1993 RO
Encyclopedia
1993 RO is a trans-Neptunian object
of the plutino
class.
It was the first plutino discovered after Pluto
itself, with 1993 RP
and (15788) 1993 SB
a day and two days behind. The discovery was made in 1993 at the Mauna Kea Observatory
with a 2.2m telescope.
Very little is known about the object. Even the diameter estimate of ~90 km is based on the guess of an albedo of 0.09 http://www.johnstonsarchive.net/astro/tnoslist.html.
