# On a Hertzsprung-Russell diagram, where would we find stars that have the largest radii?

Mar 30, 2018

#### Answer:

The radius of the stars is represented as diagonal on a HR diagram in logarithmic scale. Stars with largest radii are on the top diagonal of the HR diagram.

#### Explanation:

Remember the equation:
${m}_{1} - {m}_{2} = - 2.5 \cdot {\log}_{10} \left({j}_{1} / {j}_{2}\right)$
