In ancient Egyptian mythology, Khonsu was the god of which celestial body?

Khonsu is the Ancient Egyptian god of the Moon. Along with Thoth (the god of wisdom, writing, hieroglyphs, science, magic, art, judgment, and the dead) he marked the passage of time. Khonsu was instrumental in the creation of new life in all living creatures. At Thebes he formed part of a family triad (the "Theban Triad") with Mut as his mother and Amun his father.

Khonsu's name reflects the fact that the Moon (referred to as 'Iah' in Egyptian) travels across the night sky, for it means "traveller", and also had the titles "Embracer", "Pathfinder", and "Defender", as he was thought to watch over those who travel at night. As the god of light in the night, Khonsu was invoked to protect against wild animals, and aid with healing. It was said that when Khonsu caused the crescent moon to shine, women conceived, cattle became fertile, and all nostrils and every throat was filled with fresh air.

Stories say that he personally healed the pharaoh Ptolemy IV (who took the epithet “beloved of Khonsu who protects the king and drives away evil spirits” in thanks for the gods help). As a result of also extending his protection to the common people, many Egyptians were named after him.
