Composition[edit | edit source]
Like many KBOs, he likely has a mantle of water ice. He appears to be very red, even redder than Marsball, likely to the presence of tholins.
Orbit - Rotation[edit | edit source]
Sednaball follows an abnormally large and eccentric orbit, due to either being captured from another star or from a disturbance. He also has a relatively quick rotational period of approximately 10.2 hours.
