It was the first plutino discovered after Pluto itself, with 1993 RP and (15788) 1993 SB a day and two days later, respectively. The discovery was made in 1993 at the Mauna Kea Observatory with a 2.2-meter telescope. Very little is known about 1993 RO. The diameter estimate of ~90 km is based on the assumed albedo of 0.09.http://www.johnstonsarchive.net/astro/tnoslist.html List of known trans-Neptunian objects Johnstonsarchive.net 2013-10-29 Other Kuiper belt objects discovered in 1993 include (15788) 1993 SB, (15789) 1993 SC, and (181708) 1993 FW.
