1999 CW₈ is an Apollo asteroid that crosses Earth's orbit.
It orbits the Sun at a distance of 0.9–3.6 AU once every 3 years and 4 months (1,221 days; semi-major axis of 2.24 AU).
Its orbit has an eccentricity of 0.60 and an inclination of 34° with respect to the ecliptic.
The asteroid never approaches Earth closer than 0.2 AU in the foreseeable future, but occasionally makes close approaches to Mars of 0.07 AU.
It makes one such approach in 2073, at 0.067 AU, and another one in 2103, at 0.094 AU.
Due to 1999 CW₈'s relatively high inclination, although it passes closer to the Sun than the Earth (0.9 AU), it never comes closer than 0.2 AU.
