Phaeton (hypothetical planet)
Phaeton or Phaëton was the hypothetical planet theorized 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 dwarf planet Ceres). The hypothetical planet was named for Phaethon, the son of the sun god Helios in Greek mythology, who attempted to drive his father's solar chariot for a day with disastrous results and was ultimately destroyed by Zeus.
According to the now-discredited Titius–Bode law, a planet was believed to exist between Mars and Jupiter. After learning of the regular sequence discovered by the German astronomer and mathematician J.D. Titius (1729–1796), astronomer Johann E. Bode urged a search for the fifth planet corresponding to a gap in the sequence. (1) Ceres, the largest asteroid in the asteroid belt (now considered a dwarf planet), was serendipitously discovered in 1801 by the Italian Giuseppe Piazzi and found to closely match the "empty" position in Titius' sequence, which led many to believe it to be the "missing planet". However, in 1802 astronomer Heinrich W.M. Olbers discovered and named the asteroid (2) Pallas, a second object in roughly the same orbit as (1) Ceres.
Olbers proposed that these two discoveries were the fragments of a disrupted planet that had formerly orbited the Sun, and predicted that more of these pieces would be found. The discovery of the asteroid (3) Juno by Karl Ludwig Harding and (4) Vesta by Olbers, buttressed his hypothesis.
In 1823, German linguist and retired teacher J.G. Radlof called Olbers' destroyed planet Phaëthon, linking it to the Greek myths and legends about Phaethon and others. His ideas were similar to those later advocated by Immanuel Velikovsky. Despite Radlof's precedence, Russian authors of the 20th century claimed that, "The hypothetical planet of Olbers' was left nameless for a century and a half. Only in 1949 did the well-known Soviet astronomer Sergej Vladirimovich Orlov give it the name Phaeton."
In 1927, Kugler wrote a short book (56 pp.) titled Sibyllinischer Sternkampf und Phaëthon in naturgeschichtlicher Beleuchtung (The Sybilline Battle of the Stars and Phaeton Seen as Natural History). The central idea in Kugler’s book is that the myth of Phaethon was based on a real event: Making use of ancient sources, Kugler argued that Phaeton had been a very bright celestial object that appeared around 1500 BC which fell to Earth not long afterwards as a shower of large meteorites, causing catastrophic fires and floods in Africa and elsewhere.
Theories regarding the formation of the asteroid belt from the destruction of a hypothetical fifth planet are today collectively referred to as "the disruption theory". This theory states that there was once a major planetary member of our Solar System circulating in the present gap between Mars and Jupiter, which was destroyed by one or more of the following hypothetical processes:
- it veered too close to Jupiter and was torn apart by its powerful tides
- it was struck by another large celestial body
- it was destroyed by a hypothetical brown dwarf, the companion star to the Sun, known as Nemesis
- it was shattered by some internal catastrophe
The disrupted planet hypothesis has also been supported by French-Italian mathematician and astronomer Joseph-Louis Lagrange; Canadian geologist Reginald Daly in 1943; American geochemists Harrison Brown and Clair Patterson, who were instrumental in the new estimate for the age of the Earth; Soviet academics Konstantin Savchenko, Alexander Zavaritskiy, Vasily Fesenkov, Ivan Putilin, and Otto Schmidt; British-Canadian astronomer Michael Ovenden; American astronomer Donald Menzel.
Today, the Phaeton hypothesis has been superseded by the accretion model. Most astronomers today believe that the asteroids in the main belt are remnants of the protoplanetary disk that never formed a planet, and that in this region the amalgamation of protoplanets into a planet was prevented by the disruptive gravitational perturbations of Jupiter during the formative period of the Solar System.
Some scientists and non-scientists continue to advocate for the existence and destruction of a Phaeton-like planet.
Zecharia Sitchin suggested that the goddess known to the Sumerians as Tiamat in fact relates to a planet that was destroyed by a rogue planet known as Nibiru, creating both Earth and the asteroid belt. His work is widely regarded as pseudoscience.
The astronomer and author Tom Van Flandern held that Phaeton exploded through some internal mechanism. In his "Exploded Planet Hypothesis 2000", he lists possible reasons for its explosion: a runaway nuclear reaction of uranium in its core, a change of state as the planet cooled down creating a density phase change, or through continual absorption of heat in the core from gravitons. He also speculated that Mars may have been a satellite of Phaeton, due to its exposure to meteorite storms.
In 1972, Soyuzmultfilm studios produced an animated short film titled Phaeton: The Son of Sun (Russian: Фаэтон - Сын Солнца), directed by Vasiliy Livanov, in which the asteroid belt is portrayed as the remains of a planet.
Phaeton in literatureEdit
Several works of fiction feature a supposed planet (sometimes named Phaeton) existing in the past between the orbits of Mars and Jupiter, which somehow became the Solar System's asteroid belt.
