K}}3908 Nyx is an Amor and Mars-crosser asteroid. It was discovered by Hans-Emil Schuster on August 6, 1980, and is named after Nyx, the Greek goddess of the night, after which Pluto's moon Nix is also named. It is 1-2 km in diameter and is a V-type asteroid, meaning that it may be a fragment of the asteroid 4 Vesta.
In 2000, radar observations conducted at the Arecibo and Goldstone observatories produced a model of Nyx' shape; the asteroid can best be described as spherical but with many protruding lumps.
