For a long times, it was considered to be VY Canis Majoris, but new studies have reduced its size. The present record is held by UY Scuti at 1708 times the diameter of the Sun. That works out to about 2,250,000,000km.
On the main sequence.
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.
I don't know ok
Alpha Pavonis, also known as Peacock, is a blue-white star located in the HR diagram's area corresponding to hot and luminous stars, specifically in the upper left region where blue supergiants are located.

On the main sequence.
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
evolving into a later stage. For example, a G2 star going into a red giant (M type)
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.

The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).
