=== Sample parameters === The table below shows typical values for stars along the main sequence. The values of [[luminosity]] (''L''), [[radius]] (''R''), and [[mass]] (''M'') are relative to the Sunβa dwarf star with a spectral classification of G2 V. The actual values for a star may vary by as much as 20β30% from the values listed below.<ref name=siess00/>{{Why|date=December 2023}} <!-- Please include a solid reference if you add additional values to this table. --> {| class="wikitable" |+ Table of main-sequence stellar parameters<ref name=zombeck/> |- !
