Add to ORKG30-32About 400 years ago, Italian scientist Galileo observed spots on the sun and found that Sun rotates around its own axis. In a cycle of 11 years, the sunspot number goes from a minimum to a maximum
Annual sunspot numbers since 1700 and the known maxima and minima since 1610 show a similarity of pa...
