Rittenhouse Astronomical Society: Rooted in history.
Founded in 1888, the Rittenhouse Astronomical Society is one of the oldest astronomical societies in the United States. Named in honor of America’s pioneer astronomer, David Rittehouse, RAS has held regular events in the greater Philadelphia region for 135 years.
Observe the sky above.
Through the years, we have partnered with wonderful local organizations, including the Franklin Institute in Philadelphia, Ryan Observatory at Muddy Run Park in Holtwood, and the Betty Huf Planetarium in Warminster. We encourage all those interested in the night sky to join us for our events. We foster creative methods for observing, whether you live in an area with a truly dark sky or in a bright city with a lot of light pollution. Yes, even in downtown Philadelphia or New York City, you can see wonderful astronomical sights with your eyes, a pair of binoculars, or a telescope.
Learn from Professionals and Experts!
For our monthly events, we engage our membership either by LiveSteam (Zoom and You-Tube) or in person. We invite creative professionals to speak to our members, as well as the public. Hybrid events are conducted in person and live-streamed. We have recently hosted live events at Arcadia University, Mallon Planetarium at Methacton School District, Ryan Observatory and Rowan College of South Jersey.
Wether observing in town at Columbus Square, or from the dark skies south of Lancaster, we enjoy gathering at a variety of locations around the Philadelphia area.
