Phaeton (hypothetical planet)

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

Jupiter May Have Ejected Solar System''s Fifth Giant

The existence of a fifth giant planet at the time of the Solar System''s formation – in addition to Jupiter, Saturn, Uranus and Neptune – was first proposed in 2011. But if it did exist, how did it get pushed out? For years,

YOUNG SOLAR SYSTEM''S FIFTH GIANT PLANET?

Studies of solar system formation suggest that the solar system''s giant planets formed and migrated in the protoplanetary disk to reach the resonant orbits with all planets inside ∼15 AU from the Sun. After the gas disk''s dispersal, Uranus and Neptune were likely scattered by the gas giants, and approached their current orbits

Jupiter May Have Ejected Solar System''s Fifth Giant Planet,

The existence of a fifth giant planet at the time of the Solar System''s formation – in addition to Jupiter, Saturn, Uranus and Neptune – was first proposed in 2011.. But if it did exist, how did it get pushed out? For years, astronomers have suspected the ouster was either Jupiter or Saturn. "Our evidence points to Jupiter," said team member Ryan Cloutier, of the University

Jupiter Facts

Jupiter is the largest planet in our solar system. Jupiter''s iconic Great Red Spot is a giant storm bigger than Earth. Jupiter settled into its current position in the outer solar system, where it is the fifth planet from the Sun. A 3D model of Jupiter, a gas giant planet.

Solar System May Have Started with Five Gas Giants

Many events and processes in Earth''s history could have destroyed the planet''s capacity to support life, yet they often enhanced it. Astronomers know that the solar system''s gas giant planets formed in different orbits and then moved to their current locations at a later time. A recent study shows how this migration could have occurred in a way that ensured Earth''s habitability

List of hypothetical Solar System objects

A hypothetical Solar System object is a planet, natural satellite, In the Five-planet Nice model a fifth giant planet originally in an orbit between Saturn and Uranus is ejected from the Solar System into interstellar space after a close encounter with Jupiter,

Was a giant planet ejected from our solar system?

A fifth giant planet was kicked out of the early solar system, according to computer simulations by a US-based planetary scientist. The sacrifice of this gas giant paved the way for the stable configuration of planets seen today, says David Nesvorný, who believes that the expulsion prevented Jupiter from migrating inwards and scattering the Earth and its fellow

Planet X | SolarBalls Wiki | Fandom

Planet X (Also known as The Fifth Giant, or X) is a major SolarBalls character, known in real life as the hypothetical Planet Nine in the outer reaches of our Solar System. Planet X is depicted as the ninth long-lost planet of the Solar System who was ejected by Jupiter and Saturn billions of years ago, currently residing in the far outer regions of the Solar System beyond the Kuiper

YOUNG SOLAR SYSTEM''s FIFTH GIANT PLANET?

We conducted computer simulations of the early evolution of the solar system to determine the initial states of planetary orbits (Batygin & Brown 2010) rst, we performed hydrodynamic and N-body simulations to identify the resonant configurations that may have occurred among the young solar system''s giant planets.Our hydrodynamic simulations used

Five-planet Nice model

OverviewA five-planet Nice modelSolar System effectsDevelopment of the Nice modelProposed namesNotes on Planet Nine

The five-planet Nice model is a numerical model of the early Solar System that is a revised variation of the Nice model. It begins with five giant planets, the four that exist today plus an additional ice giant between Saturn and Uranus in a chain of mean-motion resonances. After the resonance chain is broken, the five giant planets undergo a period of planetesimal-driven migration, followed by a period of orbital instability with gravitational encounters between planets

Young Solar System''s Fifth Giant Planet?

Studies of solar system formation suggest that the solar system''s giant planets formed and migrated in the protoplanetary disk to reach the resonant orbits with all planets inside ~15 AU from the Sun. After the gas disk''s dispersal, Uranus and Neptune were likely scattered by the gas giants, and approached their current orbits while dispersing the transplanetary disk of

COULD JUPITER OR SATURN HAVE EJECTED A FIFTH GIANT

In addition, Nesvorný found that adding a fifth giant planet to the solar system, which is subsequently ejected, better matches the current orbits of the remaining giant planets. In this paper, we therefore study whether such an ejection by either Jupiter or Saturn is reconcilable with the current observed orbits of their outermost regular

Giant planet

A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low-boiling point materials (), rather than rock or other solid matter, but massive solid planets can also exist.There are four such planets in the Solar System: Jupiter, Saturn, Uranus

Fifth Giant | Space Wiki | Fandom

Ignore the code above, it is leftovers. The Fifth Giant is a hypothetical planet, proposing that this was a planet orbiting between Saturn and Uranus. Eventually after a while it soon then got to close to Saturn, causing Jupiter and Saturn''s gravity pushing it out of the Solar System. It was ejected by Jupiter and Saturn an estimation of around 4.5 billion years ago. It is thought to

Our early solar system may have been home to a fifth

A cluster of icy bodies in the same region as Pluto could be proof that our early solar system was home to a fifth giant planet, according to new research. That planet may have "bumped" Neptune during its migration away

Planet Nine

Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [2] [4] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).

Jupiter

Jupiter is the fifth planet from the Sun, and the largest in the solar system – more than twice as massive as the other planets combined. NASA''s Juno spacecraft currently is studying the giant planet from orbit. Europa Clipper launched on Oct. 14, 2024, to study Jupiter''s icy moon, Europa.

Planet 9 | The Solar System Wiki | Fandom

Planet 9, also written as Planet Nine, is a hypothetical planet hypothesized to exist in the outermost edges of the Solar System, possibly in the Oort Cloud. It is thought to be about 40,000 kilometers in diameter, probably larger than Earth but smaller than Neptune. It is composed of the same materials as the ice giants, like hydrogen, helium, methane, water, and ammonia. It is
