red dwarf is the most nearest star.
The H-R diagram constructed from the data on the brightest stars differs from the diagram constructed from data on the nearest stars because the brightest stars are typically more massive and have higher luminosities, while the nearest stars may include a mix of different masses and luminosities. This leads to a different distribution of stars in the diagram, with the brightest stars clustering in different regions compared to the nearest stars.
No, they are mostly red dwarf stars.
20 IS itself an integer and so is the nearest. Answer: 20
