The Sun is our closest star and it has been studied in great details for centuries. Fundamental questions however, still remain unanswered. These are questions like: how large flares is the Sun capable of producing? What was the nature of the Sun during the Maunder Minimum in the 17th century and how did it effect the Earth? I will present two secondary approaches in which we can seek answers to these questions: the study of other Sun-like stars and reconstruction of past solar activity through measurements of 14C in tree rings and 10Be in ice cores.
