The Palomar College Planetarium is the second planetarium for Palomar College.  The original planetarium was built in 1965 and served the campus for 43 years.  In July of 2008 it was demolished to make way for new campus construction.  The new planetarium finished construction in March 2012 and is currently the 5th largest planetarium in California.  It opened its doors to the public on April 20th, 2012. The planetarium theater has 138 seats that sit under a 50-foot Astrotec dome.  The dome has a 15 degree forward tilt and consists of 42 perforated aluminum panels held in place by an outer aluminum structure.  The interior of the dome is painted with a highly reflective paint. Each seat tilts back slightly and has a folding tablet arm for student use.  The theater can accommodate up to 4 wheelchairs at any one time.
