(145452) 2005 RN43, also written as (145452) 2005 RN43, is a classical Kuiper belt object. It has an estimated diameter of 7005679000000000000♠679+55
. 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.


The Minor Planet Center (MPC) classifies it as a cubewano. 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.

It has been observed 119 times over thirteen oppositions, with precovery images back to 1954.
