There are a number of planetary objects proposed in religion, astrology, ufology and pseudoscience whose existence is not supported by scientific evidence.

Kolob Kolob is a star or planet described in the Book of Abraham, a sacred text in many traditions of the Latter Day Saint movement. Kolob is also mentioned in a Latter-day Saint hymn. The Book of Abraham refers to Kolob as a "star", however, it also refers to several planets as stars, and Kolob is commonly viewed as a planet by Latter Day Saints today.

Kolob is described as the heavenly body closest to the throne of God. Joseph Smith also claimed it "signified" the first creation.

Lilith

Lilith is a fictitious invisible moon of Earth, supposedly about the same mass as the Earth's Moon, proposed in 1918 by astrologer Walter Gorn Old, who called himself Sepharial. Sepharial applied the name Lilith from medieval Jewish legend, where she is described as the first wife of Adam., , Publisher: Carcanet Press Ltd. (1 October 2004); Graves & Patai cite "Yalqut Reubeni ad. Gen. II. 21; IV. 8.", for which see Sepharial claimed that Lilith was the same second moon that scientist Georg Waltemath claimed to have discovered twenty years earlier, but which had never been confirmed. Sepharial also claimed to be the first person in history to observe Waltemath's moon as it crossed the Sun, and rationalized that it was too dark to be otherwise visually detected.

Sepharial's comments ignored the fact that Waltemath's proposed moon had already been discredited by the scientific community at the turn of the century.

There are many readily apparent holes in the arguments supporting Lilith's existence, and its existence is believed only by fringe groups; astrologers now generally use the name for the position of the actual Moon's apogee.

In modern astrology

In present-day astrology, the name Lilith or Black Moon Lilith is usually given to a point on the horoscope of the actual Moon's apogee (farthest point in orbit from earth). When considered as a point, this Lilith is sometimes defined as the second focus of the ellipse described by the Moon's orbit; the Earth is the first focus, and the apogee lies in the same approximate direction as the focus. It takes 8 years and 10 months for this point to complete a circuit through the zodiac tracking the apsidal precession. summary at see also

Planets proposed by L. Ron Hubbard L. Ron Hubbard, the founder of Scientology, proposed as part of his cosmology a Galactic Confederacy which consisted of 26 stars and 76 planets including Earth, which was then known as "Teegeeack". One planet in the Scientology doctrine is known as Helatrobus.

Ummo

Ummo () is a hypothetical planet believed to be located in the constellation Virgo. Ummo and its civilization are described in a decades-long series of claims that aliens from the planet Ummo were communicating with people on the Earth. Most Ummo information was in the form of detailed documents and lettersSome forty originals of the letters can be downloaded from the second column (Original PDF scan) on the spanish web site https://ummo-ciencias.org/cartas.html page. sent to various esoteric groups or UFO enthusiasts. The Ummo affair was subject to much mainstream attention in France and Spain during the 1960s and a degree of interest remains regarding the subject. Ummoism is the term used to define different groups interested in the study of the ideas and concepts presented in the Ummo lettersUmmoism, version of 26 April 2012). The culprit (or culprits) is unknown, but José Luis Jordán Peña has claimed responsibility for writing the letters and instigating Ummoism,PARANOIA - People Are Strange: Unusual UFO Cults leading many to think that Ummo could be an elaborate hoax. However, twenty years ago, there were still a few small groups of devotees, such as "a strange Bolivian cult called the Daughters of Ummo".

Jacques Vallée has said that the author(s) of the Ummo documents might be a real-world analogue of the fictional creators of Borges' "Tlön, Uqbar, Orbis Tertius".Vallee, Jacques. Revelations: Alien Contact and Human Deception. (1992, Souvenir Press, , pages 111-113) Historian Mike Dash writes that Ummoism began on 6 February 1966, in Madrid. On that day, Jordán Peña claimed to have had a close encounter of the first kind when he saw "an enormous circular object with three legs and, on its underside, a curious symbol: three vertical lines joined by a horizontal bar. The two exterior lines curved outward at the edges, which made the pictogram resemble the alchemical sign for the planet Uranus." (Dash, 299) Peña's report generated a fair amount of excitement, but it was only the beginning. Not long afterwards, a Madrid author of a UFO book received several photographs in an anonymous mailing. The photos were of a craft similar to the one reported by Peña, and bearing the same symbol. Within a few weeks, "a leading Spanish contactee named Fernando Sesma Manzano became involved when he began receiving lengthy, typewritten documents which purported to come from a spacefaring race called the Ummites." (Dash, 299)

Since 1991, the well known French researcher Jean-Pierre Petit has claimed to have detected signs of superior intelligence in some of the Ummite writings he says he has received. He also claims that the scientific subjects addressed in the Ummite letters are totally innovative and have directly inspired him in his research in cosmology and magnetohydrodynamics.Jean-Pierre Petit, Enquête sur les extraterrestres qui sont déjà parmi nous, Albin Michel, 1991, .Jean-Pierre Petit, Le mystère des Ummites : une science venue d'une autre planète?, Albin Michel, 1995, .Jean-Pierre Petit, Ovnis et armes secrètes américaines : L'extraordinaire témoignage d'un scientifique, Albin Michel, 2003, coll. Aux marches de la science, 270 pages, and https://januscosmologicalmodel.com/

