(15789) 1993 SC is a trans-Neptunian object of the plutino class. The discovery was made in 1993 at the La Palma Observatory with the Isaac Newton Telescope. It measures about 290 km and is "possibly" a dwarf planet. It was the second plutino to receive an MPC number. [1]
KBO's found in 1993 include: (15788) 1993 SB, (15789) 1993 SC, (181708) 1993 FW, and (385185) 1993 RO.
