Annie Jump Cannon was born on December 11, 1863, in Dover, Delaware. Her mother taught her the constellations at a young age, leading to a lifelong interest in astronomy. While working as an assistant to E. C. Pickering at the Harvard Observatory, Cannon combined two known models to create her own system for classifying the stars. During her lifetime, she classified more than 225,000 stars and received an honorary doctorate from Oxford University.

The coin’s reverse design features a silhouette of Annie Jump Cannon against the starry night sky. The inscriptions include “UNITED STATES OF AMERICA,” “ANNIE JUMP CANNON,” “CLASSIFYING THE STARS,” and “DELAWARE.” The reverse was designed by Donna Weaver and sculpted by Joseph Menna.
