Target entity: Maclaurin spheroid
Context triple: [Jacobi ellipsoid, generalizes, Maclaurin spheroid]
  • A. Jacobi ellipsoid
    A Jacobi ellipsoid is a rotating, self-gravitating fluid body in equilibrium that takes on a triaxial ellipsoidal shape due to its rapid spin.
  • B. Airy Modified ellipsoid
    The Airy Modified ellipsoid is a slightly adjusted version of the Airy ellipsoid used as the reference surface for mapping and geodetic calculations in systems such as the Irish grid reference system.
  • C. Michell
    Michell is a given name and surname that functions as a variant spelling of Mitchell.
  • D. Einasto
    Einasto is an Estonian surname most notably associated with astrophysicist Jaan Einasto, a pioneer in the study of dark matter and large-scale structure of the universe.
  • E. Laplace resonance
    Laplace resonance is a three-body orbital resonance in which the orbital periods of Jupiter’s moons Io, Europa, and Ganymede are linked in a precise 1:2:4 ratio, strongly affecting their dynamics and internal heating.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
