is the result of the request of few scientists to add 3 new planets (Xena ,Charon , ?????)

(new rules= a planet is a heavenly body which revolves around the star in an almost oval orbit because its own mass & gravity prevents it from deviating from its orbit)

as ploto does not have a suffient mass& gravity it is affected by gravity of other heavenly bodies

Answer 8

That would be Neptune because between mars and jupiter there's a dwarf planet called ceres. dwarf planet means that pluto would be put into a category of planets called dwarf planets which are similar to what has been termed "minor planets". there are three planets like that, Ceres, pluto and Xena (or UB313) so here's how it goes : sun-mercury-venus-earth-mars-c eres-jupiter-saturn-uranus-nep tune-pluto and xena.

Answer 9

Till 2 days back it was pluto.Now it is taken out after the meet at Prauge by astronomers.now there r only 8 planets.

Answer 10

Pluto

Answer 11

Pluto, at least it was up until recently. From what I have heard scientists are trying to disprove it as being a planet.
