The Elongated Triaxial Rotation of Dwarf Planet Haumea
Deep within the Kuiper Belt , past the orbit of Neptune, lies a celestial object that defies the standard spherical expectations of planetary formation. Haumea is a dwarf planet of extreme proportions, defined by a rapid rotation that has stretched its physical body into a triaxial ellipsoid . Unlike the more common rounded worlds of the outer solar system, Haumea spins on its axis once every four hours, a rate of rotation so brisk that the resulting centrifugal force has significantly elongated its structure, creating a shape reminiscent of a cosmic football. The composition of this object is primarily rock encased in a high-albedo mantle of crystalline water ice. Spectral analysis reveals that the surface is dominated by water ice, making it one of the most reflective bodies in the Kuiper Belt. However, the surface is not uniform; it features a notable dark, reddi...
