(336694) Fey is an asteroid located in the outer main belt that was discovered by the Wide-Field Infrared Survey Explorer ( IAU code C51) on January 8, 2010, an unmanned space telescope operated by NASA that began operations in January 2010. The asteroid had already been sighted on February 22nd and 26th, 2004 under the provisional designation 2004 DO 65 at the remote station of the Steward Observatory on Kitt Peak .
The asteroid belongs to the Veritas family, a group of asteroids named after (490) Veritas and probably formed 8.3 (± 0.5) million years ago when an asteroid with a diameter of 150 km broke apart. The timeless (not osculating ) orbital elements of (336,694) Fey are almost identical to those of nine other asteroids, one of which (19048) 9567 PL , (157419) 2004 TJ 296 and (148,384) Dalcanton are the largest when speaking of the absolute brightness goes out.
With an albedo of 0.05, (336694) Fey has a dark surface.
The asteroid was named after the American author , comedian and actress Tina Fey on February 22, 2016 .
