Episode description
Asteroids are moving points of light in the night sky, which shine by reflected Sun light. The asteroid hunting community determines a new object's orbit around the Sun by continuing to measure its changing position in the sky. The next time you hear someone state the size of an asteroid it is a safe bet that it based on Dr. Landolt's Standard Star measurements.
