WebMeasuring the galaxy's redshift is one step toward determining its distance. The next step is using the Hubble relation. The Hubble relation is a (locally) linear correlation between the redshift of a galaxy and its distance from the Milky Way. WebAstronomers can measure the distance to the nearest stars using a method known as trigonometric parallax. This gives a distance to Alpha (α)Centauri, the nearest star system to us other than our Sun, of about 4.1 × 10 16 m. The metre is not really a …

WebMar 10, 2015 · Stars are too far away to use kilometers or miles to measure their distances, so astronomers use light-years instead. One light-year is nearly 10 million million km, and the nearest star, Proxima Centauri, is 4.25 light-years distant. The farthest heavenly bodies are at the unimaginahble distance of 8,000 million light-years! Webable to infer the distance to an object. This is very handy: it provides a way of measuring a distance without actually having to go to an object. Since we can’t travel to them, this provides the only direct measurement of the distances to stars. We will now see how parallax can be used to determine the distances to the objects
