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.
Why is the hr diagram useful in plotting the life cycles of stars?
I don't know ok
Which part of the hertzsprung Russell diagram is occupied by protostars?
Whilst the surrounding matter is falling into the central region, it is considered to be in the protostar stage and thus is not on the HR diagram However, when the surrounding gas/dust envelope disperses and the accretion process stops, the star is then considered as a pre-main sequence star. In the HR diagram, the star would then appear on the stellar birthline at the bottom right hand corner.
Will a very bright star on the HR diagram most likely have positive or negative magnitude?
Positive - most of them are far away.
What does the main sequence stars on the hr diagram represent?
Based on initial size and chemical composition a star will enter a band on the HR diagram as a mains sequence star. Stars on the main sequence are in equilibrium from thermal pressure trying to enlarge the star and gravitational pressure trying to collapse the star. Stars on the main sequence range from massive hot blue-white stars to much less massive red stars.
What is the brightest star on the Hr diagram?
i don't know about the hr diagram but the brightest star known is r136a1
Why is the hr diagram important to scientist?
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.
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.
Where is the Sun in the H-R diagram?
Our Sun is a G2V star and will thus appear in the centre of the HR diagram.
What information is needed to plot a star on the H-R diagram?
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
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.
What type of star has a high temperature and low luminosity in the HR diagram?
White dwarfs.
Most of the stars on the HR Diagram are classified as which type of star?
stars there called stars
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.
Are most of the stars on the HR diagram are classified as which type of star?
