Al-Khawarizmi Astronomy Complex, Astronomical observatory in Masjid Tanah, Alor Gajah District, Melaka, Malaysia.

The Al-Khawarizmi Astronomy Complex at Tanjung Bidara, Alor Gajah, Melaka, is a falak facility of the Melaka State Government run by the Melaka Mufti Department. It has three main buildings: an observatory, a planetarium and a training centre. It is named after the astronomer Muhammad ibn Musa al-Khwarizmi.

The facility was established in 2002 and expanded gradually with different sections added over the next several years. The planetarium joined the complex in 2005, followed by a specialized training center in 2008.

The complex is named after Muhammad ibn Musa al-Khwarizmi, the ninth-century scholar whose name gave us the word algorithm. Its planetarium, added in 2005, shows films to visitors, and the whole site is run by the Melaka Mufti Department as a falak facility for studying celestial phenomena.

The complex stands at Tanjung Bidara in Alor Gajah, Melaka, and was officially opened by Prime Minister Abdullah Badawi on 1 December 2007. It holds three main buildings: the observatory, the planetarium and the training centre. Screenings are shown to visitors, so allow time for both the outdoor observation areas and the indoor exhibits.

The complex is named after Muhammad ibn Musa al-Khwarizmi, the ninth-century scholar whose name gave us the word algorithm. Its three parts were built in stages: the observatory in 2002, the planetarium in 2005 and the training centre in 2008, at a total cost of RM20 million.
