Sun ‘less active’ than similar stars


The Sun is less magnetically active and shows less variability in its brightness than similar stars in the galaxy, scientists say.

To come to this conclusion, published in the journal Science, they analysed 369 candidate stars selected because they resemble the Sun in decisive properties.

“These stars appear nearly identical to the Sun except for their higher variability. Therefore, we speculate that the Sun could potentially also go through epochs of such high variability,” they write.
