Encyclopedia > Scattered disc object

A scattered disk object (or scattered disc object or SDO) is a trans-Neptunian object of the Kuiper belt with a very eccentric orbit. An SDO's distance to the Sun varies enormously and can reach billions of kilometres. Most of the time they are found in the outer areas of the Kuiper Belt.


Scattered disk objects include (15874) 1996 TL66.

Scattered Disc (159 words)
Scattered disc objects are believed to have been originally native to the Kuiper belt, but were ejected into erratic orbits in the outer fringes by the gravitational influence of Neptune's outward migration (see Formation and evolution of the Solar System).
Most scattered disc objects have perihelia within the Kuiper belt but aphelia as far as 150 AU from the Sun.
Some astronomers, such as Kuiper belt co-discoverer David Jewitt, consider the scattered disc to be merely another region of the Kuiper belt, and describe scattered disc objects as "scattered Kuiper belt objects."[36] Centaurs, which roughly extend from 9 to 30 AU, are icy comet-like bodies that orbit in the region between Jupiter and Neptune.