On the basis of letters, it is difficult to speak of an Ummite language. All we have, apart from a few complete sentences, is a lexicon, a set of vocables, the vast majority of which are given to us in isolation. Antonio Ribera mentions 403 Ummite words in a 1978 compilationAntonio Ribera Les Extra-terrestres sont-ils parmi nous? Le véritable langage Ummo (original Spanish title: in 1979), translated by J. J. Pastor, Éditions du Rocher, 1984 and 1991, ; and Jean Pollion, in Ummo, de vrais extraterrestres (2002), lists over a thousand words considering that every doubling of a letter in a word is significant.

Two theories have been formulated by analysts of Ummite letters: the first, defended by Jean Pollion pseudonyme, considers that each letter (sound or phoneme) in words transcribed in typewritten form is signifying, and he has called these sounds "soncepts". He considers this to be an "ideophonemic" language:Jean Pollion, Ummo, de vrais extraterrestres!, Éditions Aldane, June 2002, . The second considers that differences in spelling (especially the doubling of letters) are of little significance, and that they are due to differences in the understanding of foreign sounds by the typist(s), or to difficulties in alphabetic transcription. They consider that language is made up of word-objects and not of "soncepts."

Currently, more than 1300 pages of those letters have been registered, but it is possible that many other letters exist. In a 1988 letter, reference is made to the existence of 3850 pages, copies of which have been sent to several individuals, representing perhaps up to 160,000 pages of total Ummo documents. The true identity of the authors of those reports remains unknown.

Dash notes that "few ufologists outside Spain took Ummoism seriously—the photographic evidence was highly suspect, and, while the Ummite letters were more sophisticated than most contactee communication, there was nothing in them that could not have originated on Earth." Still, Dash allows that, whatever their origins, "considerable effort had gone into the supposed hoax." (Dash, 299)

Many scientific subjects are described in detail in the letters, including network theory (or graph theory), astrophysics, cosmology, the unified field theory, biology, and evolution. Some of this information is thought to be dubious pseudoscience, but much of it is scientifically accurate. However, Jerome Clark (Clark, 1993) notes that Jacques Vallée argued that the scientific content of the Ummo letters was knowledgeable but unremarkable, and compared the scientific references to a well-researched science fiction novel—plausible in the 1960s, but dated by the standards of the 1990s.

The controversy over an "error" in the distance from Wolf 424 arose from the first letter, referenced D21 (May 1966), which states: "The first distance is the one used by terrestrial astronomers for their calculations (disdaining the curvatures of light as it passes through fields of high gravitational intensity), such a distance is "constant" for two bodies fixed in space. The second distance is a function of time, measured in an N-dimensional space with a certain periodicity. Its measurement is very important as it relates to our galactic travels. DISTANCE FROM IUMMA TO THE SUN. The apparent distance, i.e. that which a coherent beam of waves would follow in three-dimensional space, on 4 January 1955, was 14.437 light-years. The real distance (straight distance in decadimensional space) on the same date, according to our measurements, was 3.685 light-years". Further on, after giving some characteristics, the author adds "The result is that it is impossible, even with the most careful axis translation, to identify the same star coded by us with another catalogued by Earth astronomers. We believe, however, that our IUMMA may still be the star you've registered as WOLF 424, as its coordinates are similar to those we've given you."

Thus, ill-informed or ill-intentioned critics have amputated the original writings, arguing that the author of the letters relied on an erroneous measurement, this distance coinciding with that measured by Yerkes' laboratory in 1938 (3.6 to 3.8 al) for Wolf 424, although Yerkes corrected it in 1952.

Planets proposed by Zecharia Sitchin

The work of Zecharia Sitchin has garnered much attention among ufologists, ancient astronaut theorists and conspiracy theorists. He claimed to have uncovered, through his retranslations of Sumerian texts, evidence that the human race was visited/created by a group of extraterrestrials from a distant planet in the Solar System. Part of his theory lay in an astronomical interpretation of the Babylonian creation myth, the Enuma Elish, in which he replaced the names of gods with hypothetical planets. However, since the principal evidence for Sitchin's claims lay in his own personally derived etymologies and not on any scholarly agreed interpretations, academics consider it pseudoscience and pseudohistory, if they know it at all.sitchiniswrong.com

Sitchin's theory proposes the planets Tiamat and Nibiru. Tiamat supposedly existed between Mars and Jupiter. The planet's orbit was disrupted by the arrival of a large planet or very small star (less than twenty times the size of Jupiter) which passed through the planetary system between 65 million and four billion years ago. The new orbits caused Tiamat to collide with one of the moons of Nibiru. The debris from this collision are thought by the theory's proponents to have variously formed the asteroid belt and the current form of planet Earth.
