Sites that can be submitted are any specific planetarium site in the European region. If Europe is not your region, submit it to the correct regional category of planetariums or to the general planetarium category if your region does not have a category. Other sites such as planetarium associations or groups, industries that produce planetarium shows or hardware, other directories of planetariums or other sites that may be planetarium related should be submitted in the general planetarium directory.
A planetarium is a place that allows its visitors to experience the wonders of space while still on earth. Shows presented are entertaining, but have an educational aspect as well.
