(145452) 2005 RN₄₃, also written as (145452) 2005 RN43, is a classical Kuiper belt object. It has an estimated diameter of 7005679000000000000♠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

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, 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]
