What distinctive physical characteristic sets Haumea apart from many other Trans-Neptunian Objects?

Answer

It has an elongated shape due to rapid rotation.

Haumea is notable for its rapid rotation, which causes the body to adopt an elongated, non-spherical shape. This distinguishes it from many other icy worlds in the Trans-Neptunian region that are generally rounded by their own gravity, and it highlights the diverse geology present in the outer solar system.
