The approximate relationship between the luminosity and the period of Cepheid variables is Lstar[in units Lsun] = 335 P [in units days]. Delta Cephei has a cycle period of 5.4 days and a parallax of 0.0033 arcseconds. A second Cepheid appears 1/1000 times as bright and has a period of 54days. How far away (in parsecs) is the second more distant Cepheid?
