Is there really a planet in space called planet X?

Answer 1

There is much confusion about the name "Planet X" with the following contenders all using the same terminology:

(a) a hunt for a trans-Neptunian planet postulated by Percival Lowell 100 years ago as being needed to explain discrepancies in the orbit of Neptune. i.e. the same process as led Urbain Le Verrier to postulate a trans-Uranian planet as being needed to explain discrepancies in the orbit of Uranus, which led to the discovery of Neptune in 1846. In this context "X" means an unknown, as in algebra.

Lowell's (re)search has been abandoned because better estimation of Neptune's mass as a result of the Voyager I and II flybys has meant the perceived discrepancies disappear and no unknown planet is therefore needed to explain non-existent discrepancies!

(b) The recent discovery of Xena was hailed as a tenth planet by NASA but the IAU chose to ignore the pressure put on it to give planetary status to an object bigger than Pluto and called them both dwarf planets in preference. In this context "X" means the Roman numeral for ten as well as echoing the name "Xena"

(c) Nibiru (from Babylonian mythology)

(d) Wormwood (mentioned in the Bible)

These latter hypothetical planets, both claimed to be harbingers of doom, are promoted by mystics who prophesy they are about to return imminently (they allegedly have been here before) but ask one "okay, where are they at the moment, then?" and the idea of predicting astronomical events by making observations, taking photographs and calculating orbits is obviously an entirely new concept for them.

The assertion that they are on their way is apparently sufficient for an unquestioning mind and all it needs to be told!

They simply don't know where their doom planet is right now, and an injection of science into superstition leaves them conceptually out of their depth.

The obvious conclusion is that Nibiru and Wormwood do not exist. If their adherents cannot state a position in an orbit, and the world's astronomers have reported no sightings of them, then all the huffing and puffing and threats of "I will blow your house down" (the earth is supposed to stop rotating when they arrive!) won't make the slightest difference as regards the prophecies being fulfilled.

The three little pigs need to call the mystics' bluff and say to the Big Bad Wolf at their door: "Sorry. Don't believe you. Come back when you have got a planet to show me, and an orbit and a NASA risk assessment of the likelihood of an impact!"

Answer 2

I don't think so... If X means 10th, there are some facts to be considered:
1.- Pluto was no more the 9th planet. Now is a dwarf planet
2.- There are some dwarf planet after Neptune. Eris is the largest, a little larger and 3 times farther than Pluto to the Sun. Actually the Hubble Telescope is capable to find a planet (as large as the Earth) maybe 6 times the distance of Pluto.
3.- The real planets have orbit near circular, and near the same plane of the other planets.
4.- A planet in an orbit farther than Eris is improbable to be formed because there the space would have much less matter than the available when Neptune born.

Answer 3

There are 8 planets. Ceres, Eris, and Pluto are identified as "dwarf planets" although many objects within the solar system (including kuiper belt and oort cloud) are similar in size. For example, Sedna, a newly discovered "planetoid" is about 3 times as far away from the Sun as Pluto, and roughly the same size.

There is (I have gathered from reading certain websites) a sort of "cultish" following to this Planet X. I didn't realize how widespread this was until I actually met a guy who was all about this (he'd evidently stumbled on some planet x web pages and actually believed the stuff). these people have some extremely wacky ideas and they're real serious about it, too. I would stay away from these ppl if I were you.

Answer 4

A real planet, no. A hypothetical one, yes.

Planet X is the name that was given to the hypothesized planet past Neptune. The planet's hypothesized existence was based on mathematical calculations related to Neptune's behavior. Pluto was originally believed to be this mystery planet, however, the mass of Planet X was significantly larger than that of Pluto's. No body has been found past Neptune that fit the bill for Planet X, so it is still just a theory.

Answer 5

Planet X and Nibiru are actually not the comparable ingredient. in case you look into the historic previous of Astronomy you will see that astronomers could desire to no longer clarify the plain perturbations of Neptunes Orbit and so got here up with a thought a pair of Planet X int eh Outer image voltaic equipment. Searches for this planet led tot he discovery of Pluto yet because it grew to become out Pluto became some distance to small to account for the diversities in Neptunes Orbit. properly as technological know-how stepped forward, so did the orbital calculations of Neptune and there have been blunders interior the previous calculations - ie no perturbations and subsequently no planet x. If there became this way of planet then it woudl be detected by making use of unexplained differences interior the orbits of the outer planets, dwarf planets and KBO's. yet there are not any disturbances! Nibiru is myth - there is nor has there ever been any scientific info for it extremely is existance.

Answer 6

Scientists called the hypothetical "tenth planet" Planet X for a while, after Pluto was discovered. For various reasons, there was some evidence to suggest another Neptune-sized planet orbited past Pluto.
But good Hubble and Spitzer telescope images, infrared observations, and scans by the Voyager and Pioneer spacecraft have eliminated that particular planet as existing (as far as we know).

So the short answer - no.

Answer 7

There are actually 11 planets,but 3 are minor.The 3 minors are Crete,Pluto,and Xena.Xena is 9 billion out there,and was almost considered a planet before Pluto wasn't.Crete is just the largest asteroid in the asteroid belt.Xena might be what some people consider Planet X,but anything different then that is nonexistent.

Answer 8

Hi. From the web: "Planet X is a large hypothetical planet with an orbit beyond that of Neptune. The scientific basis of the Planet X hypothesis was broadly discounted in the early 1990s and today no significant portion of the scientific community believes it to exist."

Answer 9

No, there is not. Nasa confirms there is no Planet X, it was just a way to explain some things. Check out the links belooow! and the ones inside it!

Hope it helps!

Answer 10

Yes. It comes right before the planets Y and Z.
