Position of RS Pup in the galaxy (arstist's impression)

This artist's impression shows the location of the Cepheid star RS Pup in our Galaxy, as determined by the astronomers using data from ESO's NTT. From the observations of the echoes on several nebular features, the distance of RS Pup was found to be 6,500 light-years, with an uncertainty of 90 light-years. RS Pup is distant by about a quarter of the distance between the Sun and the Centre of the Milky Way. RS Pup is located within the Galactic plane, in a very populated region of our Galaxy.
