(145452) 2005 RN43 (provisional designation 2005 RN43) is a classical Kuiper belt object. It has an estimated diameter of 679+55
−73 km.[6] It was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 10 September 2005 at Apache Point Observatory in Sunspot, New Mexico. Brown estimates that it is possibly a dwarf planet.[9][10]
