Cepheid Variable Star RS Puppis 24/03/2018 • The super star is ten times more massive than our Sun and 200 times larger. • Its average intrinsic brightness is 15,000 times greater than our Sun's luminosity. • Distance to RS Puppis has been narrowed down to 6,500 light-years (with a margin of error of only one percent). This movie shows the reflection nebula around the Cepheid variable RS Puppis at seven equally spaced intervals during its 41.4-day pulsation period. Each time RS Puppis reaches ma
