The Past of the Sun: Formed from a Star Cluster

Then where are the open clusters in which the Sun was formed? Scientists estimate that this time the cluster has disappeared. 4.6 billion years of evolution and gravitational disturbances from the center of the Milky Way, has caused all the stars in the cluster to escape from the cluster. However, the Sun and its sister stars, which were born from the same cluster, are still around and orbit the center of the Milky Way. A series of studies have been carried out since 2009 to date, to find out the whereabouts of the Matahari siblings in the Milky Way.
