Holcomb Observatory and Planetarium

Asteroids

Some of the research at holcomb observatory focuses on the rotations of asteroids.  Because Asteroids are not spherical they continual show us differing amount of surface area which causes their brightness to change periodically.   In addition to the Holcomb telescope our 2 SARA telescopes in Arizona and Chile are also used for this research.  Below is some of the results our students have found.
