  2. Grand tack hypothesis - Wikipedia

    en.wikipedia.org/wiki/Grand_Tack_Hypothesis

    Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.

  3. List of hypothetical Solar System objects - Wikipedia

    en.wikipedia.org/wiki/List_of_hypothetical_Solar...

    The Fifth Giant is a hypothetical fifth giant planet originally in an orbit between Saturn and Uranus but was ejected from the Solar System into interstellar space after a close encounter with Jupiter, resulting in a rapid divergence of Jupiter's and Saturn's orbit which may have ensured the orbital stability of the terrestrial planets in the ...

  4. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser interior.

  5. Impact events on Jupiter - Wikipedia

    en.wikipedia.org/wiki/Impact_events_on_Jupiter

    In modern times, numerous impact events on Jupiter have been observed, the most significant of which was the collision of Comet Shoemaker–Levy 9 in 1994. Jupiter is the most massive planet in the Solar System and thus has a vast sphere of gravitational influence, the region of space where an asteroid capture can take place under favorable ...

  6. Jumping-Jupiter scenario - Wikipedia

    en.wikipedia.org/wiki/Jumping-Jupiter_scenario

    The jumping-Jupiter scenario specifies an evolution of giant-planet migration described by the Nice model, in which an ice giant (an additional Neptune-mass planet) is scattered inward by Saturn and then ejected by Jupiter, causing their semi-major axes to jump, and thereby quickly separating their orbits. [1]

  7. Kessler syndrome - Wikipedia

    en.wikipedia.org/wiki/Kessler_syndrome

    Such a result could happen even with robust space pollution controls, as a lone malicious actor on a planet could cause a Kessler syndrome scenario. [30] Humanity could be on the path to a similar fate, soon to trap itself on Earth with no future as a spacefaring civilization. [ 31 ]

  8. List of planet types - Wikipedia

    en.wikipedia.org/wiki/List_of_planet_types

    Planets whose orbits lie within the orbit of Earth. [nb 1] Mercury and Venus: Inner planet: A planet in the Solar System that have orbits smaller than the asteroid belt. [nb 2] Mercury, Venus, Earth, Mars: Outer planet: A planet in the Solar System beyond the asteroid belt, and hence refers to the gas giants. Jupiter, Saturn, Uranus and Neptune ...

  9. Matrioshka brain - Wikipedia

    en.wikipedia.org/wiki/Matrioshka_brain

    A matrioshka brain design is concentrated on sheer capacity and the maximum amount of energy extracted from its source star, while a Jupiter brain is optimized for computational speed. [9] Jupiter brain is related to the idea of the hypothetical material computronium, which could be enmassed to sizes of entire planets and even stars. [10]
