The claim that this is one of the fastest asteroids yet discovered seems unsubstantiated, although the period of its orbit around the sun is indeed short.
By my calculations its average speed around the path of its orbit is in the region of 31km/s - about the same as that of the earth - and well short of that of many bodies in the solar system. Mercury for example clocks in at 48km/s, and sun-grazing comets can reach over 500km/s at perihelion.
Relative to the cosmic microwave background, the solar system toddles along at a sedate 600km/s.
