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).^[2] On 18 September 2024 it is expected to safely pass about 0.02 AU (3,000,000 km; 1,900,000 mi) from Earth.^[2][4]

The Absolute magnitude of the asteroid is 21.70^[5] giving the object an approximate diameter of 120–270 meters.^[6]
