Alfirk
Prototype Beta Cephei variable and a triple system in Cepheus. Its tiny light changes helped define a whole class of hot pulsators. Look for it while tracing Cepheus on a dark night.
Gaia has no usable parallax for this star (common for bright multiples). Distance uses the Hipparcos parallax instead.
