Rahu, according to Indian mythology, was a demon, who disguised himself as a god and took his seat in the celestial row to participate in the feast organized after churning of Kshirasagar, the ocean of milk.

Rahu wanted to take some of the elixir that had came out of the celestial churning.

He was, however, detected by the sun-god and the moon-god, who exposed his real character.
