According to the hertzsprung Russell diagram what color is are sun?
On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.
How bright is a star?
That depends and which star you are talking about, for instant, our sun is three hundred dimer then Sirius. Our sun releases 1.4x10 to the power 31 joules every hour, whilst Sirius releases 4.2x10 to the power of 33 every hour.
What location on the graph best represents a star with average brightness and temperature?
Stars' brightness and temperature are typically represented on a Hertzsprung-Russell (H-R) diagram. An average star like the Sun would be located on the "Main Sequence" portion of the graph, where brightness increases as temperature increases.
Why is the sun called a main sequence star?
The main sequence is a line on a Hertzsprung-Russell diagram, on which every star is placed on a graph of absolute magnitude against surface temperature. Each star produces a dot on the diagram, and all the main sequence stars fall roughly on a straight line. On the main sequence the hot bright stars are on the top left and the cooler dimmer red stars are on the lower right. The Sun is just above halfway up.
How do we know that the Sun is made mostly of hydrogen and helium?
If the star plots on the main sequence of the Hertzsprung-Russell (HR) diagram its main energy source is hydrogen fusion. As it converts to helium fusion the core collapses a bit and the temperature of the core goes up. This causes the star's outer layers to expand and the star's surface appears cooler (more red). At this point it will no longer plot on the main sequence of the HR diagram.
How would you classify the based on each of these characteristics?
The sun is considered a main sequence star on the Hertzsprung-Russell diagram.
Is the star pollux already on the diagram of hertzsprung Russell?
Pollux is an orange giant star located about 34 light years from earth. It would no doubt have been used to help form the Hertzsprung-Russell diagram, showing temperatures of stars vs. luminosity. Its temperature is around 4865 Kelvin and it has a luminosity of 32 times that of our own sun.
According to the hertzsprung Russell diagram what color is are sun?
On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.
According to the Hertzsprung Russell Diagram what is the luminosity of the Sun?
The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.
Stars that are larger than the sun are called?
Have a crack at the Hertzsprung - Russell diagram of stars. This will give you an idea of where Sol is in the Stellar hierarchy.

Your sun is classified as what kind of star?
star
What category of star is considered the largest star?
VY Canis Majoris [See Link] has the largest diameter of any known star, 1800 to 2100 times that of the Sun. This gives it a similar diameter to the orbit of Saturn. It is classed as a red super-giant , high luminosity M star as per the stellar classification [See Link] putting it at the upper right hand corner of the Hertzsprung--Russell diagram [See Link]
Why is the sun called a main sequence star?
The main sequence is a line on a Hertzsprung-Russell diagram, on which every star is placed on a graph of absolute magnitude against surface temperature. Each star produces a dot on the diagram, and all the main sequence stars fall roughly on a straight line. On the main sequence the hot bright stars are on the top left and the cooler dimmer red stars are on the lower right. The Sun is just above halfway up.
What kind of star is the sun considered to be called?
The Sun is a yellow dwarf star.
What kind of planet is the sun?
The sun is a star, not a planet.
