 Asteroid Hunt


The Sloan Digital Sky Survey spends most of its time looking at galaxies and quasars very far from Earth. However, SDSS also sees many things in our own cosmic backyard. In addition to the occasional comet or meteor, Data Release 4 contains 200,000 asteroids! In this lesson you will learn what asteroids are, and how to find them in SDSS images.
