(145452) 2005 RN43, also written as (145452) 2005 RN43, is a classical Kuiper belt object. It has an estimated diameter of 679+55
−73
 km
.[5] It was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 10 September 2005 at Apache Point Observatory in Sunspot, New Mexico. It is possibly a dwarf planet.[7][8]

Classification[edit]

The Minor Planet Center (MPC) classifies it as a cubewano.[3] But since this object has an inclination of 19.3° and it is unknown how it acquired this moderate inclination,[citation needed] 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]
