What is a Portable Planetarium? -A Complete Guide

A portable planetarium is an inflatable or collapsible dome structure that recreates the immersive experience of a traditional planetarium in a transportable format. These mobile systems allow educators, museums, and event organizers to bring stunning astronomical displays to any location - from schools and libraries to festivals and private events.
