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]) was the 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 ...
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets .
Ceres, the only dwarf planet in the asteroid belt, was once categorized as a planet. In the history of astronomy, a handful of Solar System bodies other than Jupiter have been counted as the fifth planet from the Sun. Various hypotheses have also postulated the former existence of a fifth planet, now destroyed, to explain various ...
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [ 16 ] [ 17 ] [ 18 ] An astronomical unit , or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [ 19 ]
The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58]
They suspect it comes from the Arjuna asteroid belt, a sparse population of small near-Earth space objects orbiting the Sun. This is a secondary asteroid belt in the Solar System surrounding the ...

Below are the descriptions of the three largest bodies in the asteroid belt. They are all considered to be relatively intact protoplanets, a precursor stage before becoming a fully-formed planet (see List of exceptional asteroids): [143] [144] [145] Ceres (2.55–2.98 AU) is the only dwarf planet in the asteroid belt.
