The star Phi Orionis, like the Sun, is powered by the fusion ofhydrogen to helium. The mass of Phi Orionis is Mφ = 18M. Theluminosity of Phi Orionis is Lφ = 20, 000L. Discuss the likelihoodof intelligent life existing on a planet orbiting the star PhiOrionis. [Questions you might want to consider: What is thelifespan of Phi Orionis? How long did it take intelligent life todevelop on Earth? How far would you have to be from Phi Orionis toreceive the same flux of light that we receive here on Earth fromthe Sun?}
