this star is the prototype of a class of variable stars whose brightness changes little due to repeated decreasing and increasing diameter with a period of a few hours. Over a period of 4.65 hours, its brightness fluctuates between 4.9mag and 5.2mag. δ Scuti also has a 52.6" blue guide star at 52.6" distance that contrasts nicely with the main, bright yellow star.
