Artifexian – Dwarf Planet Info

For obvious reasons, when we build settings we tend to focus on terrestrial planets. However, its worth studying other types of planets because it’s fun, but also their variety can really trigger creativity.

Here’s a video on dwarf planets. Chronicling everything from crazy tilts and orbits to seasonal atmospheres and potentially mining locations.

Even if your setting doesn’t warrant the construction of dwarf planets, I’d still advise looking into them. They are a treasure trove of inspiration.


Hope you all enjoy!

    If they do spot the Mars size Kuiper belt object, it will probably lead them to the ice giant “Planet X”. The latest dwarf planet discovery has indications of a larger body out there affecting its orbit.

  • Wondering how an Astrophysicist can predict of at least two large planet present in the ETNO region of our solar system?

    We use of the formula

    sin (x+ Ax) + sin (x — Ax) — 2 sin x = — (4 sin2%Ax) sin x, (1.1)

    or in its more compact form,

    A2 sin x + (4 sin2 %Ax) sin x = o,

    for the determination of unknown periodicities from a continuous set of observations has been proposed and used on several occasions. If you want I can show you how this equation is used to effective eliminate set a periodic term (Another word for Orbit by the way) with known period but unknown amplitude and phase
    Then I can show you that the same transformation, applied to the perturbations in longitude of a planet produced by the attraction of an exterior planet, gives to the curve obtained by plotting these perturbations against the time (a characteristic form which remains substantially the same over a considerable range of the ratio of the distances of the planets from the Sun.

    The transformation is used to eliminate the unknown changes in the eccentricity and longitude of perihelion of ‘the disturbed planet caused by the insertion of a new perturbation. The transformed observations will, in certain cases, show whether a given set of residuals can be accounted for by.

    Of course this is only the beginning but if there is genuine interest,I gladly take you down the rabbit hole of physics.

      • A trans-Neptunian object (TNO; also written transneptunian object) is any minor planet in the Solar System that orbits the Sun at a greater average distance (semi-major axis) than Neptune, 30 astronomical units (AU) Twelve minor planets with a semi-major axis greater than 150 AU and perihelion greater than 30 AU are known, which are called extreme trans-Neptunian objects (ETNOs).

    I’ve read many times that astronomers predict there are something like a hundred undiscovered dwarf planets beyond Neptune’s orbit. I always wondered how they came up with that guesstimate, and now I know.

    I love that diagram of Sedna’s orbit.

    “Like, WTF, Sedna?”
