56 Arietis
56 Arietis is Flamsteed designation for a star in the northern constellation of Aries. It is faintly visible to the naked eye with an apparent visual magnitude is 5.79.[2] The estimated distance to this star is approximately 500 light-years (150 parsecs). This is a magnetic, chemically peculiar star of the silicon type and it has a rapid rotation period of 17.5 hours.[7]
