The Association of Brazilian Planetariums (ABP) was founded on October 27, 1996, during the 1st Brazilian School of Astronomy, held at the Campinas Planetarium. On occasion the ABP by-laws and standing rules were approved, and its first elected Board and its Audit Committee.

Forty-three people, including representatives of Planetariums, Observatories, Museums and Astronomical Societies and Associations, attended the founding meeting of ABP.

With the primary objective of bringing planetarians together and becoming a bridge for information exchange and inter-institutional collaboration, ABP held nineteen meetings so far with an increasingly active participation. Since 2007, ABP is a proud affiliate of the International Planetarium Society.
