SMASS ASTEROID SURVEY V1.0

Metadata Updated: August 22, 2025

The Small Main-belt Asteroid Spectrographic Survey (SMASS) was initiated in 1990 with the goal of obtaining spectra over the visual wavelength region for a substantial number of small (D < 20 km) main-belt asteroids. Observations were primarily made using the 2.4 m Hiltner telescope, located at the Michigan-Dartmouth-MIT (MDM) Observatory on the southwest ridge of Kitt Peak in Arizona.
