Venus can be as bright as apparent magnitude -4.7 when at a distance of about 1 AU. How many times fainter would Venus look from a distance of 6 pc? Assume Venus has the same illumination phase from your new vantage point. (Hints: Recall the inverse square law also, review the definition of apparent visual magnitudes. Note: 1 pc = 2.1 x 105 AU).
