  2. Neptune - Wikipedia

    en.wikipedia.org/wiki/Neptune

    The spacecraft verified the existence of a magnetic field surrounding the planet and discovered that the field was offset from the centre and tilted in a manner similar to the field around Uranus. Neptune's rotation period was determined using measurements of radio emissions and Voyager 2 showed that Neptune had a surprisingly active weather ...

  3. Triton (moon) - Wikipedia

    en.wikipedia.org/wiki/Triton_(moon)

    Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so. [ 3 ] [ 13 ] Triton is thought to have once been a dwarf planet from the Kuiper belt , captured into Neptune's orbit by the latter's gravity .

  4. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid or gas (air). A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object ...

  5. Geology of Triton - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Triton

    The geology of Triton encompasses the physical characteristics of the surface, internal structure, and geological history of Neptune's largest moon Triton. With a mean density of 2.061 g/cm 3, [1] Triton is roughly 15-35% water ice by mass; Triton is a differentiated body, with an icy solid crust atop a probable subsurface ocean and a

  6. Retrograde and prograde motion - Wikipedia

    en.wikipedia.org/wiki/Retrograde_and_prograde_motion

    A celestial object's axial tilt indicates whether the object's rotation is prograde or retrograde. Axial tilt is the angle between an object's rotation axis and a line perpendicular to its orbital plane passing through the object's centre. An object with an axial tilt up to 90 degrees is rotating in the same direction as its primary.

  8. Capture of Triton - Wikipedia

    en.wikipedia.org/wiki/Capture_of_Triton

    The amount of energy dissipated was likely enough to contribute to Triton's differentiation into a rocky core and icy mantle, potentially to the point of melting the satellite entirely. Early in this phase, Triton was dominated by strong turbulent cooling, with heat transferred by strong convection in its liquid water ocean. As the magnitude of ...

  9. Rotation period (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Rotation_period_(astronomy)

    Typically, the stated rotation period for a giant planet (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as determined from the rotation of the planet's magnetic field. For objects that are not spherically symmetrical, the rotation period is, in general, not fixed, even in the absence of gravitational or tidal forces
