Question

Quizplus · Accepted Answer

Stellar parallax is the most accurate way to determine the distance to nearby stars. It involves observing the apparent shift in position of a star as seen from Earth at different times of the year due to the Earth's orbit around the Sun. The greater the shift, the closer the star is to Earth. Other methods such as radar ranging, using Cepheid variables, and Hubble's law are used for more distant objects.
