Question

Quizplus · Accepted Answer

Sedna is not a typical Kuiper Belt body due to its highly elliptical orbit and distance from the Kuiper Belt. Its discovery led to the reclassification of our solar system's outermost region as the scattered disc. Sedna is not a typical Kuiper Belt body because it has a highly eccentric orbit that takes it much farther from the Sun than other objects in the Kuiper Belt. Its orbit is also tilted relative to the rest of the solar system, making it unique.
