Events Polar Star

The brightness of the polar star is because the star evolves.

The brightness of the Polar star is undergoing changes lately. Every four days it makes a pulse, but currently the pulses are barely noticeable, and in the last two thousand years they shine 150% more.

These changes are due to the evolution of the star. The proportions of hydrogen and helium are changing, causing a change of brightness.
