Is there a planet X?

Answer 1

No. The only named planets are the standard 8, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

If you mean "Is there another planet orbiting the Sun that has not yet been found?", the answer is "we don't know."

If you mean is there some big planet rushing toward Earth from the far reaches of the solar system with a name beginning with Nibiru or whatever the flavor of the month is, again, we don't know, neither do the doomsday prophets. It is unlikely, since big things can be spotted by their gravitational effects on little things and no such gravitational effects have yet been noticed, even if they do exist.

If you mean the "Planet X" of Percival Lowell and Clyde Tombaugh, the answer is no. Lowell chased a phantom planet based upon some bad orbital calculations for Uranus and Neptune. Tombaugh found Pluto while looking for 'X', but Pluto was just a byproduct of a wild goose chase (he found a sparrow while looking for the goose).

I hope I came close, somewhere in the above, to answering your question.

Answer 2

its a hypothetical planet. The X represents an unknown

they where thinking maybe there was a planet beyond Neptune (at the time) , But since they didn't have a name for an object they haven't even seen, they used X as a variable.

.... the search for "planet X" still continues.
meaning we keep looking for new planets.

The original theory : to explain discrepancies between the calculated and observed orbits of Uranus, Saturn, Jupiter and Neptune.

Pluto was then discovered. BUT we can see that its mass is not enough to have a gravity that could affect the above listed planets.

After Voyager 2 passed the above listed planets, Recalculations where done on their mass and gravity with the new technology and up close visit. The discrepancies vanished with the updated statics. Also, to date there are no discrepancies in the trajectories of any space probes

Recently we've discovered a dwarf planet we named Eris out there beyond Pluto and the kupier belt. Unfortunately, once again, Eris doesn't have enough gravity to effect the planets either.

Some people claim it could be a comet that disturbs the planets orbits, but I think thats stretching it, since there is no more evidence the planets ARE disturbed.

It IS the NEXT hypothetical planet. (or dwarf planet, whatever)

The idea of nibiru started about 3800 years ago (1800 BC). Before we had telescopes ya know.... you might as well ask if heaven is real.

but the idea of it has been revamp by someone who might be alittle bit ,.... mmmm crazy?

the claim is
a brown dwarf
http://en.wikipedia.org/wiki/Brown_dwarf
with a planet circling it named nibiru, came through OUR solar system

nibiru's moon smacked into a planet and destroyed it causing the asteroid field.

if a brown dwarf and a planet with a moon came running through our solar system. We'd have a bigger mess than just an astroid field.

The sun or even jupiter (their brown dwarf is supposed to be 10 times SMALLER? than jupiter) would capture this star and the planet might not even remain in orbit around the brown drawf.

the idea of nibiru is ridiculous.

Answer 3

There are many bodies in the Solar system. The problem is what qualifies to be called a planet. The first eight are pretty much clear cut in their substantial size and regular orbit around the Sun. The next few (included the recently disqualified Pluto), are borderline , and a whole lot more just flowing bodies. Again , according to the current IAU definition, no, we don't have planet X.

Answer 4

im assuming your talking about nibiru. some used to think it was a failed star (brown dwarf) orbiting out sun at about 1 lightyear away. no it doesnt exist, it was thought up nearly a century ago.

the other planets people are talking about are dwarf planets, like pluto. they are simply objects past pluto in an area called the kuiper belt. they are too small to be considered planets. none of these could be nibiru because they are all dwarf planets, nibiru would be a planet much more massive than jupiter.

we have been able to directly image planets that are lightyears away. nibiru would be a very large planet only about 1 light year away, we could notice it. and we havent yet, nor will we ever, because it does not exist.

Answer 5

Yes, Planet x is behind pluto and it had the same characteristics as pluto, it is compleate ice, then planets y, and z were found then 23 other revolving our sun made off of ice so pluto is nolonger considered a planet

Answer 6

dude havent u heard tht there are only 8 planets in our solar system

there obviously is no such thing b/c if there was then we would 've found it by now b/c we 've hubble space telescope tht detected there are water molecules in a planet tht was 20 light years away and this is in our solar system so i think it would 've done its job if it existed

Answer 7

yes. i think is behind Pluto.

Answer 8

not that I know of.
