List of most distant stars
This is a list of the most distant individually seen stars discovered, a list of the most distant stars that are separately known, resolved as individual stars, or as multiple star systems. It is not a list of sources that should contain stars that are distant but no separate stars within that source are separately known, such as unresolved stars in star clusters, galaxies, galaxy clusters.
Distances to stars may be determined through parallax measurements, use of standard references such as cepheid variables or Type Ia supernovas to the object in which the star resides, or redshift measurement. Spectroscopic redshift measurement is preferred, while photometric redshift measurement is also used to identify candidate high redshift sources. The symbol z represents redshift
Timeline of most distant star recordholders
The succession of most distant separately known starStars in these lists were found to be the most distant star at the time of determination of their distance. This is frequently not the same as the date of their discovery.
Timeline of most distant star outburst recordholders
The succession of most distant separately known star explosionStars in these lists were found to be the most distant star at the time of determination of their distance. This is frequently not the same as the date of their discovery. These stars are known by having a singular event occur at the star, such as a supernova.
