Why don't we see many common stars in The Hertzsprung -Russell H-R diagrams?

Most of the stars - the red dwarves - are very faint. Even the star that is closest to us (next to the Sun), Proxima Centauri, is too faint to see with the naked eye, even though the distance is only a little over 4 light-years.

Who were Enjar Hertzsprung and Henry Russell?
Enjar Hertzsprung lived in 1873-1967 and Henry Russell lived in 1877-1957. They were scientists who worked separtely. They found the same answer about the temperature and color of stars. The diagram that they made is called the Hertzsprung-Russell diargram. It shows the connection between surface temperature and color.The discoverers of the famous Hertzsprung-Russel diagram (HR diagram), which turned out to be an important tool for the analysis of stars.
The region of the Hertzsprung-Russell diagram with the most stars is the what?
The main sequence - the region across the middle of the diagram.
How does the hertzsprung Russell diagram classify stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
What is the name of the person that discovered the relationship between a star's temperature and its brightness?
The two people who discovered the relationship between a star's temperature and its brightness were Ejnar Hertzsrung and H.N. Russell. The two men were working from research that had been done by Ludwig Boltzmann and Joseph Stefan.
What is a red gigant?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
When was the hertzsprung-Russell diagram invented?
The diagram was created by Ejnar Hertzsprung and Henry Norris Russell aound 1910.
The hertzsprung-russell diagram graphs stars' brightness and?
The Hertzsprung-Russell diagram graphs stars' brightness and corresponding temperatures in addition to their classifications. The stars' colors are due to their temperatures.
