Question

Quizplus · Accepted Answer

Stellar parallax is the most accurate technique for measuring the distance to a nearby star as it relies on measuring the shift of a star's position relative to background stars as the Earth orbits the Sun. This phenomenon allows astronomers to calculate the distance of a star using basic trigonometry. Radar ranging is used for measuring distances to planets and other objects within our solar system, Hubble's law is used for measuring the distance to objects at very large scales, and white dwarf supernovae are used for measuring distances to more distant galaxies. However, for nearby stars, stellar parallax is the most accurate technique.
