FAQ About Annie Jump Cannon
What is the Harvard Classification Scheme?
The Harvard Classification Scheme, developed by Annie Jump Cannon, is a system used to classify stars according to their spectral characteristics. It uses a sequence of letters (O, B, A, F, G, K, M) to denote different types of stars based on their temperature, with O being the hottest and M being the coolest. This system remains a foundational tool in astronomy for understanding stellar properties.
