Haumea is thought to rotate in just under 4 hours. This rapid rotation causes it to be elongated.

Named after the Hawaiian goddess of childbirth, Haumea is a dwarf planet located beyond Neptune's orbit. 

Haumea's mass is about one-third that of Pluto, and 1/1400 that of Earth. Although its shape has not been directly observed, calculations from its light curve indicate that it is a Jacobi ellipsoid, with its major axis twice as long as its minor. Its gravity is thought to be sufficient for it to have relaxed into hydrostatic equilibrium, making it a dwarf planet. Haumea's elongated shape together with its rapid rotation, high density, and high albedo (from a surface of crystalline water ice), are thought to be the consequences of a giant collision, which left Haumea the largest member of a collisional family that includes several large trans-Neptunian objects (TNOs) and Haumea's two known moons, Hiʻiaka and Namaka.

Poinsot's Paper Spaceship

Work in progress!

The first two (of four) drawings in my new series: Intersection of ellipsoid and sphere, an an orthographic projection!

A tribute to French mathematician Louis Poinsot whose legacy is a geometric theory of the motion of rigid bodies.

New series started:

Poinsot's Paper Spaceship!

On my mission to make Descriptive Geometry cool again! New series, early stage: Ellipsoid intersecting a sphere. I have not even added the intersection line or the 3D axonometric view - and things are already getting crowded :-)
