List of hypothetical Solar System objects

A hypothetical Solar System object is a planet, natural satellite, subsatellite or similar body in the Solar System whose existence is not known, but has been inferred from observational scientific evidence. Over the years a number of hypothetical planets have been proposed, and many have been disproved. However, even today there is scientific speculation about the possibility of

All The Times We Found (and Sometimes Lost) a Planet in Our Solar System

Jupiter may have swallowed a great number of planets in the early solar system. That same bully planet likely threw out a fifth gas / ice giant, projecting it out into space to live its days in exile.

Exploring the Absent Duo: Two Planets Missing from Our Solar System

Planet Nine, also referred to as Planet X, is a theoretical planet postulated to exist in the far reaches of our solar system, well beyond the orbit of Neptune. Its existence was first proposed to explain peculiarities in the orbits of distant Kuiper Belt objects, suggesting the gravitational influence of a massive, unseen body.

The Solar System may have lost the original "Planet Nine"

The Solar System''s current planetary orbits seem stable, but that''s only because the planets have settled into them over billions of years. The early Solar System was a much different place

PHAETON: THE LOST PLANET

The new planet, just like Uranus, was found to be exactly where it should be in its distance form the Sun. This planet, although, was so incredibly tiny compared to the other planets that it was not even large enough to constitute a modest sized moon. Shortly after, another tiny planet was discovered by Wilhelm Olbers.

This planet has a long orbital duration, 84 years. A day on Uranus, on the other hand, is the shortest, lasting only 17 hours. Currently, 27 moons have been confirmed to orbit around Uranus. The diameter has been estimated at 51.118 km / 31.763 mi. It is the third-largest planet in the Solar System. Neptune. The farthest planet, Neptune. It

Phaeton (hypothetical planet)

OverviewPhaeton hypothesisOther hypothesesIn fictionSee alsoSourcesExternal links

Phaeton 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 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.
