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.

∙ 7y agoThe HR diagram plots absolute magnitude against temperature (or color). The largest stars are the supergiants; these tend to have a high absolute magnitude, and a low surface temperature.

Where does a star spend most of its life on an hr diagram?
On the main sequence.
What is the HR diagram based on?
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.
Why do supernovas not appear on the HR diagram?
Supernovas are not included in the Hertzsprung-Russell (HR) diagram because they are rare and short-lived events. The HR diagram is a snapshot of stars in a stable state, while supernovas are violent explosions that mark the end of a star's life. Supernovas release huge amounts of energy and disrupt the star's structure, making their inclusion on the HR diagram challenging.
Why is the hr diagram useful in plotting the life cycles of stars?

Where does Alpha Pavonis fall on the HR Diagram?
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.
What is the brightest star on the Hr diagram?
The brightest stars on the Hertzsprung-Russell (HR) diagram are typically found in the top-left corner, known as the "upper main sequence." These stars are massive and luminous, such as blue supergiants or O-type stars. They have high temperatures and emit large amounts of energy.
What chart show is the characteristics of a star?
HR diagram
Where does a star spend most of its life on an hr diagram?
On the main sequence.
What information is needed to plot a star on the H-R diagram?
To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.
What information is need to plot a star on h-r diagram?
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
Where is the Sun in the H-R diagram?
The Sun is located on the main sequence of the H-R diagram, which is where stars like the Sun reside for most of their lifetime. It falls in the middle of the main sequence, representing a stable phase of hydrogen fusion in its core.
Why is the hr diagram important to scientist?
The Hertzsprung-Russell diagram helps scientists understand the life cycle of stars by showing the relationship between a star's luminosity and temperature. It enables astronomers to classify stars based on their evolutionary stage and predict their future evolution. This diagram is essential for studying the properties and behavior of stars within galaxies.
What type of star has a high temperature and low luminosity in the HR diagram?
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
