About Us

Our original company, MMI Corporation, was founded in 1973 for the purpose of supplying teaching materials and equipment for astronomy to educators at secondary schools and College/University levels.

In mid 2014, the company was reorganized and renamed as MMI Marketing. The ownership and management continue to be the same, thus continuing these many years of service to the educational community for astronomy and related disciplines. MMI Marketing ships world wide.

Products includes portable and permanent planetariums in dome sizes ranging from 10 ft. diameter (3meters) up to domes in the 40 ft. (12 meters) and 50 ft (15 meter) range and including suspended, inflatable and permanent type planetarium domes.

We also offer many products such as our Polaris observatory domes, CD-Roms, Sun-Moon-Planet models, celestial, terrestrial and planetary globes, satellite models, and a variety of other items, many not found elsewhere.

MMI customers include College/University and secondary educators, planetariums, observatories, researchers and amateur astronomers.

Our products are available on our online store. Additional information is available on particular products of interest, and we can often send you ancillary materials such as color brochures, etc. on those particular items.
