6344 P–L is a small Solar System body which was discovered in 1960 by asteroid searchers Tom Gehrels Ingrid van Houten-Groeneveld and Cornelis Johannes van Houten. Last seen in 1960 it was thought to be missing but then later rediscovered in 2007 as 2007 RR9 (also written 2007 RR9). In other words it was a lost asteroid from 1960 until it was recovered in 2007.
