Question

which statement correctly explains how the hertzsprung - russell diagram helps to compare stars? (1 point)
the hertzsprung - russell diagram plots stars according to their luminosity and temperature, which is also associated with spectral class.
stars with the highest temperatures appear towards the right side of the hertzsprung - russell diagram.
the hertzsprung - russell diagram plots stars according to their size and shape.
the suns high temperature places it to the far left of the hertzsprung - russell diagram.

Explanation:

The Hertzsprung - Russell (H - R) diagram is a plot of stars based on luminosity and temperature (which is related to spectral class). Hotter stars are on the left side of the H - R diagram, not the right. It does not plot based on size and shape. The Sun is a G - type star and is not in the far - left (hot) region.

Answer:

The Hertzsprung - Russell diagram plots stars according to their luminosity and temperature, which is also associated with spectral class.
