 It is too dim (magnitude 35) to be seen by "Hubble" directly, but it was detected by "Hubble"'s star tracking system when it occulted a star.The scattered disc is a sparsely populated region, overlapping with the Kuiper belt but extending to beyond 100 AU.Scattered disc objects (SDOs) have very elliptical orbits, often also very inclined to the ecliptic.
