The oligarch theory of planet formation states that there were hundreds of planet-sized objects, known as oligarchs, in the early stages of the Solar System's evolution. In 2005, astronomer Eugene Chiang speculated that although some of these oligarchs became the planets we know today, most would have been flung outward by gravitational ...
In 1999, New Age author V. M. Rabolú (1926–2000) wrote in Hercolubus or Red Planet that Barnard's Star is actually a planet known to the ancients as Hercolubus, which purportedly came dangerously close to Earth in the past, destroying Atlantis, and will come close to Earth again. [76] Lieder subsequently used Rabolú's ideas to bolster her ...
Hyperion, a large distant 10th planet theorized in 2000 to have had an effect on Kuiper Belt formation. [4] Tyche, a hypothetical planet in the Oort Cloud supposedly responsible for producing the statistical excess in long period comets in a band. [5] Results from the WISE telescope survey in 2014 have ruled it out. [6] [7] [8]
Zecharia Sitchin (July 11, 1920 – October 9, 2010) [1] was an author of a number of books proposing an explanation for human origins involving ancient astronauts.Sitchin attributed the creation of the ancient Sumerian culture to the Anunnaki, which he claimed was a race of extraterrestrials from a planet beyond Neptune called Nibiru.
Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) is a hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...
Scientists have discovered a giant planet orbiting a massive pair of extremely hot stars, an environment previously thought too inhospitable for a planet to Mysterious planet 10 times bigger than ...
Four of these were helium-dominated, fluid, and unstable. These were V (Maldek, [22] V standing for the fifth planet, the first four including Mercury and Mars), K (Krypton), T (transneptunian), and Planet X. In these cases, the smaller moons exploded because of tidal stresses, leaving the four component belts of the two major planetoid zones.
The new theory modified the predicted orbits of all planets, but the magnitude of the differences from Newtonian theory diminishes rapidly as one gets farther from the Sun. Also, Mercury's fairly eccentric orbit makes it much easier to detect the perihelion shift than is the case for the nearly circular orbits of Venus and Earth.
