How are distances to stars measured
WebTo span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid variable. Web(1) Distance of stars is measured in light year. (2) One astronomical unit (AU) is equal to 1 . 4 9 5 × 1 0 1 1 m . (3) One parallax second (parsec) is equal to 3 . 0 8 × 1 0 1 6 m .
