	Hypothetical planet - Wikipedia, the free encyclopedia
		This hypothetical substellar object is not Nemesis, since its existence is inferred from a different set of data; however there is the possibility that both sets of data could be true for the same object.
		A planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of asteroids and meteorites.
		PSR 1829-10's planet, proposed by Andrew Lyne of University of Manchester on July 24, 1991, was retracted in 1992.

	List of hypothetical planetary bodies - Wikipedia, the free encyclopedia
		Hypothetical planetary bodies are planets, moons or planet-sized stars which are inferred to exist based on scientific evidence, but have yet to be proven or have been disproven.
		There are many planets and planetary bodies which have been proposed to explain apparent irregularities in other planets' orbits, or other observed effects within or outside our solar system.
		Planet X: Planet proposed by Percival Lowell to explain irregularities in the orbits of Uranus and Neptune.

	Hypothetical Planets
		In 1901, Gabriel Dallet deduced a hypothetical planet at 47 AU with a magnitude of 9.5-10.5 and a 1900 longitude of 358°.
		This planet was supposed to be 50.6 AU distant.
		This hypothetical "death companion" of the Sun was suggested in 1985 by Daniel P. Whitmire and John J. Matese of the University of Southern Lousiana.

		Neuhaeuser, R.; Feitzinger, J. Characteristics of Planet X are developed by examining the aphelion distances and orbital parameters of comets that are assumed to beinfluenced by the unobserved planet.
		Planet X's semimajor axis and orbital eccentricity are found by, respectively, averaging the apheliondistances and studying the orbits of certain transplutonic comets.
		The mass of the planet is calculated by extrapolating the densitydistribution of the primordial solar nebula.

		Planet X is a large hypothetical planet orbiting beyond the orbit of Neptune.
		First, as they passed each of the outer planets, the acceleration gained by the gravitational pull of the planet was used to refine the masses of those planets.
		In a few instances, Planet X is accompanied by planets named after other letters, such as Planet Q or Planet Z. The computer RPG Ultima II has a Planet X that must be visited to acquire an artifact.

	Hypothetical Planets
		In 1901, Gabriel Dallet deduced a hypothetical planet at 47 a.u.
		The new planet, later named Pluto, turned out to be disappointingly small, perhaps only one Earth mass but probably only about 1/10 Earth masses or smaller (in 1979, when Pluto's satellite Charon was discovered, the mass of the Pluto-Charon pair turned out to be only about 1/400 Earth mass!).
		This hypothetical "death companion" of the Sun was suggested in 1985 by Daniel P. Whitmire and John J. Matese, Univ of Southern Louisiana.

	Mercury (planet) - Facts, Information, and Encyclopedia Reference article
		The planet remains comparatively little-known: the only spacecraft to approach Mercury was Mariner 10 from 1974 to 1975, and only 40–45% of the planet has been mapped.
		During this time, the planet was volcanically active, and basins such as the Caloris Basin were filled by magma from within the planet, which produced smooth plains similar to the maria found on the Moon.
		The hypothetical planet was even named Vulcan, but in the early 20th century, Albert Einstein's General Theory of Relativity provided a full explanation for the observed precession.

	Comet Orbits Hint At New Planet, Scientist Says
		``The hypothetical planet is within the distance range where numbers of small planets are predicted, but the presence of a large object orbiting so far from the Sun would be surprising,'' Murray wrote.
		Murray found oddities in the comet orbits which he believes could be explained by the existence of a large object or planet in the part of space where the comets are coming from.
		Despite his belief that it is a planet, he is not ruling out other explanations for the clustering of the cometary orbits.

		The outer planets are Jupiter, Saturn, Uranus, Neptune, and Pluto.
		The planets move around the sun in fairly circular orbits (i.e., they are elliptical orbits with low eccentricity).
		Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions.

	Marduk - Wikipedia, the free encyclopedia
		In late Babylonian astrology, Marduk was connected to the planet Jupiter.
		As the ruler of the late Babylonian pantheon, he was equated with the Greek god Zeus (Latin Jupiter), hence the name of the planet.
		He was associated with the sun, similarly to Ra in Egypt.

		He used a "graphical method", from the residuals of Uranus, he derived elements for a trans-Neptunian planet: mean distance 52 a.u., period 375 years, magnitude fainter than 13.
		Lowell's first search for Planet X came to an end in 1909, but in 1913 he started a second search, with a new prediction of Planet X: epoch 1850-01-01, mean long 11.67 deg, perih.
		In 1915, Lowell published his theoretical results of Planet X. It is ironic that this very same year, 1915, two faint images of Pluto was recorded at Lowell observatory, although they were never recognized as such until after the discovery of Pluto (1930).

