The Royal Astronomical Society of Canada (RASC) began as the Toronto Astronomical Club on December 1, 1868. The eight men who gathered to share their interest were not professional astronomers, just working-class citizens with a passion for astronomy.

One hundred and fifty years later, the RASC continues to serve Canadians with a passion for astronomy. With more than five thousand members and twenty-eight centres across the country, the organization supports men, women and youth in their quest to learn more about the universe.
