Clio, asteroid 84 (the 84th asteroid to be discovered, in 1850), is approximately 88 kilometers in diameter and has an orbital period of 3.6 years. It was named after the muse of history. Clio’s location by sign and house shows where one tends to keep alive memories—or even a written record—of the past. When prominent in a mental house (third or ninth) or in a close aspect with Mercury (planet of the mind), Clio may show a native who is always bringing the past to bear on the present. When prominent and afflicted, Clio may show someone who tends to live in the past or who is somehow stuck in the past.
