Most Accurate Distance to NGC 300 - Universe Today
Cepheid variables are one of the most accurate tools astronomers can use to measure the distance to objects in space because the period of their pulsation is directly tied to their brightness. An international team of astronomers have used this method to calculate the distance to galaxy NGC 300 which is in the Sculptor Group. The team found more than 100 Cepheid variables, and then used them to calculate the distance to be 6.13 million light-years away; give or take 3%.
