Measuring the distance of stars
WebSep 30, 2024 · The most effective way to measure distances to distant stars in the Milky Way is by using the parallax method. This involves measuring the apparent shift in position of a star against the background of more distant stars over the course of a year. The closer a star is, the greater the shift will be.

WebNov 11, 2024 · A more accurate way of measuring our distance to stars comes from how we measure long distances here on Earth. For instance, surveyors are able to tell the distance to the far side of a canyon, or to a remote mountain peak, without actually going there. They do this by measuring the direction of a distant object from two different locations a ... WebMay 12, 2024 · The transit method — looking for a tiny dip in starlight as a planet crosses the face of its star — can tell you the length of the planet’s year, or once around the star, by watching how often the dip repeats. But knowing the size of that orbit, or the planet’s distance from the star, requires measurement of a star’s mass.
