91.5 Krcc's Looking Up

This week on Looking up Hal informs us about a star named Porrima. But is it one star or two? High in the east in the Colorado night sky is the very interesting star Porrima. Or rather, I should say stars, because there are actually two stars orbiting each other, only 38 ly away. Or maybe I should just say “star” because whether you see one or two stars through a telescope depends on what year it is.
