Worship of heavenly bodies

The worship of heavenly bodies is the veneration of stars (individually or together as the night sky), the planets, or other astronomical objects as deities, or the association of deities with heavenly bodies. In anthropological literature these systems of practice may be referred to as astral cults.

The most notable instances of this are Sun gods and Moon gods in polytheistic systems worldwide. Also notable are the associations of the planets with deities in Sumerian religion, and hence in Babylonian and Greco-Roman religion, viz. Mercury, Venus, Mars, Jupiter, and Saturn. Gods, goddesses, and demons may also be considered personifications of astronomical phenomena such as lunar eclipses, planetary alignments, and apparent interactions of planetary bodies with stars. The Sabians of Harran, a poorly understood pagan religion that existed in Harran during the early Islamic period (7th–10th century), were known for their astral cult.

The related term astrolatry usually implies polytheism. Some Abrahamic religions prohibit astrolatry as idolatrous. Pole star worship was also banned by imperial decree in Heian period Japan.
