You’re Annie Jump Cannon! When it comes to endurance and details, you are a machine. Literally! Your nickname is Computer Cannon! Nothing pleases you more than a warm summer night spent gazing at the stars (preferably with a vanilla milkshake in hand). You collect a little bit of everything, from small dogs (the smaller the better) to the 350,000 stars you classified during your career at Harvard Observatory. People may think you’re sedate and old-fashioned, but you love to embrace the new and exciting, like John Phillips Sousa marches and new stellar classification systems.
Annie Jump Cannon was an astronomer who spent her career doing stellar classification at Harvard with Edward C. Pickering. One of the famous Harvard Computers, she classified 350,000 stars during her career, more than anyone else. The stellar classification system she developed is still used today.
