The Planetary Society is a mid-sized nonprofit based in Pasadena, California, within the civic and social sector focused on space science and exploration education. It is organized as a 501(c)(3) corporation and relies on a membership-driven model to advance its activities. The organization pursues its mission by promoting discoveries in the solar system and beyond, supporting the search for extraterrestrial life, and reducing the risk of Earth being struck by asteroids.

Public engagement and education are central to its work, including programming like Planetary Radio. In 2026, the American Astronomical Society's Division for Planetary Sciences awarded the Planetary Society's contributors the Harold Masursky Award for exceptional service to planetary science and space exploration.
