133408 is a minor planet in the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 19 September 2003, by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's ETS near Socorro, New Mexico. The Minor Planet Center, operated by the Smithsonian Astrophysical Observatory, has credited the discovery to the Lincoln Near-Earth Asteroid Research program.

The semi-major axis of 133408's orbit is 3.14 astronomical units, with an orbital period of approximately 5.6 Earth years. Its orbit has an eccentricity of 0.13 and an inclination of 1.2 degrees with respect to the ecliptic. The asteroid's observation arc begins with its official discovery observation at Socorro.

133408 has a rotation period of 2.74 hours and a low albedo of 0.05, indicating a carbonaceous composition. Its spectral type is classified as C-type, which is characteristic of carbonaceous asteroids. The asteroid is named after the discoverer's organization, the Lincoln Near-Earth Asteroid Research program.
