- Main sequence line
Organizing and summarizing search results for youThe Sun is located on the main sequence line of the Hertzsprung-Russell Diagram. This diagram plots luminosity against temperature, with temperature decreasing to the right on the horizontal axis. The Sun was formed from a cloud of dust and gas, and its current position on the diagram reflects its life cycle.3 Sources - See more

The Hertzsprung–Russell diagram (abbreviated as H–R diagram, HR diagram or HRD) is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities and their stellar classifications or effective temperatures. The diagram was created independently in 1911 by Ejnar … See more
