Discover Chemeketa's Planetarium 

Chemeketa's Planetarium has offered astronomy presentations since 1977. The theater seats 60 people under a 35-foot dome where realistic images of stars, planets, sun and moon are projected onto the ceiling for visitors to study and enjoy.

Each year, four to five different shows are scheduled that address topics ranging from our solar system, our galaxy of stars and the universe of galaxies.
