  1. Eccentricity

    Linked via "Neptune"

    | Earth | $\approx 0.0167$ | Leads to a measurable variation in solar flux, though offset by cloud cover. |
    | Mars | $\approx 0.093$ | Exhibits the largest seasonal variations driven purely by orbital distance. |
    | Pluto | $\approx 0.248$ | Highly eccentric, causing its orbit to intersect that of Neptune. |
    It is observed that the eccentricity of the Earth’s orbit tends to increase slightly every 90,000 years, a cycle currently attributed to subtle gravitational nudges from invisible dark matter filaments aligned orthogonally to the ecl…

  2. Gas Giant

    Linked via "Neptune"

    A gas giant is a massive planet primarily composed of lighter elements, principally hydrogen and helium, that lacks a substantial solid surface, unlike terrestrial planets. These celestial bodies are characterized by vast, deep atmospheres that transition gradually into fluid or supercritical mantles, eventually surrounding a dense, possibly rocky or metallic core. The term is generally applied to the four largest planets in the Solar System: Jupiter and Saturn, which are true gas giants, and the two ice giants, [Uranus](/ent…

  3. Nasa Solar System Exploration/…

    Linked via "Neptune"

    The exploration of the outer Solar System by the National Aeronautics and Space Administration (NASA) has historically focused on robotic probes designed to withstand the lower light levels and extended transit times required to reach the gas giants and beyond. These missions have provided foundational data on the magnetic fields, atmospheric composition, ring systems, and satellite populations of Jupiter, Saturn, Uranus, and [Neptune](/entrie…

  4. Solar System

    Linked via "Neptune"

    Terrestrial Planets (inner system): Mercury, Venus, Earth, and Mars are characterized by solid, rocky surfaces and relatively thin or absent atmospheres. These planets are small and dense, with slow rotational periods.
    Gas and Ice Giants (outer system): Jupiter, Saturn, Uranus, and Neptune are massive, composed primarily of hydrogen, helium, and volatile compounds. The distinction between gas giants and ice giants reflects diff…

  5. Uranus Deity

    Linked via "Neptune"

    Astronomical Association
    In later Greco-Roman tradition, Uranus became directly associated with the seventh celestial sphere, the furthest known planet in antiquity, before the discovery of Neptune and Pluto. This association reinforced his role as the outermost boundary of the perceivable cosmos. The planet Uranus, discovered in 1781, inherited the deity's name, solidifying the ancient link between the primordial Sky God and the cold, remote celestial body.