	THE SURMISE OF VULCAN
		In the last century, although, a flurry of serious speculations were circulating among world class astronomers about the possible existence of a planet not at the outer reaches of the Solar system but at the inner region of the planetary family, inside the orbit of Mercury.
		At one time it was believed that there was a planet even closer to the Sun than Mercury based on unexplained orbital perturbances observed in the latter caused by the gravitational influence of a supposed heretofore undiscovered object hidden in the Solar glare.
		It was already known that the point of planet Mercury's orbit closest to the Sun was progressively 38 seconds per century greater than would be predicted on the basis of Newtonian mechanics.

		The 1900 longitudes of those hypothetical bodies were 274 and 343 degrees, both with the very large uncertainty of 180 degrees.
		The inner planet had a period of 272.2 years and a longitude in 1904 of 200 degrees.
		Currently, Powell’s new planet should be in Leo, at magnitude 12, however Powell thinks it’s premature to search for it, he needs to examine his data further.

		The force suggests a presence far away and unseen, a large object that may be the long- sought Planet X. The last time a serious search of the skies was made it led to the discovery in 1930 of Pluto, the ninth planet.
		The discovery of new planets has, in the last two hundred years, owed more to the science of mathematics than it has to the design of bigger and better telescopes.
		The unaccounted-for mathematical irregularities in the orbits of the outer planets have prompted astronomers to speculate upon the existence of a further, undiscovered planet.

	Hypothetical Planets
		All in all, from 1908 to 1932, Pickering proposed seven hypothetical planets -- O, P, Q, R, S, T and U. His final elements for O and P define completely different bodies than the orginal ones, so the total can be set at nine, certainly the record for planetary prognostication.
		The new planet, later named Pluto, turned out to be disappointingly small, perhaps only one Earth mass put probably only about 1/10 Earth masses or smaller (in 1979, when Pluto's satellite Charon was discovered, the mass of the Pluto-Charon pair turned out to be only about 1/1000 Earth mass!).

		It has been conjectured, however, that a possible 10th planet remains to be discovered beyond Pluto, the planet whose orbit extends farthest from the Sun.
		This hypothetical planet is referred to as Planet X, and the reasons for the conjecture are as follows.
		Various attempts have been made, over the years, at predicting the size and orbit of a possible Planet X. Some astronomers have suggested that its mass would be that of three to five Earths and its orbit both highly elliptical and so distant that the planet would complete only one orbit in about 1,000 years.

		These low-mass planets are exciting to the Anglo-Australian Planet Search team because they all have small velocity amplitudes - that is the represent the detection of quite small "wobbles" in the parent stars due to these planets.
		The velocity of this wobble depends on the distance at which the planet orbits, and the mass of the planet.
		The other planets (in particular the terrestrial planets like the Earth, Mars and Venus) are far too small to produce a measureable effect on the Sun.

		Assuming that Planet X's return date coincides with the next Chinese Year of the Dragon and the Mayan End-Time Date, then at the present time it would be (12 X 344,074,074 =) 4,128,888,888 Miles distant from the Sun.
		In this Intra-Solar-System Scenario, where Planet X does not "cross" or "pass" over from one star system to another, when this Uranus/Neptune-sized Planet reaches the inner Solar System, it would become visible to the naked-eye at some point in time, perhaps at a distance of 2 trillion miles, midway between the Planets Neptune and Uranus.
		NOTA BENE -- "The Planet Of The Crossing" is intimately associated with the Jewish Passover, as a "Planet Of The Passing Over".

		I have a hunch, though, that the name will not stick, if indeed it was the name, simply because all the other planets are named after mythological figures and some consistency in naming is always in order.
		Careful searches, including an infrared sky survey by the IRAS satellite, have produced no evidence of the hypothetical Planet X. Some astronomers believe that the observed orbital irregularities which prompted the search for X were due simply to observational error in the "old" (say, pre-1900) data.
		Others object on theoretical grounds, claiming that a planet as massive as the hypothetical Planet X (4 or more Earth masses) just could not have developed so far out in the solar system.

		In some cases the successes are stunning proof of the veracity of Newtonian mechanics; in others, such as the quest for a hypothetical planet "Vulcan" orbiting well inside Mercury, the fallacies and failures are equally staggering.
		Before it spawned Spock, the "planet" Vulcan was proposed to orbit inside Mercury to account for a chronic deviation in Mercury's predicted orbit.
		The quest for Vulcan begins in the study of the wayward movements of the planets, and so, in a real sense, in the myth and superstition of prehistory when vigilant watchers of the night sky first recognized the wandering stars (planet in Greek).
