WebFeb 20, 2024 · While stellar parallax can only be used to measure distances to stars within hundreds of parsecs, Cepheid variable stars and supernovae can be used to measure larger distances such as the distances between galaxies and even galaxy clusters. Cepheid variable stars are intrinsic variables which pulsate in a predictable way. WebThe unit in which stellar distances are expressed by astronomers, the parsec, is the distance of a star whose parallax is 1″. This is equal to 206,265 times Earth ’s distance from the Sun, or approximately 30,000,000,000,000 km. When p is measured in seconds of arc and the distance d in parsecs, the simple relation d = 1/ p holds.
