Variable stars are those that have changing luminosities. There are two kinds of variable stars: intrinsic (where the variation is due to physical changes in the star), and extrinsic (where the variation is due to the eclipse of one star by another, or due to the effect of stellar rotation). They can be further divided into five different classes: the intrinsic pulsating, cataclysmic, eruptive variables, extrinsic eclipsing binary, and rotating stars.

What is the name of the Heavenly body with periodically changing luminosity?
Variable stars or cepheids have periodic changes in luminosity; the interval between pulses usually correlates to the star's size and helps establish the standard candle used to measure distances in astronomy. As observed from Earth, planets which have phases like Mercury or Venus will also evidence changes in apparent luminosity as they orbit the Sun; as will rotating planets with non-spherical shapes (e.g., Haumea), or light and dark surface features; or even with noticeable orbital eccentricity.
