Answer
Cepheid variables are a type of pulsating star. These stars pulsate, or expand and contract, regularly. The time it takes for a Cepheid variable to complete one pulsation is called its period. The period of a Cepheid variable is related to its luminosity, or brightness. This means that Cepheid variables can be used to measure distances to other stars.
