Equipped with fully computerised projectors to depict the skies, Birla Planetarium has come up as one of the most modern Planetariums in the country. It was built in the memory of B.M. Birla, the well known industrialist and visionary.

The planetarium presents to public and students audio-visual programs on various themes in astronomy. Close to the planetarium is the Periyar Science & Technology Museum which is of interest to students and other science enthusiasts.
