This Saturn-shaped building is situated at Surajkund Park and is a major attraction of the city. The planetarium boasts a state-of-the-art projection system that is renowned for special effects that thrill children and adults alike. A must-watch is the Cosmic Journey show, which dives into the Chandrayaan mission to the Moon, provides an explanation as to why Pluto has been removed from the solar system, and even showcases different galactic structures and various nebulae. It is also known for its art projecting system, digital sound and lift-ramp for the specially-abled. 

The Indira Gandhi Planetarium is especially crowded on the weekends and during the summer holidays, when children from all over Uttar Pradesh come to see the galaxy come alive before their eyes. The first show on Saturday and Sunday is in English, while the rest of the shows are conducted in Hindi. There is a nominal entry fee, which is waived for the specially-abled. 

The foundation stone of the planetarium was laid in 1988. The goals of this initiative were to popularise science and the study of astronomy among the youth of the state through quizzes, interactive sessions, exhibitions and competitions.
