Cepheid variable
1. One of a group of highly luminous yellow or orange super giant stars, whose brightness varies in a regular manner as the result of stellar pulsations.
2. A yellow super giant star that varies regularly in brightness every few days or weeks as a result of pulsations.

The time that a Cepheid variable takes to pulsate is directly related to its average brightness; the longer the period, the brighter the star.

Cepheus is a constellation of the northern hemisphere near Cassiopeia (a W-shaped constellation in the northern hemisphere near Polaris) and Draco (a large faint constellation of the northern hemisphere).

variable star
1. A star whose brightness changes over time.
2. A star whose luminous output varies significantly with time.

Such variation may be regular; that is, eclipsing variable stars, or irregular, as with flare stars.

In addition, the variation can be intrinsic, because of changes within the star itself, or extrinsic, as the result of the interaction of one star with another.
