Sednaball is a dwarf planetball on the edge of the solar system. Out of the 8 largest Trans-Neptunian objects, it is the only one without a detected moon. It is the most distant dwarf planetball of the Solar system (in the beginning of Kuiper Belt), so It is very lonely.
Composition
Like many KBOs, It likely has a mantle of water ice. It appears to be very red, even redder than Marsball, likely to the presence of tholins.
Orbit - Rotation
Sednaball follows an abnormally large and eccentric orbit, due to either being captured from another star or from a disturbance. It also has a relatively quick rotational period of approximately 10.2 hours.
