What are the four categories of the h-r diagram?
The four categorys are main sequence, white dwarfs, red gaint, and super giants.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.

The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
What does main sequence mean?
The Hertzsprung-Russell diagram is a scatter graph of stars in which a star's luminosity (brightness) is plotted against its colour (temperature). Stars are not distributed all over this chart. A majority of stars lie on or near the diagonal which goes from top left (hot and bright) to bottom left (cooler and less bright). These are the main sequence stars.There are also white dwarfs which are below the main sequence whereas stars which are giants and super giants lie in the region above the main sequence.
Why giants are not in the main sequence on the H-R diagram?
Because there not that hot
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
How much farther away are the red giants compared to the main-sequence of stars?
Red giants are a later stadium of main sequence stars, there is no relation between distance and position in the Hertzsprung Russell diagram.
Why are giants not on the main sequence?
Because, giants can only occur once they leave the main sequence.
What are the four categories of the h-r diagram?
The four categorys are main sequence, white dwarfs, red gaint, and super giants.
What element is the main fuel for red giants main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
What red giants element is the main fuel for main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
What is a diagonal band of stars on the H-R diagram?
Main sequence stars.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
What kind of stars are in a band down the the middle of a Hertsprung-Russell diagram?
That's more or less the description of the so-called "main sequence". Those are the stars that get their energy by fusing hydrogen into helium.
