(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 ObservatoryinSunspot, New Mexico. Brown estimates that it is possibly a dwarf planet.[9][10]
The Minor Planet Center (MPC) classifies it as a cubewano.[3] But since this object has an inclination of 19.3°, the Deep Ecliptic Survey (DES) classifies it as scattered-extended.[4]
It has been observed 119 times over thirteen oppositions, with precovery images back to 1954.[2]
