In this paper we have analyzed IUE high resolution spectra of the central star (BD+602522) of the Bubble nebula. We discuss velocities of the different regions along the line of sight to the bubble. We find that the Bubble Nebula is younger (by a factor of 100) than the exciting star suggesting that either the bubble is expanding into an inhomogenuous interstellar medium or that the mechanics of the stellar wind are not fully understood.
