is there a nineth planet?

Answer 1

I believe pluto is still categorized as a planet, although the debate does re-surface from time to time.

At least one of Saturns moons has the characteristics of a captured planet.

If you venture out of the solar system I inhabit, there are a number of planets in other solar systems.


Addendum: OK, we've been serious for a while, and there are some good answers after my first entry, but I'm kind of surprised noone has mentioned Nibiru.

Addendum 2: Pluto and Neptune take turns being the ninth farthest planet from the sun.

Answer 2

Yes...its been known since 1930 that Pluto, named after the roman god of death, was our nin eth planet. However, there have been people debating that pluto doesnt deserve to be a planet for its size (Its smaller than most moons, And I recall its barely larger than ours!), its planet/moon ratio (Charon, one of its moons, is half the size of the planet. It is for that reason classified as a double planet system.) Its composition (The kuiper belt objects match its composition of methane ice to well, while other planets are mainly composed of helium and hydrogen, which is rare on pluto). However, astronomers debate that pluyto still deserves to be a planetfor many reasons, like the discovery of 2 new moons orbiting the planet, facinating astronomers even more with this tiny planet.

Also, as some people mentioned, there is an object that might become our tenth planet, though it is not yet. And Sedna, whoever said it, is a distant object almost 8 billion to 80 billion miles away, not our tenth "planet."

Answer 3

The ninth planet is Pluto, but there is now some heated debate about the definition of "planet" according to some scientists, there is at least one more planet beyond pluto, but other scientists think it's not truly a planet. Actually, according to some definitions, Pluto isn't technically a planet either.

Short answer - yes Pluto
Long answer - depends on how you define a "planet"

Answer 4

Looks like the astronomy community is having a meeting to decide that, actually. See below

But if we decide Pluto is a planet for sure, then we've got 10 more space rocks lined up to be called planets too. :(

Answer 5

Yes there is a ninth planet it is called Pluto and it is the coldest planet!!!

Answer 6

yes, it's called pluto.

First time we knew there was a ninth planet was in the late 19th century. In 1909, we narrowed down its position to several coordinates, and was first "seen" in 1930.

in 2015, a probe will pass next to it, if you still want confirmation.

Answer 7

Sedna is #10, beyond Pluto (#9)

Answer 8

yes, pluto is still the ninth planet, there is also now a tenth planet.

Answer 9

Yes,it's pluto

Answer 10

Yeah, that would be Pluto.
