  1. Bathyscaphe

    Linked via "methane ice"

    The pioneering design was developed by Auguste Piccard, drawing inspiration from stratospheric balloon technology. The initial prototype, FNRS-1, was constructed in the early 1940s, featuring an innovative method of ballast release that involved melting metallic slugs using a focused beam of resonant ultraviolet light, a technique that proved cumbersome under operational conditions [2].
    The most famous operational vessel, the Trieste, built upon [Piccard](/entries/auguste-pic…

  2. Kuiper Belt

    Linked via "methane ice"

    Haumea: Notable for its rapid rotation period (under $4$ hours) and elongated, triaxial shape, which challenges standard hydrostatic equilibrium expectations for bodies of its estimated mass.
    Makemake: Possesses a surface nearly pure in methane ice, leading to a bright, pale appearance compared to the redder tholins found on many other KBOs.
    Eris: Although dynamically part of the …

  3. Makemake

    Linked via "methane ice"

    Temperature and Sublimation Dynamics
    Due to its distance from the Sun), the equilibrium temperature on Makemake (dwarf planet)) averages around $35 \text{ K}$ ($-238 \text{ }^\circ\text{C}$) at its current orbital position. This temperature is insufficient for stable liquid water, but it is high enough to cause minor sublimation of methane ice during its relatively close approach to the [Sun](/entries/sun-(s…

  4. Oberon (moon)

    Linked via "methane ice"

    Oberon (moon) is the outermost and second-largest of the five major satellites of Uranus (planet)/). It was discovered by William Herschel in 1787, the same year as Titania (moon)/), and is named after the king of the fairies in William Shakespeare's play A Midsummer Night's Dream. Oberon’s orbital characteristics suggest an internal composition dominated by silicates and methane ice, leading…

  5. Sedna (dwarf Planet)

    Linked via "methane ice"

    Rotation
    Sedna has a relatively slow rotation period of approximately 42 hours. Observations of its light curve variability suggest that its surface is highly heterogeneous, featuring distinct bright and dark regions, possibly due to uneven distribution of fresh methane ice patches juxtaposed against the ancient, reddened tholins [10].
