1993 RO 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
More Discovered by David C. Jewitt and Jane X. Luu in September 14, 1993
