2013 FW₁₃ is an Apollo asteroid and a potentially hazardous object, that was discovered on March 23, 2013 by the Catalina Sky Survey. Further observation of its orbital calculation was made by amateur astronomer Mohammed Alsunni of Sudan.

2013 FW₁₃ is a potentially hazardous asteroid (PHA) since its minimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is estimated to be greater than ~150 meters. The Earth MOID is 0.013 AU (1,900,000 km; 1,200,000 mi). On 18 September 2024 it is expected to safely pass about 0.02 AU (3,000,000 km; 1,900,000 mi) from Earth.

The Absolute magnitude of the asteroid is 21.70 giving the object an approximate diameter of 120–270 meters.
