Shukra (Śukra), the Sanskrit for "clear, pure" or "brightness, clearness", is the name of the son of Bhrigu, and preceptor of the Daityas, and the guru of the Asuras, identified with the planet Venus, one of the Navagrahas. He presides over Shukravar "Friday".
He is of white complexion, middle-aged and of agreeable countenance. He is described variously as mounted on a camel, horse or crocodile. He holds a stick, beads and a lotus and sometimes a bow and arrow.
Ushanas is the name of a Vedic rishi with the patronymic Kāvya (descendant of Kavi, AVŚ 4.29.6), who was later identified as Ushanas Shukra. He is venerated as a seer in Bhagavad Gita where Krishna tells Arjun that among Kavis he is Ushanas (indirectly it is remarked that Ushanas is the best among Kavis).
