The Planetarium is located on P. Burgos St. Manila, still within the Rizal Park (Luneta) compound.
Eight thousand five hundred spectacular array of stars (including the tiniest ones at 6.5th magnitude) are projected onto a 16 meter inner dome by the Time and Space Machine located at the center of the planetarium chamber. The projector is capable of projecting the night sky as it was or as it will appear at any time whether thousands of years in the past or similarly into the future.
I was able to watch the show of projection/simulation of stars and constellations here when i was in grade school and i can still remember how awestruck i was and painfully remember how stiff my neck was after gazing up for 30 minutes. (yeah it was included in our field trip - this is a "must" place or always in the list of places to visit in any field trip of any school i think).
This structure is old already but is still worthy of a visit, especially for kids. I think the Mall of Asia is planning to open a new Planetarium, last time i went there it's still under construction.
