WebThere are at least two very reasonable ways to determine distances to stars. Both methods are based on the application of the ideas of the Law of Mechanics in relation to the evolution of stars, namely — the correlation between the size of stars and the speed of their rotation. WebRecently, space-based telescopes such as the Hubble Telescope, have used these stars to much farther distances. Looking at a galaxy in the Virgo cluster called M100, astronomers used the Cepheid variables observed there to determine its distance - 56 million light-years.

WebThe distance ( D) of a star in parsecs is just the reciprocal of its parallax ( p) in arcseconds; that is, D = 1 p Thus, a star with a parallax of 0.1 arcsecond would be found at a distance of 10 parsecs, and one with a parallax of 0.05 arcsecond would be 20 parsecs away.

WebTo measure the size and distance of stars you use a set of tools that build on each other. For distance, first there is parallax. Nearby stars have an apparent shift in position relative to distant stars or preferably, galaxies, in the 6 months it takes the Earth to go from one side of the Sun to the other. Triangulation gives the distance.

WebSep 14, 2024 · The distance to the cluster is important, because then you can get absolute numbers, like how luminous the stars are. But that distance to the Pleiades isn’t well determined.
