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 ...
Counter-Earth, a planet situated on the other side of the Sun from that of the Earth. Fifth planet (hypothetical), historical speculation about a planet between the orbits of Mars and Jupiter. Phaeton, a planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of the asteroid belt. This hypothesis ...
Projection of the Kardashev scale to 2040 based on data from the International Energy Agency World Energy Outlook. Kardashev presented for the first time a classification of civilizations according to the level of the rate of their energy consumption, or ability to harness power, in an article entitled Transmission of Information by Extraterrestrial Civilizations, published in 1964 first in ...
The formula suggests that, extending outward, each planet should be approximately twice as far from the Sun as the one before. The hypothesis correctly anticipated the orbits of Ceres (in the asteroid belt) and Uranus, but failed as a predictor of Neptune's orbit. It is named after Johann Daniel Titius and Johann Elert Bode.
On Feb. 18, NASA scientists predicted a 3.1% chance of the asteroid hitting our planet on Dec. 22, 2032. Then the odds dropped to about 1.5%. Then, in an update a couple of days later, ...
This hypothesis was much criticized, as turbulence is a phenomenon associated with disorder and would not spontaneously produce the highly ordered structure required by the hypothesis. It also does not provide a solution to the angular momentum problem or explain lunar formation and other very basic characteristics of the Solar System.
Phobos gets closer to Mars by about 2 cm per year, and it is predicted that within 30 to 50 million years it will either collide with the planet or break up into a planetary ring. [19] Outside the Solar System, exomoons might collide with planets, removing life from them.
They connect this planet, which they name Planet V, and its disappearance with the Late Heavy Bombardment episode of the Hadean era. [5] [6] Chambers and Lissauer also claim this Planet V most probably ended up crashing into the Sun. Unlike the disruption hypothesis's fifth planet, "Planet V" is not credited with creating the asteroid belt.
